MANAGEMENT'S DISCUSSION AND ANALYSIS              
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS            
               
OVERVIEW            


Quickturn Design Systems, Inc. (the "Company") designs, manufactures, sells 
and supports products that provide system-level verification solutions for 
the design of integrated circuits and electronic systems.  The Company 
currently derives a substantial majority of its revenue from its System  
Realizer product and related maintenance and consulting services. Quickturn's 
products serve the  needs of IC and systems design engineers in a variety of 
markets including computers, workstations  and PCs, telecommunications, 
semiconductor,  microprocesser and multimedia graphics. The Company  began 
operations in 1987 and commenced shipments in 1989. In 1996, the Company 
introduced two  new software products, Quest II and HDL-ICE 2.0 to enable 
customers to more quickly and easily  compile their IC designs.  

On February 7, 1997, the Company acquired SpeedSim, Inc. ("SpeedSim"), a 
provider of cycle-based  simulation software for the verification of digital 
logic designs (the "SpeedSim Merger") for 2.8 million  shares of Quickturn 
common stock. The acquisition was accounted for as a pooling of interests. 
The  Company estimates that it will incur direct transaction costs of at 
least $1.2 million associated with the  acquisition, which will be charged to 
operations during the quarter ending March 31, 1997.  See Note  15 of the 
Notes to Consolidated Financial Statements.

TOTAL REVENUE       
Total revenue increased by $22.6 million, or 28%, to $104.4 million in 1996 
over 1995 compared with an increase of $16.3 million, or 25%, in 1995 over 
1994. The total revenue growth in both 1996 and  1995 was primarily 
attributable to increased sales of greater emulation capacity. System 
Realizer  product revenue accounted for 71% and 66% of total revenue in 1996 
and 1995, respectively, while previous generation emulation products 
accounted for 65% of total revenue in 1994. Maintenance  revenue for all 
products accounted for 16%, 14% and 13% of total revenue in 1996, 1995 and 
1994,  respectively.  On a price per logic gate basis, both product costs and 
the average price for an emulation  system with equivalent capacity decreased 
due to increased efficiency of reprogrammable system  components and lower 
component costs.   


                                        18
  



Domestic revenue (North American sales) grew by 17%, 15% and 19%, while 
international revenue  grew by 50%, 52% and 21% in 1996, 1995 and 1994, 
respectively.  International sales accounted for  approximately 37%, 31% and 
26% of total revenue in 1996, 1995 and 1994, respectively. The increase  in 
international sales was largely due to revenue growth in the Asia-Pacific 
markets, which increased  by 82% to $29.9 million in 1996, and by 76% to 
$16.4 million in 1995. Revenue from most  international customers is 
denominated in U.S. dollars. However, receivables from certain other  
international customers are denominated in local currencies. Such receivables 
are hedged, where  practicable, by forward exchange contracts to minimize the 
impact of foreign exchange rate  movements on the Company's operating 
results.  See Note 2 of the Notes to Consolidated Financial  Statements.  
There can be no assurance that fluctuations in the currency exchange rates in 
the future  will not have a material adverse impact on the receivables 
derived from foreign currency denominated  sales and thus the Company's 
operating results and financial condition.  
  
Many of the Company's customers order on an as-needed basis and often delay 
delivery of firm  purchase orders until the commencement dates of such 
customers' development projects are  determined. Moreover, a significant 
portion of the Company's total revenue in each quarter generally  results 
from shipments in the last few weeks of the quarter; therefore, a delay in 
the shipment of a few  orders can have a significant impact upon total 
revenue and results of operations in a given quarter.          
          
A relatively limited number of customers have historically accounted for a 
substantial portion of the Company's revenue. These customers represent early 
adopters of emulation technology, typically for the design of complex 
integrated circuits. In particular, the Company's top ten customers 
represented 51%, 48% and 46% of total revenue in 1996, 1995 and 1994, 
respectively. One customer, Fujitsu, comprised 13% of the Company's total 
revenue in 1996, and no customer individually comprised more than 10% of the 
Company's total revenue in 1995 and 1994. The Company expects that sales of 
its products to a relatively limited number of customers will continue to 
account for a high percentage of revenue for the foreseeable future.  The 
loss of a major customer or any reduction in orders by such a customer could 
have an adverse effect on the Company's financial condition or results of 
operations.          
          
The Company believes that in the future its results of operations in a 
quarterly period could be impacted by the timing of customer development 
projects and related purchase orders for the Company's emulation systems, new 
product announcements and releases by the Company, and economic conditions 
generally and in the electronics industry specifically.         
          
