          The following is a transcript of a conference call hosted jointly by
          Synopsys, Inc. and Avant! Corporation on December 3, 2001.


                        Synopsys Conference Call, 12.3.01

Operator: Ladies and Gentlemen, thank you for standing by, and welcome to
          this special conference call. At this time all participants are in a
          listen-only mode. Later we will conduct a question-and-answer session.
          Instructions will be given at that time. If you should require
          assistance during the call, please press "0," followed by "star." As a
          reminder, today's conference is being recorded.

          During the course of this conference call, Synopsys and Avant!
          (pronounced Ah-VAHN-tee) Corporation may make forward-looking
          statements regarding the performance of the companies before the
          proposed merger and the combined company after the proposed merger,
          and, in Synopsys's case, regarding the future financial result. While
          these statements represent each company's best current judgement about
          its future performance, each company's actual performance is subject
          to significant uncertainties that could cause actual results to differ
          materially from those that may be projected, including the risk
          described in the two press releases issued earlier today describing
          the proposed merger and Syopsys' fourth quarter and Fiscal Year 2001
          results. In addition to any other risk factors that may be highlighted
          during this conference call, listeners should also review each
          company's most recent 10-K, 10-Q, and 8-K reports on file with the
          Securities and Exchange Commission, as well as the [collection]
          materials that will be filed regarding the proposed merger for
          important factors that could cause actual results to differ materially
          from those that may be projected.

          At this time I would like to turn the conference over to the Chairman
          and Chief Executive Officer of Synopsys, Dr. Aart de Geus. Please go
          ahead, Sir.

    Aart
 de Geus: Good afternoon. I have with me Paul Lo, President of Avant!,
          Chi-Foon Chan, President and COO of Synopsys, and Brad Henske, our
          CFO. We have moved our earnings conference up because we have some
          great news to announce. Synopsys has signed a definitive agreement to
          acquire Avant! Corporation. This is exciting news for many reasons.

          First, for our customers, the merger instantly brings together the
          best front-end and the best back-end design tools under a single roof.
          Many top executives from the largest semiconductor and system
          companies have personally suggested to me that they would welcome such
          a move.

          Second, both Avant! and Synopsys employees see the power of this
          combination. Our employees have a tradition of strong technology
          innovation, delivery, and support. Combining expertise in our
          complementary areas opens the door to providing a complete IC design
          solution that is unmatched in the industry.

          Third, our shareholders have viewed it as a very strong move. At a
          time when customers are reducing their number of suppliers, Synopsys
          emerges as a provider of the strongest technical solution in the
          industry. In addition, both Synopsys and Avant! have a solid track
          record of sound financial execution and growth.

          The bottom line is that this merger is a bold move that instantly puts
          up in the leadership position for IC design automation.

          What everyone knows, is that Avant! has had significant legal
          troubles. I want to move forward here. Some bad things occurred, some
          people were caught, they pleaded no contest, some individuals received
          sentences and Avant! paid the price. A huge price. Not only did they
          make a very large restitution payment upon closure of the criminal
          case, but they also suffered for years under a cloud of doubt and
          distrust. This is especially unfortunate in light of the outstanding
          new technology that their engineers have produced over the years. But
          let me be very clear, we have not condoned what happened in the past.
          We have done our homework and we are convinced that what we are
          acquiring today is clean. In addition, we will put forth our best
          effort to practically seek a reasonable and fair settlement with
          Cadence on any outstanding issues effective on the closing of the
          merger. Cadence and Synopsys leadership in resolving these issues will
          open a new chapter to a more mature and healthier EDA industry going
          forward.

          This is an important time to strengthen our industry, especially in
          light of the economic situation around us. In the last three months
          the outlook for semiconductors and electronics in general have become
          significantly bleaker as hopes for an earlier recovery have been
          replaced with an almost complete lack of visibility.

          Our customers have forced to take action. After initially cutting the
          obvious things, they are now re-examining even their key projects and,
          if necessary, cutting into what was previously considered untouchable.
          Even R&D budgets are no longer immune and EDA expenses are
          increasingly scrutinized and/or delayed. I hasten to say however that
          compared to our customers our EDA industry has so far performed
          remarkably well and will continue to do so. For Synopsys, we completed
          a solid quarter and met expectations. Nonetheless, good management
          discipline clearly prescribes that we forecast more conservatively,
          that we manage expenses aggressively, and that we correct up or down
          as visibility returns. We will manage the business in fiscal '02 to
          yield earnings of at least $2.00 a share. Brad will give detail about
          that in a moment.

