EX-99.1

SUMMIT DESIGN, INC. UPDATES STATUS OF PROPOSED ORCAD MERGER


BEAVERTON, ORE. -- DECEMBER 7, 1998 -- Summit Design, Inc. (Nasdaq: SMMT) 
today announced that it is in the process of responding to comments received 
from the Securities and Exchange Commission ("SEC") relating to its 
registration statement filed in connection with Summit's proposed acquisition 
of OrCAD, Inc.

Some of the SEC comments relate to the accounting treatment of Summit's 
acquisition of Simulation Technologies Corp. ("SimTech") in the third quarter 
of 1997.  That treatment resulted in a charge to earnings of $19.9 million in 
the third quarter of 1997.

The accounting treatment of the SimTech acquisition, including the write-off 
of in-process research and development, and the valuation of certain 
consideration paid to SimTech shareholders, was in accordance with 
established accounting practice and based upon valuations provided by 
Summit's public accountants and an independent financial advisor.  However, 
the Securities and Exchange Commission has recently provided additional 
guidance on the determination of in-process research and development 
write-offs.  In addition, the Securities and Exchange Commission has 
commented on the possible contingent nature of a portion of the consideration 
paid to SimTech shareholders.

In light of the Securities and Exchange Commission's current views, Summit 
believes that it will be required to revise the accounting treatment for the 
SimTech acquisition.  The revised accounting treatment would not impact 
Summit's cash or liquidity position.  However, such accounting treatment 
would result in a material increase in recorded intangible assets and related 
amortization expense associated with the SimTech acquisition and could affect 
the recognition of certain consideration paid to SimTech shareholders and 
would, therefore, have a material adverse impact on Summit's operating 
expenses and earnings in the quarters subsequent to the acquisition and in 
future quarters.(1)  Until the Securities and Exchange Commission's

Section 27A of the Securities Act of 1933, as amended, and Section 21E of the 
Securities Exchange Act of 1934. Summit will not know the extent to which it 
will have to revise its accounting treatment until completion of its own 
analysis and of discussions with the Securities and Exchange Commission.



comments have been resolved, Summit will not be able to quantify the extent of
the restatement of financial statements.  However, any such adjustments would be
noncash charges and would not affect Summit's cash or liquidity position.


Due to the timing of responding to comments received from the Securities and 
Exchange Commission, Summit expects that its proposed acquisition of OrCAD, 
Inc. will close in the first quarter of 1999.(2)