The Company recognizes revenue from sales of its emulation products and 
services when all 






substantial conditions have been met, including shipment to the customer, 
fulfillment of acceptance terms, if any, and completion of all significant 
contractual terms. Maintenance revenue is deferred and recognized ratably 
over the term of the maintenance agreement, which is typically twelve months. 
Maintenance contracts are typically renewed annually.  Warranty and 
similar costs related to post-contract customer support are accrued at the 
time of sale. 
          
          
GROSS MARGINS       
Cost of revenue includes materials, labor and overhead incurred in the 
manufacture of emulation systems as well as the cost of providing service and 
maintenance. Gross margins were approximately 69% of total revenue in each of 
the fiscal years 1996, 1995 and 1994.  The Company was able to maintain its 
gross margins primarily due to a sufficiently large revenue base over which 
to spread fixed costs, and to continued manufacturing efficiencies, somewhat 
offset by a decreasing average price per logic gate. The Company expects 
competitive pressures to increase in its market from existing companies and 
new entrants, which among other things could accelerate the trend of such 
decreasing average price per logic gate.  Accordingly, there can be no 
assurance that the Company will be able to sustain its recent gross margins.  
Furthermore, to the extent that the Company's cost reduction goals are 
achieved, any resulting cost savings that are passed on to the Company's 
customers may also have an adverse effect on gross margins.

RESEARCH AND DEVELOPMENT           
Research and development expenses increased to $18.5 million in 1996 compared 
to $14.9 million in 1995 and $12.4 million in 1994.  These increases were 
primarily attributable to increased staffing and equipment costs necessary to 
enhance current products and research and development activities for the next 
generation emulation products.  Research and development expenses as a 
percentage of total revenue were approximately 18%, 18% and 19% in 1996, 1995 
and 1994, respectively. The Company expects to continue to invest a 
significant amount of its resources in research and development.


                                        19



SALES AND MARKETING
Sales and marketing expenses were $30.7 million in 1996 compared to $25.4 
million in 1995 and $21.2 million in 1994. Sales and marketing expenses 
increased in each period due to the expansion of the Company's marketing and 
sales organizations and higher sales commissions associated with increased 
revenue. As a percentage of total revenue, sales and marketing expenses were 
approximately 29%, 31% and 32% in 1996, 1995 and 1994, respectively. The 
Company expects that sales and marketing expenses will continue to increase 
in absolute dollar amounts as the Company expands its sales and marketing 
efforts.

GENERAL AND ADMINISTRATIVE
General and administrative expenses were $6.5 million in 1996 compared to 
$4.7 million in 1995 and $7.6 million in 1994. The increase in general and 
administrative expenses in 1996 was primarily attributable to increased legal 
costs related to a patent infringement lawsuit filed by the Company in 
January 1996.  See Note 14 of the Notes to Consolidated Financial Statements. 
The Company expects general and administrative expenses to increase in 1997 
due primarily to continued legal costs associated with the lawsuit. General 
and administrative expenses in 1994 included a $3.7 million write-off for bad 
debts, consisting of a one-time charge attributed to two customers that 
advised the Company in the quarter ended December 31, 1994 of their inability 
to meet financial obligations.  See Note 2 of the Notes to Consolidated 
Financial Statements.  General and administrative expenses represented 
approximately 6%, 6% and 12% of total revenue in 1996, 1995 and 1994, 
respectively.





OTHER INCOME AND EXPENSE
Interest income increased by $392,000 in 1996 over 1995 due primarily to a 
greater average balance of cash and cash equivalents and marketable 
securities. Interest expenses decreased $316,000 in 1996 over 1995 due to the 
payoff of lease lines used to purchase certain fixed assets and the reduction 
of other debt.
          
PROVISION FOR INCOME TAXES         
The provision for federal, state and foreign income taxes was an expense of 
$5.4 million in 1996, a benefit of $612,000 in 1995 and an expense of 
$401,000 in 1994, representing effective tax rates of 30%, (4.9%) and 8%, 
respectively.  The effective income tax rate in each year was impacted by a 
reduction in the Company's valuation allowance against deferred tax assets of 
$1.6 million, $6.8 million and $1.1 million for 1996, 1995 and 1994, 
respectively.  The effective tax rate was also reduced by the tax benefit 
from the Company's foreign sales corporation in 1996 and 1995, and by 
utilization of federal and state tax credits in all years.

At December 31, 1996, the Company had federal net operating loss 
carryforwards of $2.1 million and federal and state tax credit carryforwards 
of $300,000 and $50,000, respectively. A significant portion of the Company's 
net operating loss and tax credit carryforwards were acquired in a merger and 
are subject to an annual limitation of approximately $1.2 million.         