          No matter what the economic situation looks like, though, Synopsys as
          a company is very strong. We expect to gain market share through
          growth of the combined company as our customers reduce the number of
          their suppliers, and we will make bold moves to maximize the
          situation. From that perspective, the acquisition of Avant!
          compliments our existing position in a remarkable way.

          To explain this better let me paint a picture that describes the
          post-merger Synopsys. It is helpful to think of the IC design process
          as having three main functions: design creation, functional
          verification, and design integrity.

          Let me start with design creation. This is the process that implements
          a high-level chip description written in a language such as Verilog,
          VHDL, or C into a detailed layout. Traditionally this was done in two
          main steps. First: Synthesis; and second, Place-and-Route.

          Synopsys is clearly the technical and market leader in synthesis.
          Avant! is the strongest place-and-route solution where it competes
          most directly with Cadence, among others.

          In the last two years, driven by small geometries, a new discipline
          has emerged at the intersection between the two steps. This new
          discipline is aptly named physical synthesis. Synopsys far and away
          leads in this emerging area with over 75 percent bookings growth in
          fiscal '01 over last year, ending the year with 103 million in orders,
          well over 350 tapeouts, and over 150 customers. This does not include
          approximately 11 million in orders from customers who bought our
          design compiler product and then upgraded to physical compiler within
          the year. Those numbers will bring the tally to 114 million for
          Physical Synthesis.

          It was also rewarding to see that orders in aggregate for the design
          compiler family grew approximately 50 million this year as customers
          currently find that a mix of design compiler and physical compiler
          meets their need.

          The quality of our customer base in this area is impressive. For
          example, just last quarter we announced a variety of physical
          synthesis endorsements from IBM, TSMC, NEC, and Scientific Atlanta. I
          have no doubt whatsoever that the combination of Synopsys synthesis
          and physical synthesis with Avant!'s place and route, and database, is
          the best-in-class design flow today. More than that, it is also the
          basis for delivering leading solutions for .13 and .10 micron in a
          very short time frame.

          The second area is functional verification. The objective in this area
          is simply stated as: "Does my design perform the function that I
          intended?" meaning for example, "Does my multiplier actually
          multiply?" Since the early days of EDA, this area has been anchored by
          simulation. With VCS, our Verilog simulator, Synopsys has a star
          product. Around VCS we have half a dozen connected products ranging
          from models to testbench languages to formal verification techniques.

          Avant! adds a crucial piece to this picture: a leading circuit
          simulator. This addition significantly strengthens our competitive
          position in mixed-signal verification, which is needed for chips in
          the wireless, automotive, and consumer domains.

          The third area is "design integrity," where you make sure that the
          chip will actually work. Here you check for errors ranging from signal
          integrity to timing to manufacturing defects. Synopsys has an
          extremely strong position in this area. Our design-for-test solution
          is very well integrated into the design flow and PrimeTime is the de
          facto standard timing verifier in the industry. In addition, we have
          recently grown these capabilities with leading-edge signal integrity
          analysis.

          The Avant! acquisition fills a major hole for us in the design
          integrity arena: a complete physical verification, extraction, and
          mask synthesis solution. These terms may not mean much to the
          uninitiated, but they allow customers to verify that the chip can
          truly be fabricated and will work at the correct speed.

          Furthermore, in all the areas, design creation, functional
          verification, and design integrity, the highly regarded Milky Way
          database from Avant! will be a key asset in connecting all these
          pieces together smoothly.

          The bottom line of this is powerful. In all three areas, but
          especially in design creation and design integrity, Synopsys and
          Avant! are an almost perfect complementary match. Our customers have
          long known this and have done their best to glue our products together
          in their own flows. But coming together into one company now will
          provide a solution that fulfills the requirements of the most
          demanding designers.

          At this point I would be remiss not to mention two other highlights
          from the past quarter. It's no secret that most consulting businesses
          are feeling the brunt of the economic downturn, ours included.
          However, we continue to invest in this business, anticipating that the
          combination of tools, services, and state-of-the-art system-on-chip
          requirements will bring good business opportunities.

