                Synopsys Expects Second Quarter Fiscal Year 2002
                      Earnings and Revenue Above Estimates

MOUNTAIN VIEW, California. May 6, 2002 - Synopsys Inc., (Nasdaq: SNPS), the
technology leader for complex integrated circuit design, today announced
preliminary revenue and earnings before goodwill (EBG) results for the second
quarter of fiscal year 2002, which ended on Saturday, May 4, 2002.

Synopsys announced that it expects second quarter fiscal year 2002 EBG to be
approximately $0.38 per share, two cents per share above the First Call(R)
consensus estimate of $0.36 per share, and that it expects revenue for the
quarter to be approximately $185 - $186 million, approximately $1 million above
the consensus estimate. EBG represents earnings on a diluted basis excluding
amortization of intangible assets and in-process research and development.

Orders meaningfully exceeded the Company's expectations for the quarter,
increasing approximately 20% over the second quarter of fiscal year 2001 and
approximately 85% over the first quarter of fiscal year 2002. Orders for
perpetual licenses were approximately 21%-22% of total software orders, within
the anticipated range for the quarter.

"This was a very good quarter for us, though the market remains difficult and
the electronics industry continues to struggle," said Aart de Geus, Chairman and
Chief Executive Officer of Synopsys. "Even in uncertain economic times,
customers continue to invest in design technologies and buy from their critical
technology partners, and our physical synthesis products enjoyed their best
quarter ever. We are excited to be heading towards the completion of our merger
with Avant!, and the realization of our vision of bringing together the best
front end and the best back end design tools in the industry. Based on our
results, and the record revenue and earnings announced last week by Avant!, we
believe that the combined company will have strong product and financial
momentum from day one."

In connection with the merger, Synopsys indicated that it expected to recognize
as revenue approximately 70-80% of Avant!'s aggregate deferred revenue and
backlog, assuming fulfillment by the combined company of the commitments
represented by such deferred revenue and backlog. Avant!'s aggregate deferred
revenue and backlog will be determined at closing; revenue will be recognized as
products and services are delivered and payments become due. Synopsys further
noted that its proposed accounting treatment of deferred revenue and backlog had
been confirmed by the Securities and Exchange Commission. Detailed financial
guidance for the combined company will be provided after the close of the
merger; both companies' shareholder meetings are scheduled for June 4, 2002.

Synopsys cautioned that these anticipated results are preliminary, based on the
best information currently available, and are subject to the closing of its
books and customary quarterly accounting procedures.
