Accounting Changes and Error Corrections [Abstract] | |
Accounting Changes and Error Corrections [Text Block] | Recent Accounting Changes and Accounting Pronouncements Recent Accounting Pronouncements Adopted Revenue Recognition In April 2014, the Financial Accounting Standards Board (FASB) issued the authoritative guidance, as amended, that outlines a new revenue recognition standard that replaces virtually all existing U.S. GAAP guidance on contracts with customers and the related other assets and deferred costs. The authoritative guidance provides a five-step process for recognizing revenue that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled, in exchange for those goods or services. The new guidance also requires expanded qualitative and quantitative disclosures relating to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance is required to be applied retrospectively to each prior reporting period presented (Full Retrospective), or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. The Company adopted the new guidance on April 1, 2018, using the Full Retrospective method and restated the comparative prior periods. The Company implemented internal controls and certain system functionality to enable the preparation of financial information on adoption. As a result of the adoption of the authoritative guidance, the Company changed its accounting policy for revenue recognition and the details of the significant changes and quantitative impact of the changes are disclosed below: Revenue from sales to the Company's distributors is recognized upon shipment of the product to the distributors (sell-in) and is reduced by estimated allowances for distributor price adjustments and rights of return. Previously, revenue was recognized upon reported resale of the product by the distributors to their customers (sell-through) as reduced by actual allowances for distributor price adjustments. Revenue from software license agreements, software license renewals, and other contracts are recognized at point of sales, whereas previously these were deferred and recognized over the contractual term before the implementation of the authoritative guidance. Revenue recognition related to the Company's other revenue streams, such as direct customers, remains unchanged. The adoption of this authoritative guidance has an impact on the Company’s condensed consolidated statements of income and balance sheets, but has no impact on net cash provided by or used in operating, financing, or investing activities on the condensed consolidated statements of cash flows. The impact on the Company's previously reported condensed consolidated statement of income resulting from the adoption of the authoritative guidance is as follows: Three Months Ended September 30, 2017 Six Months Ended September 30, 2017 (In thousands, except per share amounts) As Reported Adjustment As Adjusted As Reported Adjustment As Adjusted Net revenues $ 619,503 $ 7,916 $ 627,419 $ 1,234,949 $ (4,720 ) $ 1,230,229 Cost of revenues 184,786 899 185,685 376,881 (372 ) 376,509 Gross margin 434,717 7,017 441,734 858,068 (4,348 ) 853,720 Operating expenses: Research and development 157,985 — 157,985 311,036 — 311,036 Selling, general and administrative 91,053 — 91,053 180,228 — 180,228 Amortization of acquisition-related intangibles 510 — 510 1,215 — 1,215 Total operating expenses 249,548 — 249,548 492,479 — 492,479 Operating income 185,169 7,017 192,186 365,589 (4,348 ) 361,241 Interest and other income, net 1,831 — 1,831 3,669 — 3,669 Income before income taxes 187,000 7,017 194,017 369,258 (4,348 ) 364,910 Provision for income taxes 19,468 798 20,266 34,481 (566 ) 33,915 Net income $ 167,532 $ 6,219 $ 173,751 $ 334,777 $ (3,782 ) $ 330,995 Net income per common share: Basic $ 0.68 $ (0.02 ) $ 0.70 $ 1.35 $ (0.02 ) $ 1.33 Diluted $ 0.65 $ (0.02 ) $ 0.67 $ 1.28 $ (0.02 ) $ 1.26 Shares used in per share calculations: Basic 248,094 248,094 247,960 247,960 Diluted 258,217 258,217 261,739 261,739 The impact on the Company's previously reported condensed consolidated balance sheet line items affected by the adoption of the authoritative guidance is as follows: March 31, 2018 (In thousands) As Reported Adjustment As Adjusted Accounts receivable $ 372,144 $ 10,102 $ 382,246 Other assets 342,644 (5,242 ) 337,402 Deferred income on shipments to distributors 25,166 (25,166 ) — Other accrued liabilities 59,772 (92 ) 59,680 Retained earnings 1,483,538 30,118 1,513,656 Financial Instruments In January 2016, the FASB issued final authoritative guidance regarding how companies measure equity investments that do not result in consolidation and are not accounted for under the equity method and how they present changes in the fair value of financial liabilities measured under the fair value option that are attributable to their own credit. The authoritative guidance also changes certain disclosure requirements and other aspects of current U.S. GAAP on this matter. The authoritative guidance does not change the guidance for classifying and measuring investments in debt securities and loans. The authoritative guidance is effective for public business entities for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The Company adopted this authoritative guidance on April 1, 2018 and recorded the balance of the unrealized losses of $11.0 million as of the end of fiscal 2018 from its investment in debt mutual funds and equity securities to retained earnings, less the related deferred taxes of $2.6 million . Subsequent changes in fair value from such investments are recorded in the condensed consolidated statements of income. Income Taxes In October 2016, the FASB issued authoritative guidance on income taxes which eliminates the deferred tax effects of intra-entity asset transfers other than inventory. As a result, a reporting entity would recognize the tax expense from the sale of an asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. The