          Confirming that investment, we recently announced a very significant
          relationship with Intel, who is entering the ASIC business with our
          support. Together with Intel, we are offering a complete concept-to-
          manufactured-parts solutions to mutual customers. Two large contracts
          with US systems companies have already been closed.

          The second area that I would like to highlight is our intellectual
          property business. We have always believed that the reuse of IP is a
          key influencer of methodology and tools, and vice versa. As you know,
          we have a substantial DesignWare business, which up until now has
          consisted mainly of basic IP business blocks. Last quarter we
          announced agreements with ARM, MIPS, NEC, Infineon and Gain to
          distribute much of their higher level IP through our DesignWare
          channel

          To conclude this portion of the call I would like to reiterate my
          enthusiasm about the merger. And with that I would like to now turn
          the call over to Paul Lo, president of Avant!, who is here with us
          today as well.

          Paul?

    Paul: Thank you Aart. Good afternoon everyone. This is Paul, president of
          Avant!. Today for the first time I'm joining Synopsys in their
          conference call to talk about Synopsys's purchase of Avant!.

          This merger opens a new chapter in the history of the EDA industry.
          Two acknowledged industry leaders are now joining forces to form what
          we believe will soon be the pre-eminent supplier in the EDA business.
          I'm happy and proud to be a part of it and I have high hopes for the
          future.

          Although Synopsys and Avant! have built their businesses independently
          over the past several years, we have some of the same basic values.
          Both Synopsys and Avant! have always focused on technology
          development, and have pride in the technologists who created it.

          I know what it takes to create the most competitive chip design
          systems in the world. I have also observed Synopsys technology and
          product development over the years as well. I have great respect for
          Synopsys and I have come to know Synopsys as a company that knows what
          the customer wants and is persistent in delivering it. I think that
          Synopsys and Avant! are soul mates when it comes to technology
          development.

          I believe that this merger creates great value for the customers.
          Semiconductor manufacturing technology has continued to advance and
          customers have come to depend on both Synopsys and Avant! to deliver
          ever more advanced chip design solutions. Products from both Synopsys
          and Avant! are now used in the world's most advanced chip design flow.
          For years our customers have asked us to work more closely with
          Synopsys and now their wish has come true. In this combination our
          customers will get the best technology available today along with the
          best engine of innovation in the business.

          I want to take a moment to reflect on the accomplishments of Avant! as
          an independent company. Avant! began in 1991 as a supplier of standard
          sale systems. Even today customers recognize Avant! as the leader in
          this large and growing product category, but we have become much more
          since our humble beginning. We initiated and nurtured a company
          culture based on customers, technology, and people. Avant! had grown
          to offer over 45 different products including the powerful single path
          SOC design flow and Milky Way database which offers customers the most
          productive chip design process in the world.

          Avant! has also had its big challenges, but thanks to the fighting
          spirit of hundreds of Avant! employees we not only survived, but
          flourished. I think that the last six years of Avant!'s history
          illustrates the tough character and supreme determination of Avant!.
          I'm convinced that this will not be lost as we join forces with
          Synopsys.

          I have personally visited over 30 customers in the recent month. In
          all these visits not a single customer has told me that they are
          abandoning us. Instead they have high hopes for new products that we
          recently introduced. Over 90 percent of our top customers are actually
          engaged in the evaluation of one or more of our new products. We have
          strong tradition of loyalty to our R&D engineers. As a result, our
          turnover rate among this group has been very low. We bet that our team
          of technologists will be happy and proud to join Synopsys because of
          their passion for great technology.

          Overall I think that this combination creates a great new team, a team
          that I know I will be proud of. In my opinion this merger teams the
          best with the best. It is great for customers and great for the
          industry overall. I think that the merger will create the very best
          company in the EDA business.

          Thank you. Now I turn the call to Brad.

    Brad
  Henske: Thanks Paul. Aart and Paul have described some of the benefits
          of the transaction and the terrific fit between the two companies. Let
          me briefly talk about some of the details of the transaction and then
          I'll review our quarter and guidance.