FACTORS AFFECTING OPERATING RESULTS          
COMPETITION         
The EDA industry is highly competitive and rapidly changing. The Company 
faces  significant competition for emulation-based system-level verification, 
in addition to competition from traditional design verification methodologies 
which rely on the approach of building and then testing complete system 
prototypes. Because of customers' requirements for a design verification 
methodology which reduces the number of costly design iterations and improves 
product quality, the Company expects competition in the market for 
system-level verification to increase as other companies attempt to introduce 
emulation products and product enhancements. Moreover, the Company competes 
with companies that have significantly greater financial, technical and 
marketing resources, greater name recognition and larger installed bases than 
the Company.  In addition, many of these competitors have established 
relationships with current and potential customers of the Company.  Increased 
competition could result in price reductions, reduced margins and loss of 
market share, all of which could materially adversely affect the Company.  
The Company believes that the principal competitive factors in the EDA market 
are 


                                        20



quality of results, the mission-critical nature of the technology, technical 
support, product performance, reputation, price and support of industry 
standards. The Company believes that it currently competes favorably with 
respect to these factors. However, there can be no assurance that the Company 
will be able to compete successfully against current and future competitors 
or that competitive pressures faced by the Company will not materially 
adversely affect its business, operating results and financial condition.     
  
          
In addition, competitors may resort to litigation as a means of competition. 
Such litigation may result in substantial costs to the Company and 
significant diversion of management time. In 1995, Mentor Graphics 
Corporation ("Mentor")  filed suit against the Company for declaratory 
judgment of noninfringement, invalidity and unenforceability of several of 
the Company's patents.  Six of the Company's patents are now involved in the 
disputes and the Company has filed counterclaims against Mentor and Mentor's 
French subsidiary, Meta Systems ("Meta"), for infringement and threatened 





infringement of those six patents.  Furthermore, in January 1996, the Company 
filed a complaint with the International Trade Commission, seeking to stop 
unfair importation of hardware logic emulation systems manufactured by Meta 
on the grounds that such systems infringe the Company's patents.  See Note 14 
of the Notes to Consolidated Financial Statements. Although patent and 
intellectual property disputes in the EDA industry are often settled through 
licensing, cross-licensing or similar arrangements, costs associated with 
such litigation and arrangements may be substantial.
          
RISKS ASSOCIATED WITH THE SPEEDSIM MERGER         
On February 7, 1997, the Company completed the SpeedSim Merger. There can be 
no assurance that the Company will not incur additional charges in subsequent 
quarters to reflect costs associated with the SpeedSim Merger or that 
management will be successful in its efforts to integrate the operations of 
the acquired company. Although the Company believes the SpeedSim Merger is in 
the best interest of the Company and its stockholders, there are significant 
risks associated with these transactions, including but not limited to: (i) 
difficulties in the integration of SpeedSim, (ii) difficulties in maintaining 
revenue levels during product transitions, (iii) difficulties or delays in 
achieving product and technology integration benefits, and (iv) increased 
competition from other software companies.  Moreover, SpeedSim is a company 
in the early stages of development. As a result, the Company believes that 
the increases in operating expenses associated with the development and 
integration of these new technologies will, in the near term, greatly exceed 
any associated increases in revenue which will have an adverse impact on 
operating results.

OTHER FACTORS
Other factors which could adversely affect the Company's quarterly operating 
results in the future include efficiencies as they relate to managing 
inventories and fixed assets, the timing of expenditures in anticipation of 
increased sales, customer product delivery requirements and shortages of 
components or labor.  Moreover, a significant portion of the Company's total 
revenue in each quarter generally results from shipments in the last few 
weeks of the quarter; therefore, a delay in the shipment of a few orders can 
have a significant impact upon total revenue and results of operations in a 
given quarter. Additionally, as a significant portion of the Company's 
revenue and net income may come from international operations, fluctuations 
of the U.S. dollar against foreign currencies and the seasonality of 
Asia-Pacific, European and other international markets could impact the 
Company's results of operations and financial condition in a particular 
quarter.
          
Due to the factors above, the Company's future earnings and stock price may 
be subject to significant volatility, particularly on a quarterly basis.  Any 
shortfall in total revenue or earnings from levels expected by securities 
analysts has had and could in the future have an immediate and significant 
adverse effect on the trading price of the Company's common stock. 
Additionally, the Company may not learn of such shortfalls until late in a 
fiscal quarter, which could result in an even more immediate and adverse 
effect on the trading price of the Company's common stock.
          