authoritative guidance is effective for public business entities in fiscal years beginning after December 15, 2017 and requires the adoption be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings. The Company adopted this authoritative guidance on April 1, 2018. Accordingly, $13.8 million of prepaid taxes associated with prior period intra-entity asset transfers was reclassified to retained earnings. Recent Accounting Pronouncements Not Yet Adopted Leases In February 2016, the FASB issued authoritative guidance on leases. The new authoritative guidance requires the recognition of assets and liabilities arising from lease transactions on the balance sheet and will also require significant additional disclosures about the amount, timing and uncertainty of cash flows from leases. Accordingly, a lessee will recognize a lease asset for its right to use the underlying asset and a lease liability for the corresponding lease obligation. The new authoritative guidance is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, which for Xilinx would be the first quarter of fiscal 2020. Early adoption is permitted. The new authoritative guidance must be adopted using a modified retrospective transition with application of the new authoritative guidance for leases that existed at or are entered after the beginning of the earliest comparative period presented. To help with the transition to the new guidance, certain practical expedients are provided. The Company is currently evaluating the impact of this new authoritative guidance on its condensed consolidated financial statements. On July 30, 2018, The FASB provided entities with an additional (and optional) transition method to adopt the new lease requirements by allowing entities to initially apply the requirements by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which the entity adopts the new lease requirements would continue to be in accordance with current GAAP. An entity electing this additional (and optional) transition method must provide the required disclosures for all periods that continue to be in accordance with current GAAP. The amendments do not change the existing disclosure requirements in current GAAP. The amendments have the same effective date as the new leases standard, which for Xilinx would be the first quarter of fiscal 2020. The Company is currently evaluating the impact of this new authoritative guidance on its condensed consolidated financial statements. Cloud Computing Arrangements On August 29, 2018, the FASB issued new guidance requiring a customer in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized implementation costs related to a hosting arrangement that is a service contract will be amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. Entities will need to maintain appropriate records to capture the portion of their costs that qualify for capitalization. For public entities, the guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, which for Xilinx would be the first quarter of fiscal 2021. Early adoption is permitted, including adoption in any interim period. Entities have the option to apply the guidance prospectively to all implementation costs incurred after the date of adoption or retrospectively. The Company is currently evaluating the impact of this new authoritative guidance on its condensed consolidated financial statements. |

Significant Customers and Concentrations of Credit Risk [Abstract] | |
Concentration Risk Disclosure [Text Block] | Significant Customers and Concentrations of Credit Risk Avnet, Inc. (Avnet), one of the Company’s distributors, distributes the Company’s products worldwide. As of September 29, 2018 and March 31, 2018 , Avnet accounted for 50% and 61% of the Company’s total net accounts receivable, respectively. The Company expects its accounts receivable to fluctuate as the Company partners with its distributors to manage their inventory requirements. For the second quarter and first six months of fiscal 2019, resale of product through Avnet accounted for 46% and 48% of the Company's worldwide net revenues, respectively. For the second quarter and first six months of fiscal 2018, resale of product through Avnet accounted for 46% and 43% of the Company’s worldwide net revenues, respectively. Xilinx is subject to concentrations of credit risk primarily in its trade accounts receivable and investments in debt securities to the extent of the amounts recorded on the condensed consolidated balance sheet. The Company attempts to mitigate the concentration of credit risk in its trade receivables through its credit evaluation process, collection terms, distributor sales to diverse end customers and through geographical dispersion of sales. Xilinx generally does not require collateral for receivables from its end customers or distributors. No end customer accounted for more than 10% of the Company’s worldwide net revenues for the second quarter and first six months of fiscal 2019 and 2018 . The Company mitigates concentrations of credit risk in its investments in debt securities by currently investing approximately 91% of its portfolio in AA (or its equivalent) or higher grade securities as rated by Standard & Poor’s or Moody’s Investors Service. The Company’s methods to arrive at investment decisions are not solely based on the rating agencies’ credit ratings. Xilinx also performs additional credit due diligence and conducts regular portfolio credit reviews, including a review of counterparty credit risk related to the Company’s forward currency exchange and interest rate swap contracts. Additionally, Xilinx limits its investments in the debt securities of a single issuer based upon the issuer’s credit rating and attempts to further mitigate credit risk by diversifying risk across geographies and type of issuer. As of September 29, 2018 , approximately 23% of the portfolio consisted of mortgage-backed securities. All of the mortgage-backed securities in the investment portfolio were issued by U.S. government-sponsored enterprises and agencies and are rated AA+ by Standard & Poor’s and Aaa by Moody’s Investors Service. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements The authoritative guidance for fair value measurements established by the FASB defines fair value as the exchange price that would be received from selling an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which Xilinx would transact. The Company also considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions and risk of nonperformance. The Company determines the fair value for marketable debt securities using industry standard pricing services, data providers and other third-party sources and by internally performing valuation testing and analysis. The Company primarily uses a consensus price or weighted-average price for its fair value assessment. The Company determines the consensus price using market prices from a variety of industry standard pricing services, data providers, security master files from large financial institutions and other third-party sources and uses those multiple prices as inputs into a distribution-curve-based algorithm to determine the daily market value. The pricing services use multiple inputs to determine market prices, including reportable trades, benchmark yield curves, credit spreads and broker/dealer quotes as well as other industry and economic events. For certain securities with short maturities, such as discount commercial paper and certificates of deposit, the security is accreted from purchase price to face value at maturity. If a subsequent transaction on the same security is observed in the marketplace, the price on the subsequent transaction is used as the current daily market price and the security will be accreted to face value based on the revised price. The Company validates the consensus prices by taking random samples from each asset type and corroborating those prices using reported trade activity, benchmark yield curves, binding broker/dealer quotes or other relevant price information. There have not been any changes to the Company’s fair value methodology during the second quarter and first six months of fiscal 2019 and the Company did not adjust or override any fair value measurements as of September 29, 2018 . Fair Value Hierarchy The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. The guidance for fair value measurements requires that assets and liabilities carried at fair value be classified and disclosed in one of the following categories: Level 1 — Quoted (unadjusted) prices in active markets for identical assets or liabilities. The Company’s Level 1 assets consist of U.S. government securities, money market funds and marketable equity securities. Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. The Company’s Level 2 assets consist of financial institution securities, non-financial institution securities, U.S. agency securities, foreign government and agency securities, mortgage-backed securities, debt mutual funds, asset-backed securities and commercial mortgage-backed securities. The Company’s Level 2 assets and liabilities also include foreign currency forward contracts and interest rate swap contracts. Level 3 — Unobservable inputs to the valuation methodology that are supported by little or no market activity and that are significant to the measurement of the fair value of the assets or liabilities. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques, as well as significant management judgment or estimation. The Company has no Level 3 assets and liabilities measured at fair value on a recurring basis. Assets and Liabilities Measured at Fair Value on a Recurring Basis In instances where the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring basis as of September 29, 2018 and March 31, 2018 : September 29, 2018 (In thousands) Quoted Significant Significant Total Fair Assets Cash equivalents: Money market funds $ 376,673 $ — $ — $ 376,673 Financial institution securities — 403,980 — 403,980 Non-financial institution securities — 476,957 — 476,957 U.S. government and agency securities 114,891 162,887 — 277,778 Foreign government and agency securities — 370,791 — 370,791 Short-term investments: Financial institution securities — 225,000 — 225,000 Non-financial institution securities — 96,379 — 96,379 U.S. government and agency securities 2,663 12,844 — 15,507 Mortgage-backed securities — 749,426 — 749,426 Asset-backed securities — 85,421 — 85,421 Commercial mortgage-backed securities — 134,189 — 134,189 Long-term investments: Debt mutual funds — 84,926 — 84,926 Marketable equity securities 6,701 — — 6,701 Total assets measured at fair value $ 500,928 $ 2,802,800 $ — $ 3,303,728 Liabilities Derivative financial instruments, net $ — $ 47,791 $ — $ 47,791 Total liabilities measured at fair value $ — $ 47,791 $ — $ 47,791 Net assets measured at fair value $ 500,928 $ 2,755,009 $ — $ 3,255,937 March 31, 2018 (In thousands) Quoted Significant Significant Total Fair Assets Cash equivalents: Money market funds $ 1,291,891 $ — $ — $ 1,291,891 Financial institution securities — 359,901 — 359,901 Non-financial institution securities — 242,904 — 242,904 U.S. government and agency securities 996 34,999 — 35,995 Foreign government and agency securities — 179,957 — 179,957 Short-term investments: Financial institution securities — 75,000 — 75,000 Non-financial institution securities — 81,939 — 81,939 U.S. government and agency securities 3,639 19,008 — 22,647 Mortgage-backed securities — 844,397 — 844,397 Asset-backed securities — 91,389 — 91,389 Commercial mortgage-backed securities — 152,870 — 152,870 Long-term investments: Debt mutual funds — 89,670 — 89,670 Marketable equity securities 8,226 — 8,226 Total assets measured at fair value $ 1,304,752 $ 2,172,034 $ — $ 3,476,786 Liabilities Derivative financial instruments, net $ — $ 26,091 $ — $ 26,091 Total liabilities measured at fair