          The deal itself is pretty vanilla. It's a straight stock for stock
          deal in which each Avant! share will be exchanged for .371 shares of
          Synopsys stocks at closing. There are no caps or collars. At today's
          closing price for Synopsys of $55.39, the aggregate consideration,
          based on Avant!'s fully diluted shares is approximately 830 million
          dollars. We expect to effect a tax-free reorganization. Outstanding
          Avant! options will be converted into Synopsys options at closing,
          based on the exchange ratio.

          From an operational point of view, Avant! will be integrated into
          Synopsys after closing. No Avant! board members will join the Synopsys
          board, and Gerry Hsu will resign all positions with the company
          effective on the closing date. We expect the fees and expenses at
          closing will be approximately 420 million dollars, including $335
          million for insurance--which I will talk about in a minute--$55
          million to pay pre-existing employment agreements, and 30 million
          dollars in investment banking, brokerage and other fees and expenses.
          We expect additional severance and facility consolidation expenses in
          the first operating quarter.

          In connection with the merger agreement, by December 31st Avant!'s
          Japanese distributor, Maingate, will become a wholly owned subsidiary
          of Avant! with no remaining individual shareholders at approximately
          no net cost to Avant!. Avant!'s other principal distributor agreements
          have been modified to remove the distributor's right to receive large
          lump sum payments upon a change of control. Avant! will file an 8-K
          with the SEC which will provide the details regarding these
          transactions.

          As I mentioned, we have obtained a binder of insurance, effective
          after the closing, with a triple A rated insurer to pay all damages,
          penalties, and costs arising out of the litigation with Cadence. The
          total premium will be 335 million dollars. The policy coverage limit
          is 500 million dollars plus accrued interest on the first 250 million
          dollars of the premium. In the event that amounts paid out on the
          policy are less than 250 million plus accrued interest, Synopsys will
          be entitled to a refund of the difference. While we cannot guarantee
          the outcome of the case, based on our assessment of the probabilities
          which was developed with the assistance of two outside law firms, we
          believe that we have more than adequately provided for the liability.
          For financial reporting purposes, 250 million dollars of the premium
          will be held on the Synopsys balance sheet as a long term restricted
          asset and the interest from that amount will be included in other
          income. The remaining 85 million dollars will be expensed when the
          policy takes effect. The transaction is subject to approval by both
          company shareholders, regulatory approval, and other customary closing
          conditions. While always hard to predict, we expect the deal will
          close within three to six months.

          Let me now give you the details on what was, given the environment, a
          successful fourth quarter for fiscal 2001, followed by some commentary
          on our outlook going forward and the impact of the proposed merger.

          For Q4 our revenue came in at the middle of our guidance range. We
          outperformed on expenses, and earnings before goodwill per share was
          39 cents, at the top of our target range. We also built considerable
          backlog, deferred revenue, and cash. Q4 was the highest orders quarter
          in Synopsys history. Orders in aggregate grew approximately 14 percent
          in fiscal 2001 over fiscal 2000. Q4 product orders divided between
          approximately 86 percent Technology Subscription Licenses or TSLs,
          and 14 percent perpetuals, which we believe is an abnormally low level
          and was driven by the large number of aggregate orders in the quarter.
          The average duration of TSLs in Q4 continued to be between three and
          half and four years.

          Orders linearity for Q4 was consistent with the prior quarter, and,
          while not as good as we would have liked, was still better than that
          experience prior to our license change. Q4 revenue was 183.6 million
          dollars, which represents 38 percent growth from the same quarter a
          year ago and is in the middle of our guidance range. Product revenue,
          which is primarily comprised of our perpetual licenses, was 47 million
          dollars. Ratable license revenue was 55 million dollars this quarter.
          TSL revenue continues to grow as our backlog flywheel continues to
          build. Services revenue totaled 82 million dollars this quarter, down
          six percent from the same period a year ago and flat when compared to
          last quarter. We continue to see the migration of the old TBL
          maintenance into the TSL revenue screen.

          Overall gross margin was 81 percent of revenue, flat when compared to
          the prior quarter. Product gross margin was 91 percent for Q4-01
          compared to 85 percent for the prior quarter. Ratable license gross
          margins equaled 82 percent for Q4 as compared to 87 percent for Q3.

          We have started this quarter to allocate product cost-of-goods based
          on product order mix rather than product revenue mix as we had in
          prior quarters. This will be effective for all of fiscal 2001. The
          aggregate cost-of-goods is unchanged. The change in margins from Q3 to
          Q4 was driven by the large increase in TSL orders in proportion to
          revenue in our seasonally strongest quarter of the year. Service gross
          margins came in at 76 percent, flat as compared to the prior quarter.