LIQUIDITY AND CAPITAL RESOURCES         
As of December 31, 1996, the Company had $52.4 million in cash, cash 
equivalents and marketable securities.  Additionally, the Company had $9.8 
million in unsecured revolving bank lines of credit. To date, no funds have 
been drawn from the bank lines of credit. The Company's credit agreements 
contain certain affirmative and restrictive covenants that are typical of 
such commercial lending arrangements. The agreements require, among other 
things, that the Company maintain a stipulated tangible net worth, meet 
certain financial ratios (quick asset to current liability and debt to 
tangible net 





worth), achieve annual profitability targets and maintain quarterly debt 
service.  The agreements also prohibit, among other things, the Company from 
paying cash dividends. See Note 7 of the Notes to Consolidated Financial 
Statements.

                                        21




Net cash provided by operating activities was $20.9 million in 1996, $10.9 
million in 1995 and $2.7 million in 1994. The increase in cash provided by 
operating activities in 1996 as compared to 1995 was primarily attributable 
to an increase in deferred revenue and a significantly smaller increase in 
deferred income taxes offset by an increase in inventories.  Additionally, 
the increase in cash provided by operations in 1995 as compared to 1994 was 
primarily attributable to greater net income from operations and a 
significantly smaller increase in accounts receivable and inventories in 1995 
compared to the increase in accounts receivable and inventories in 1994, 
offset by a decrease in accounts payable and accrued liabilities in 1995 
compared to an increase in accounts payable and accrued liabilities in 1994.
          
Net cash used in investing activities was $13.4 million in 1996, as compared 
with $500,000 provided by investing activities in 1995, and $32.4 million 
used in investing activities in 1994.  Net cash used in investing activities 
was related primarily to net purchases of marketable securities, and to 
acquisitions of property and equipment. The Company expects that investment 
levels and net cash used in investing activities will increase in future 
periods.

Capital expenditures, including capital leases, were approximately $6.2 
million, $7.7 million and $9.3 million in 1996, 1995 and 1994, respectively.  
These expenditures were primarily for the expansion of production capacity 
and the addition of research and development equipment. While the Company has 
no material capital commitments, the Company anticipates that its planned 
purchases of capital equipment in 1997 will require additional expenditures 
of approximately $11.0 million, a portion of which may be financed with cash 
and a portion of which may be financed through capital leases.

The Company believes that its current cash and cash equivalents, together 
with its existing credit facility and the cash flows expected to be generated 
by operations, will be sufficient to meet its anticipated cash needs for 
working capital, capital expenditures and marketing expansion through at 
least 1997.  Thereafter, if cash generated from operations is insufficient to 
satisfy the Company's liquidity requirements, the Company may sell additional 
equity or debt securities or obtain additional credit facilities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
 
1  BUSINESS OF THE COMPANY            
 
Quickturn Design Systems, Inc. (the "Company") designs, manufactures, sells 
and supports system-level verification solutions for the design of integrated 
circuits and electronic systems.  The Company's development and manufacturing 
facilities are located in Mountain View, California.  The Company's principal 
markets are in North America, Asia-Pacific and Europe.           
 
2  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES             
 
FINANCIAL STATEMENT PRESENTATION             
The consolidated financial statements include the accounts of the Company and 
its wholly-owned subsidiaries.  All significant intercompany accounts and 
transactions have been eliminated. 
 
USE OF ESTIMATES              
The preparation of financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amount of assets and disclosure of contingent assets 
and liabilities at the date of the financial  statements and the reported 
amounts of revenue and expenses during the reported period. Actual results 
could differ from those estimates.
 
CERTAIN RISKS AND CONCENTRATIONS             
The Company's products are concentrated in the electronic design automation 
industry which is highly competitive and rapidly changing.  Revenue is 
concentrated with a relatively limited number of customers, and supplies for 
certain components are concentrated among a few providers.  The loss of a 
major customer or any reduction in orders by such a customer, the 
interruption of certain supplier relationships, significant technological 
changes in the industry or customer requirements, the infringement or 
expropriation of proprietary intellectual property rights or patents, or the 
emergence of a major direct competitor could affect operating results 
adversely.  In addition, a significant portion of the Company's revenue is 
derived from international sales; therefore, fluctuations of the U.S. dollar 
against foreign currencies or local economic conditions could adversely 
affect operating results.
 
All marketable securities are classified as available-for-sale and are 
carried at fair value.  Unrealized gains and losses on marketable securities 
classified as available-for-sale, when material, are reported as a separate 
component of stockholders' equity.  Realized gains and losses on sales of all 
such investments are reported in earnings and computed using the specific 
identification cost method.
 
