BEAVERTON, Ore.--(BUSINESS WIRE)--March 3, 2000

Summit Design, Inc. today announced that Rich Davenport, its President and COO,
resigned his positions with the company at the end of February.

William V. Botts, Summit Design's Chairman of the Board and Chief Executive

the planned merger with Viewlogic Systems Inc. Davenport has been retained as a
consultant to Summit undertaking special projects and support to integration of
the merged companies once the merger has been concluded.

Davenport has been active with Summit Design and SimTech, a company he founded
that was acquired by Summit in 1997, for over nine years. He planned to scaled
back his activities as the merger was completed. Today's change was in
contemplation of the proposed combination of Summit with Viewlogic. As has been

upon culmination of the merger. Closing of the merger is subject to customary
closing conditions, including approval of Summit's and Viewlogic's shareholders.

The Board of Directors extends its thanks to Davenport for his dedicated efforts
on behalf of Summit Design. He has helped guide the company through a range of
challenges and accomplishments. Much of the credit for Summit's successes during