          Our aggregate EBG operating expenses, including cost-of-goods, were
          166 million dollars, at the bottom of our guidance range. Operating
          earnings were 17.6 million, up 198 percent sequentially. Other income
          was 17 million, and investment gains were 13.5 million, in line with
          expectations. Earnings before goodwill amounted to 39 cents per share,
          at the upper end of our guidance based on lower expenses. Diluted
          share count was 62 and a half million, slightly below expectations, as
          our stock price was somewhat lower throughout the quarter than we
          expected.

          Synopsys's balance sheet is strengthening. Cash and short-term
          investments grew substantially, with our Q4 balance ending at 476
          million dollars, up 167 million dollars from the prior quarter. Q4
          cash per diluted share amounted to seven dollars and 63 cents. Q4
          accounts receivable totaled 146 million dollars. For the quarter, DSO
          was 73 days, up from 68 days in Q3. During the quarter we factored no
          receivables. Deferred revenue at the end of the quarter was 380
          million dollars, up 129 million dollars or 51 percent from the prior
          quarter.

          During the quarter we repurchased no shares under our stock buyback
          program. As a result of our discussions with Avant!, we closed the
          trading window for both the buyback and company management. We'll
          resume stock purchases in this quarter to the extent that we find
          market conditions attractive, while at the same time planning for
          funding the payments at closing of the Avant! acquisition. Head count
          totaled 3,308 employees for the quarter, up 106 from the prior
          quarter.

          Now I'd like to spend a minute discussing the current economic
          environment and the impact it's having on our business. As Aart
          mentioned, we completed our quarter against the backdrop of a steadily
          deteriorating economic environment. The semiconductor industry
          continues to be mired in a downturn that if measured by peak-to-trough
          of shipments is almost twice as bad as any downturn in the last 15
          years. As revenue has fallen semiconductor R&D spending as a
          percentage of revenue has increased. It has now reached levels not
          seen in recent history. Perhaps most striking, very few of our
          customers will say they have much visibility into the next few
          quarters. As a result, in the last quarter customers hit the brakes,
          hard. Therefore both visibility and predictability of business has
          abruptly gotten a lot poorer for us, and we believe in reality for the
          rest of the EDA industry.

          For us, on the positive side, we have continued to book significant
          contracts with both large and small customers, including in this
          quarter the largest single contract in Synopsys history. Our
          transition to a ratable model has been largely successful, and we end
          our fiscal year 2002 with 432 million dollars in deferred revenue and
          backlog that will turn into revenue this year.

          We're seeing customers starting to pare down their list of suppliers
          and we are clearly on the A list.

          But not even players on the A list are going to get through this
          recession unscathed. During the quarter we saw a number of trends in
          the business relating to the recession that caused us to take a more
          cautious outlook going forward.

          First, our consulting and training business continues to struggle,
          reflecting the environment. Orders, although strong in Q3, were
          relatively weak in Q4, causing us to move our expectations for the
          consulting business's revenue down by more than 24 million dollars in
          fiscal 2002. During Q4 the average duration of TSLs was longer than we
          expected. On the positive side, the customers are willing to commit to
          our technology for longer terms. It also builds long term backlog,
          which is now ahead where we assumed it would be. For the short term,
          however, the TSLs booked in Q4 will deliver less revenue in the next
          12 months than we originally expected. As the realities of the market
          became more apparent, we began to focus on a more conservative plan,
          to tighten our own spending, to curtail hiring and other expenses,
          thus bringing our operating expenses in at the bottom of our range.

          Let me come now to future guidance. In light of the changes in the
          economic environment and with the potential impact of the merger with
          Avant!, we do not believe that we have enough visibility to
          confidently give complete guidance for 2002.

          However, for the first fiscal quarter of 2002 we expect revenue of 174
          to 178 million, total expenses of 162 to 166 million, other income and
          expense of ten to 11 million including approximately seven million
          dollars of investment gains, outstanding shares of 63 to 65 million,
          and earnings before goodwill of 24 to 28 cents per share.