value $ — $ 26,091 $ — $ 26,091 Net assets measured at fair value $ 1,304,752 $ 2,145,943 $ — $ 3,450,695 For certain of the Company’s financial instruments, including cash held in banks, accounts receivable and accounts payable, the carrying amounts approximate fair value due to their short maturities, and are therefore excluded from the fair value tables above. Financial Instruments Not Recorded at Fair Value on a Recurring Basis The Company's $500.0 million principal amount of 2.125% notes due March 15, 2019 (2019 Notes) and $500.0 million principal amount of 3.000% notes due March 15, 2021 (2021 Notes) are measured at fair value on a quarterly basis for disclosure purposes. The fair values of the 2019 Notes and 2021 Notes as of September 29, 2018 were approximately $498.7 million and $495.2 million , respectively, based on the last trading price for the period (classified as Level 2 in fair value hierarchy due to relatively low trading volume). Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis As of September 29, 2018 , the Company had non-marketable equity securities in private companies of $53.8 million , which were classified as Level 3 assets. The Company’s investments in non-marketable securities of private companies, together with its non-financial assets such as property, plant and equipment, goodwill and acquisition-related intangibles, are recorded at fair value only if the Company recognizes an impairment. The Company’s investments in non-marketable securities of private companies are also recorded at fair value if the Company recognizes an observable price adjustments. Such impairment losses or observable price adjustments were not material during all periods presented. |

The following tables show the fair values and gross unrealized losses of the Company’s investments, aggregated by investment category, for individual securities that have been in a continuous unrealized loss position for the length of time specified, as of September 29, 2018 and March 31, 2018 : September 29, 2018 Less Than 12 Months 12 Months or Greater Total (In thousands) Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Non-financial institution securities $ 44,067 $ (748 ) $ 19,640 $ (546 ) $ 63,707 $ (1,294 ) U.S. government and agency securities — — 15,507 (337 ) 15,507 (337 ) Mortgage-backed securities 222,604 (5,996 ) 497,433 (20,860 ) 720,037 (26,856 ) Asset-backed securities 18,472 (278 ) 65,425 (974 ) 83,897 (1,252 ) Debt mutual funds — — 84,926 (16,424 ) 84,926 (16,424 ) Commercial mortgage- backed securities 44,231 (950 ) 88,823 (2,629 ) 133,054 (3,579 ) Marketable equity securities 6,701 (799 ) — — 6,701 (799 ) $ 336,075 $ (8,771 ) $ 771,754 $ (41,770 ) $ 1,107,829 $ (50,541 ) March 31, 2018 Less Than 12 Months 12 Months or Greater Total (In thousands) Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Non-financial institution securities $ 69,780 $ (1,146 ) $ 8,344 $ (230 ) $ 78,124 $ (1,376 ) U.S. government and agency securities 13,471 (176 ) 9,176 (96 ) 22,647 (272 ) Mortgage-backed securities 510,988 (11,048 ) 299,663 (11,263 ) 810,651 (22,311 ) Asset-backed securities 57,128 (876 ) 32,696 (502 ) 89,824 (1,378 ) Debt mutual funds — — 89,670 (11,680 ) 89,670 (11,680 ) Commercial mortgage- backed securities 95,435 (1,760 ) 56,051 (1,667 ) 151,486 (3,427 ) $ 746,802 $ (15,006 ) $ 495,600 $ (25,438 ) $ 1,242,402 $ (40,444 ) As of September 29, 2018 , the gross unrealized losses that had been outstanding for less than twelve months were primarily related to mortgage-backed securities due to the general rising of the interest-rate environment, although the percentage of such losses to the total estimated fair value of the mortgage-backed securities was relatively insignificant. The gross unrealized losses that had been outstanding for more than twelve months were primarily related to debt mutual funds and mortgage-backed securities, which were primarily due to the general rising of the interest-rate environment and foreign currency movement. Starting April 1, 2018 , the Company records the change in the fair value of its investment in debt mutual funds and marketable equity securities as part of its interest and other income, net. This change in fair value was a net decrease of $73 thousand and $6.3 million for the three and six months ended September 29, 2018 , respectively, and resulted in an expense within interest and other income, net for the period. The Company reviewed the investment portfolio and determined that the gross unrealized losses on these investments as of September 29, 2018 and March 31, 2018 were temporary in nature as evidenced by the fluctuations in the gross unrealized losses within the investment categories. These investments are highly rated by the credit rating agencies, there have been no defaults on any of these securities and the company has received interest payments as they become due. Therefore, the Company believes that it will be able to collect both principal and interest amount due to the Company. Additionally, in the past several years a portion of the Company's investment in the mortgage-backed securities was redeemed or prepaid by the debtors at par. Furthermore, the aggregate of individual unrealized losses that had been outstanding for twelve months or more was not significant as of September 29, 2018 and March 31, 2018 . The Company neither intends to sell these investments nor concludes that it is more-likely-than-not that it will have to sell them until recovery of their carrying values. The amortized cost and estimated fair value of marketable debt securities (financial institution securities, non-financial institution securities, U.S. and foreign government and agency securities, asset-backed securities, mortgage-backed securities and commercial mortgage-backed securities), by contractual maturity, are shown in the table below. Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations without call or prepayment penalties.