          We expect revenue to consist of approximately 20 percent perpetuals,
          40 percent ratable revenue, and 40 percent services. Total revenue
          will be down sequentially from Q4 as we expect approximately 11
          million dollars less product revenue from perpetuals in Q1 than in Q4.
          At this stage in our transition of ratable revenue, orders for
          perpetuals still have a disproportionate impact on total revenue, and
          Q1 is historically our lowest bookings quarter. In addition, we expect
          other I & E to be down by approximately seven million dollars based on
          the planned lower gain on sales and investments. The impact of these
          changes, offset by lower expenses, will produce the sequentially lower
          earnings.

          On the positive side, however, our forecast for Q1 is slightly higher
          than the forecast that we held three months ago at the end of Q3 2001.
          Without sufficient visibility for the full year at this stage, we are
          modifying our full year 2002 guidance that we gave at the end of Q3 in
          a number of significant respects. In light of the current environment,
          we have decided to manage our business to deliver specific earnings
          for the year, namely, at least two dollars per share on an EBG basis.

          Revenue will be lower than the guidance we provided at the end of Q3,
          but at this time we are not providing updated revenue guidance for the
          year and are withdrawing our previous guidance. We are acting
          immediately to reduce our expected expenses in 2002 by 30 million
          dollars versus the guidance given before, and will reduce expenses
          further if necessary to meet our earnings target. While it's possible
          for one to infer a revenue number from the guidance we've provided,
          any such calculations should not be construed as guidance from us.

          We'll reconsider this decision at the end of each quarter and should
          conditions change sufficiently we will issue revenue guidance. We
          expect other I & E, the tax rate and outstanding shares to be
          consistent with prior guidance. Although we appreciate that our
          guidance is lower and less certain than the guidance we issued three
          month ago, we feel it reflects reality in the EDA markets today. For
          the year, we expect orders to grow modestly, on the rough order of ten
          percent depending on changes in the economy, and assuming a three year
          average TSL duration. We expect perpetuals to be 15 to 25 percent of
          orders in any given quarter. We are broadening the range a bit from
          last quarter's guidance in view of the volatility of the market.

          None of the foregoing discussion reflects the proposed acquisition of
          Avant!. Highly dependent on the timing of the closing, we expect that
          the acquisition will be modestly dilutive in fiscal 2001, on the rough
          order of 30 cents. This is primarily driven by the conversion of their
          business to our license mix and the accounting difficulty in
          recognizing in the future the deferred revenue and backlog that Avant!
          will have closing. But for these effects we expect the acquisition of
          Avant! would be significantly accretive in the short term.

          As we have previously announced Avant! today books approximately 50
          percent of its orders as perpetual licenses and 50 percent as
          subscriptions. We expect that the customer dynamics of an integrated
          company will rapidly move that to the Synopsys mix. Similar to the
          effect of our business change a year ago, the mix change will depress
          reported earnings from the "Avant!" orders in the short term. In
          addition, the rules of purchase accounting for software companies make
          it difficult to bring across the deferred revenue and backlog for
          ratable licenses, since the future direct "cost to perform" is not
          clear. This is an issue that we're currently discussing with the
          Emerging Issues Task Force of the FASB and the SEC. It does not impact
          the economic substance of this deal since we will still get the cash
          payments and still provide the appropriate services. However, we may
          not be able to recognize revenue for this backlog which will affect
          both reported revenue and earnings. Based on the forecast we have
          today, the net impact of both of these things is on the rough order of
          a dollar per share of EBG, which would make the deal significantly
          accretive in the short term. In any case, it will be significantly
          accretive in the long term. As has been our practice, we will give
          more quantitative specifics around the closing. And again as a
          reminder, none of these forecasts include the effect of the closing of
          the IKOS acquisition, which is expected to occur sometime in Q4 of
          2002.

          Thank you for your attention. I'll now turn it back to Aart for his
          closing comments.

    Aart
 de Geus: Thank you Brad and Paul.

          In conclusion let me just review the basis for my excitement about our
          acquisition of Avant! which is threefold. First, it brings together
          the best front-end technology with the best back-end technology,
          resulting in the strongest design solution today. Second, it fulfills
          a request that our customers have made for years and they are thrilled
          that we are finally merging. And last, in a tough economic climate
          winners make bold moves and we believe that we just made such a
          winning move.

          Thank you for your attention. Let's now open up for Q and A. Operator,
          please poll for questions.