Additionally, the above table does not include investments in money market, debt mutual funds and marketable equity securities because these investments do not have specific contractual maturities.

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Financial Instruments | Derivative Financial Instruments The Company’s primary objective for holding derivative financial instruments is to manage foreign currency exchange rate risk and interest rate risk. As a result of the use of derivative financial instruments, the Company is exposed to the risk that counterparties to derivative contracts may fail to meet their contractual obligations. The Company manages counterparty credit risk in derivative contracts by reviewing counterparty creditworthiness on a regular basis, establishing collateral requirement and limiting exposure to any single counterparty. The right of set-off that exists with certain transactions enables the Company to net amounts due to and from the counterparty, reducing the maximum loss from credit risk in the event of counterparty default. The Company entered into interest rate swap contracts with certain independent financial institutions to manage interest rate risks related to fixed interest rate expenses from its 2024 Notes and floating interest rate income from its investments in marketable debt securities. See “Note 10. Debt and Credit Facility” for more discussion related to interest rate swap contracts. The interest rate swap contracts were designated and qualified as fair value hedges of the 2024 Notes and were separately accounted for as a derivative. The interest rate swap contracts and the 2024 Notes were initially measured at fair value. Any subsequent changes in fair values of the interest rate swap contracts and the 2024 Notes will be recorded in the Company’s consolidated balance sheets. During the six months ended September 29, 2018 , the net change in fair values of the interest rate swap contracts and the underlying 2024 Notes was $13.3 million , which was recorded as a derivative liability for the interest rate swap contacts and as a reduction from the carrying amount of the 2024 Notes. There was no ineffectiveness during all periods presented. |

Stock-Based Compensation Plans | Stock-Based Compensation Plans The Company’s equity incentive plans are broad-based, long-term retention programs that cover employees, consultants and non-employee directors of the Company. These plans are intended to attract and retain talented employees, consultants and non-employee directors and to provide such persons with a proprietary interest in the Company. Stock-Based Compensation The following table summarizes stock-based compensation expense related to stock awards granted under the Company’s equity incentive plans and rights to acquire stock granted under the Company’s Employee Stock Purchase Plan (ESPP): Three Months Ended Six Months Ended (In thousands) September 29, 2018 September 30, 2017 September 29, 2018 September 30, 2017 Stock-based compensation included in: Cost of revenues $ 2,249 $ 2,147 $ 4,284 $ 4,297 Research and development 20,047 20,096 40,977 37,562 Selling, general and administrative 12,649 14,129 25,292 26,549 $ 34,945 $ 36,372 $ 70,553 $ 68,408 Employee Stock Option Plans The types of awards allowed under the 2007 Equity Incentive Plan (2007 Equity Plan) include incentive stock options, non-qualified stock options, restricted stock units (RSUs), restricted stock and stock appreciation rights. To date, the Company has issued a mix of non-qualified stock options and RSUs under the 2007 Equity Plan; however, there was no issuance of stock options during the first six months of fiscal 2019 and the entire fiscal 2018 . The Company's stock-based compensation expenses related to options during the first six months of fiscal 2019 and the number of options outstanding as of September 29, 2018 were not material. On August 1, 2018, the stockholders approved an amendment to increase the authorized number of shares reserved for issuance under the 2007 Equity Plan by 3.0 million shares. As of September 29, 2018 , 11.6 million shares remained available for grant under the 2007 Equity Plan. RSU Awards A summary of the Company’s RSU activity and related information is as follows: RSUs Outstanding (Shares in thousands) Number of Shares Weighted-Average Grant-Date Fair Value Per Share April 1, 2017 6,988 $ 42.93 Granted 3,718 $ 60.18 Vested (3,016 ) $ 43.30 Cancelled (701 ) $ 48.16 March 31, 2018 6,989 $ 51.39 Granted 2,964 $ 63.00 Vested (2,293 ) $ 48.60 Cancelled (251 ) $ 52.20 September 29, 2018 7,409 The estimated fair values of RSUs were calculated based on the market price of Xilinx common stock on the date of grant, reduced by the present value of dividends expected to be paid on Xilinx common stock prior to vesting. The per share weighted-average fair value of RSUs granted during the second quarter of fiscal 2019 was $62.79 ( $59.99 for the second quarter of fiscal 2018 ), and for the first six months of fiscal 2019 was $63.00 ( $59.89 for the first six months of fiscal 2018 ), which were calculated based on estimates at the date of grant using the following weighted-average assumptions: Three Months Ended Six Months Ended September 29, 2018 September 30, 2017 September 29, 2018 September 30, 2017 Risk-free interest rate 2.7 % 1.7 % 2.7 % 1.7 % Dividend yield 2.2 % 2.2 % 2.2 % 2.2 % For the majority of RSUs granted, the number of shares of common stock issued on the date the RSU awards vest is net of the minimum statutory withholding requirements that the Company pays in cash to the appropriate taxing authorities on behalf of the Company's employees. During the first six months of fiscal 2019 and 2018 , the Company withheld $39.5 million and $42.1 million worth of RSU awards, respectively, to satisfy the employees’ tax obligations. During the second quarter and the first six months of fiscal 2019 , the Company realized excess tax benefits of $7.8 million and $8.7 million , respectively, primarily from RSU vesting. During the second quarter and the first six months of fiscal 2018 , the Company realized excess tax benefits of $6.3 million and $17.9 million , respectively. These tax benefits were recorded in the condensed consolidated statements of income as a component of the provision for income taxes. Employee Stock Purchase Plan Under the ESPP, shares are only issued during the second and fourth quarters of each fiscal year. Employees purchased 359 thousand shares for $18.0 million during the second quarter of fiscal 2019 and 355 thousand shares for $16.9 million during the second quarter of fiscal 2018 . The per-share weighted-average fair value of stock purchase rights granted under the ESPP during the second quarter of fiscal 2019 and 2018 was $19.06 and $16.46 , respectively. The fair values of stock purchase plan rights granted in the second quarter of fiscal years 2019 and 2018 were estimated using the Black-Scholes option pricing model at the date of grant using the following assumptions: 2019 2018 Expected life of options (years) 1.25 1.25 Expected stock price volatility 0.29 0.28 Risk-free interest rate 2.5 % 1.3 % Dividend yield 2.0 % 2.2 % The next scheduled purchase under the ESPP is in the fourth quarter of fiscal 2019 . On August 1, 2018, the stockholders approved an amendment to increase the authorized number of shares reserved for issuance under the ESPP by 3.0 million shares. As of September 29, 2018 , 12.0 million shares were available for future issuance under the ESPP. |

Earnings Per Share [Abstract] | |
Net Income Per Common Share | Net Income Per Common Share The computation of basic net income per common share for all periods presented is derived from information on the condensed consolidated statements of income, and there are no reconciling items in the numerator used to compute the diluted net income per common share. The following table summarizes the computation of basic and diluted net income per common share: Three Months Ended Six Months Ended (In thousands, except per share amounts) September 29, 2018 September 30, 2017 September 29, 2018 September 30, 2017 Net income available to common stockholders $ 215,712 $ 173,751 $ 405,750 $ 330,995 Weighted average common shares outstanding-basic 252,988 248,094 252,541 247,960 Dilutive effect of employee equity incentive plans 2,534 2,532 2,516 2,949 Dilutive effect of 2017 Convertible Notes — — — 2,986 Dilutive effect of warrants — 7,591 — 7,844 Weighted average common shares outstanding-diluted 255,522 258,217 255,057 261,739 Basic net income per common share $ 0.85 $ 0.70 $ 1.61 $ 1.33 Diluted net income per common share $ 0.84 $ 0.67 $ 1.59 $ 1.26 The total shares used in the denominator of the diluted net income per common share calculation include potentially dilutive common equivalent shares outstanding that are not included in basic net income per common share calculation. The diluted shares were calculated by applying the treasury stock method to the impact of the equity incentive plans, the incremental shares issuable assuming conversion of the Company's $600.0 million principal amount of 2.625% convertible notes issued in June 2010 (2017 Convertible Notes), before its maturity on June 15, 2017 , and exercise of warrants on a weighted-average outstanding basis, before the final settlements during the third quarter of fiscal 2018. The 2017 Convertible Notes matured during the first quarter of fiscal 2018, and the Company exercised its call options to neutralize the dilutive effect of the incremental shares from the 2017 Convertible Notes. Because the number of diluted shares in the above table for the six months ended September 30, 2017 was calculated based on a weighted-average outstanding basis, it included approximately 3.0 million shares of dilutive impact from the 2017 Convertible Notes through the maturity date. Such impact will no longer be applicable in future periods. Outstanding stock options and RSUs under the Company's stock award plans to purchase approximately 1.8 million and 3.0 million shares for the second quarter and first six months of fiscal 2019 , respectively, were excluded from the diluted net income per common share calculation by applying the treasury stock method, as their inclusion would have been antidilutive. These options and RSUs could be dilutive in the future if the Company’s average share price increases and is greater than the combined exercise prices and the unamortized fair values of these options and RSUs. |

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes The Company recorded a tax provision of $23.4 million and $46.3 million for the second quarter and the first six months of fiscal 2019 , respectively, representing effective tax rates of 9.8% and 10.2% , respectively. The Company recorded tax provisions of $20.3 million and $33.9 million for the second quarter and the first six months of fiscal 2018, respectively, representing effective tax rates of 10.4% and 9.3% , respectively. The prior year amounts have been restated to reflect the retrospective application of the current authoritative guidance for revenue recognition. Refer to "Note 2. Recent Accounting Changes and Accounting Pronouncements" for additional detail. On December 22, 2017, the Tax Cuts and Jobs Act (TCJA) was enacted into law. The TCJA provides numerous significant tax law changes including the reduction of the U.S. federal corporate income tax rate from 35% to 21%, the requirement for companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and the creation of new taxes on certain foreign-sourced earnings. Some provisions of the TCJA began to impact the Company in fiscal 2018, while other provisions impact the Company beginning in fiscal 2019. In accordance with Staff Accounting Bulletin (SAB) 118, the Company has recorded provisional amounts recognizing the effect of the tax law changes in prior periods, but may adjust those provisional amounts during a measurement period that is similar to the measurement period used when accounting for business combinations. As a result of updated technical guidance related to the TCJA, the Company revised its provisional estimate recorded in prior periods. The application of this guidance resulted in an increase to tax expense of $9.4 million in the second quarter of fiscal 2019. The amount recorded for the one-time transition tax remains provisional as the Company has not yet finalized its calculation of the total post-1986 earnings and profits (E&P) for its foreign subsidiaries. Additionally, the Company will continue to evaluate the impact of the tax law change as it relates to providing U.S. taxes on its investments in foreign subsidiaries. Since U.S. federal taxes have been recognized through the one-time transition tax on all accumulated and previously untaxed foreign earnings through December 31, 2017, the Company does not intend to permanently reinvest those earnings. The difference between the U.S. federal statutory tax rate of 21% and the Company's effective tax rate in the second quarter and the first six months of fiscal 2019 was primarily due to the favorable impact of income earned in lower tax rate jurisdictions, which was partially offset by the new tax on low-taxed income from foreign subsidiaries. The difference between the U.S. federal statutory tax rate of 35% and the Company’s effective tax rate in the second quarter and the first six months of fiscal 2018 was primarily due to income earned in lower tax rate jurisdictions, for which no U.S. income tax had been provided, as the Company had intended to permanently reinvest the earnings outside of the U.S. The Company’s total gross unrecognized tax benefits for the second quarter and the first six months of fiscal 2019, determined in accordance with FASB authoritative guidance for measuring uncertain tax positions, increased by an immaterial amount to $126.1 million . The total amount of unrecognized tax benefits that, if realized in a future period, would favorably affect the effective tax rate was $16.1 million as of September 29, 2018 . Another $85.5 million would increase additional paid-in capital. The $85.5 million relates to an additional deduction claimed on federal and state amended tax returns for fiscal 2014 for repurchase premium paid in that year in connection with the early redemption of the Company’s 3.125% Junior Convertible debenture due March 15, 2037. It is reasonably possible that changes to the Company's unrecognized tax benefits could be significant in the next twelve months due to tax audit settlements and lapses of statutes of limitation. As a result of uncertainties regarding tax audit settlements and their possible outcomes, an estimate of the range of increase or decrease that could occur in the next twelve months cannot be made. The Company’s policy is to include interest and penalties related to income tax liabilities within the provision for income taxes on the condensed consolidated statements of income. The balance of accrued interest and penalties recorded in the condensed consolidated balance sheets and the amounts of interest and penalties included in the Company's provision for income taxes were not material for all periods presented. The statutes of limitations have closed for U.S. federal income tax purposes for years through fiscal 2014, for U.S. state income tax purposes for years through fiscal 2010, and for Ireland income tax purposes for years through fiscal 2013. |

Product Warranties Disclosures [Abstract] | |
Product Warranty Disclosure [Text Block] | Product Warranty and Indemnification The Company generally sells products with a limited warranty for product quality. The Company provides an accrual for known product issues if a loss is probable and can be reasonably estimated. As of the end of the second quarter of fiscal 2019 and the end of fiscal 2018 , the accrual balances of the product warranty liability were immaterial. The Company offers, subject to certain terms and conditions, to indemnify customers and distributors for costs and damages awarded against these parties in the event the Company’s hardware products are found to infringe third-party intellectual property rights, including patents, copyrights or trademarks, and to compensate certain customers for limited specified costs they actually incur in the event the Company's hardware products experience epidemic failure. To a lesser extent, the Company may from time-to-time offer limited indemnification with respect to its software products. The terms and conditions of these indemnity obligations are limited by contract, which obligations are typically perpetual from the effective date of the agreement. The Company has historically received only a limited number of requests for indemnification under these provisions and has not made any significant payments pursuant to these provisions. The Company cannot estimate the maximum amount of potential future payments, if any, that the Company may be required to make as a result of these obligations due to the limited history of indemnification claims and the unique facts and circumstances that are likely to be involved in each particular claim and indemnification provision. However, there can be no assurances that the Company will not incur any financial liabilities in the future as a result of these obligations. |

Loss Contingency [Abstract] | |
Contingencies | Contingencies Patent Litigation On February 1, 2017, a patent infringement lawsuit was filed by Godo Kaisha IP Bridge 1 (IP Bridge) against the Company in the U.S. District Court for the Eastern District of Texas (Godo Kaisha IP Bridge 1 v. Xilinx, Inc., Case. No. 2:17-cv-00100). The lawsuit pertains to two patents and IP Bridge seeks unspecified damages, interest, attorneys’ fees, costs, and a permanent injunction or an on-going royalty. On September 14, 2017, the court granted the Company’s motion to transfer venue and the matter is now pending before the U.S. District Court for the Northern District of California. The Company is unable to estimate its range of possible loss, if any, in this matter at this time. On March 17, 2017, a patent infringement lawsuit was filed by Anza Technology, Inc. (Anza) against the Company in the U.S. District Court for the District of Colorado (Anza Technology, Inc. v. Xilinx, Inc., Case No. 1:17-cv-00687). The lawsuit pertains to three patents and Anza seeks unspecified damages, attorney fees, interest, costs, and expenses. On October 27, 2017, the court granted the Company’s motion to transfer venue to the U.S. District Court for the Northern District of California. The parties reached an agreement to settle the lawsuit and it was dismissed with prejudice on July 23, 2018. The amount of the settlement did not have a material impact on the Company's financial position or results of operations. The Company intends to continue to protect and defend its IP vigorously. Other Matters On June 11, 2015, John P. Neblett, as Chapter 7 Trustee of Valley Forge Composite Technologies, Inc., filed a complaint against Xilinx and others in the U.S. Bankruptcy Court for the Middle District of Pennsylvania (Bankruptcy No. 1:13-bk-05253-JJT). The complaint alleges causes of actions against Xilinx for negligence and civil conspiracy relating to alleged violations of U.S. export laws. It seeks at least $50.0 million in damages, together with punitive damages, from the defendants. On September 21, 2015, the action was withdrawn from the U.S. Bankruptcy Court for the Middle District of Pennsylvania and transferred to the U.S. District Court for the Eastern District of Kentucky. On November 2, 2015, Xilinx, along with other defendants, filed a motion to dismiss the complaint. On November 3, 2015, Xilinx filed a motion for sanctions pursuant to Federal Rule of Civil Procedure 11. On June 27, 2016, the Court denied both motions. On September 11, 2017, Xilinx, along with other defendants, filed motions for summary judgment seeking to dispose of all claims against them. On July 3, 2018, the Court granted both of Xilinx’s Motions for Summary Judgment, disposing of all claims asserted against Xilinx. On August 1, 2018, the Trustee filed a Notice of Appeal. On August 9, 2018, the Court of Appeals for the Sixth Circuit issued an Order to Show Cause requesting that the appellant address a possible jurisdictional defect. On August 29, 2018, the appellant responded to the Order to Show Cause. On September 10, 2018, the appellees, including Xilinx, filed a joint reply. The Court of Appeals has not issued a further order. From time to time, the Company is involved in various disputes and litigation matters that arise in the ordinary course of its business. These include disputes and lawsuits related to intellectual property, mergers and acquisitions, licensing, contract law, tax, regulatory, distribution arrangements, employee relations and other matters. Periodically, the Company reviews the status of each matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and a range of possible losses can be estimated, the Company accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based only on the best information available at the time. As additional information becomes available, the Company continues to reassess the potential liability related to pending claims and litigation and may revise estimates. |