Financial instruments which potentially subject the Company to a 
concentration of credit risk principally consist of cash and cash 
equivalents, marketable securities and accounts receivable.


                                


The Company sells products to companies in the electronics industry in North 
America, Asia-Pacific and Europe.  To reduce credit risk, management performs 
ongoing credit evaluations of its customers' financial condition.  The 
Company maintains reserves for potential credit losses on its trade accounts 
receivable which are uncollateralized. Historically, except for the quarter 
ended December 31, 1994, the Company has not experienced any significant 
losses related to individual customers or groups of customers in any 
particular industry or geographic area.  In addition to the increase of 
reserves for doubtful accounts, the Company recorded a $3.7 million write-off 
of bad debts related to two customers in the quarter ended December 31, 1994.
 
The Company maintains its excess cash balances in a variety of financial 
instruments such as money market securities in various financial institutions 
and securities backed by the United States government.  The Company has not 
experienced any material losses in any of the instruments it has used for 
excess cash balances.
 
The Company enters into foreign exchange forward contracts to hedge certain 
foreign currency denominated receivable balances against changes in foreign 
currency exchange rates.  Gains and losses on the contracts are included 
together with the gains or losses from revaluation of the related 
receivables.  These contracts require the Company to exchange foreign 
currencies for U.S. dollars and generally mature within six months.  At 
December 31, 1996, the Company had forward exchange contracts outstanding 
with a notional value of $2,597,000 and an estimated fair value of $2,602,000.
 
TRANSLATION OF FOREIGN CURRENCIES            
The Company's foreign consolidated subsidiaries are considered to be 
extensions of the U.S. operation and the functional currency of the 
subsidiaries is the U.S. dollar. Accordingly, foreign entities translate 
monetary assets and liabilities at year-end exchange rates while 

                                        27



nonmonetary items are translated at historical rates. Translation gains and 
losses related to these subsidiaries are included in income. Income and 
expense accounts are translated at the average rates in effect during the 
year, except for depreciation and cost of revenue which are translated at 
historical rates.
 
REVENUE RECOGNITION           
The Company recognizes revenue from sales of its emulation products and 
services when all substantial conditions have been met, including shipment to 
the customer, fulfillment of acceptance terms, if any, and completion of all 
significant contractual terms. Maintenance revenue is deferred and recognized 
ratably over the term of the maintenance agreement, which is typically twelve 
months. Maintenance contracts are typically renewed annually.  Warranty and 
similar costs related to post-contract customer support are accrued at the 
time of sale.
 
RESEARCH AND DEVELOPMENT           
Research and development expenses are charged to operations as incurred.




 
CASH EQUIVALENTS              
Investments and deposits with original maturities of three months or less at 
the date of purchase are considered to be cash equivalents.             
 
FAIR VALUE OF FINANCIAL INSTRUMENTS               
Carrying amounts of certain of the Company's financial instruments including 
cash and cash equivalents, accounts receivable, accounts payable and other 
accrued liabilities approximate fair value due to their short maturities.  
Based on borrowing rates currently available to the Company for loans with 
similar terms, the carrying value of the note payable and capital lease 
obligations approximates fair value. Estimated fair values for marketable 
securities (See Note 3) and forward exchange contracts (see Certain Risks and 
Concentrations, above) are based on quoted market prices for the same or 
similar instruments.
 
INVENTORIES              
Inventories are stated at the lower of cost (first-in, first-out method) or 
market. The Company's inventories include high technology parts and 
components that may be specialized in nature or subject to rapid 
technological obsolescence. While the Company has programs to minimize the 
required inventories on hand and considers technological obsolescence when 
estimating required reserves to reduce recorded amounts to market values, it 
is reasonably possible that such estimates could change in the near term.
 
DEPRECIATION AND AMORTIZATION           
Fixed assets are stated at cost and are depreciated on a straight-line method 
over the estimated useful lives of the assets, typically one to five years.  
Leasehold improvements are amortized on a straight-line method over the 
shorter of the remaining lease term or the estimated useful life of the 
asset, typically three to five years.  Amortization of equipment under 
capital leases is computed using the straight-line method over the shorter of 
the remaining lease term or the estimated useful life of the related asset, 
typically three to five years.
 
ACCRUED WARRANTY              
The Company provides an accrual for future warranty costs based on the 
historical relationship of revenue to warranty costs incurred.
 
RECLASSIFICATION              
Certain amounts in the financial statements have been reclassified to conform 
with the current year's presentation.  These reclassifications had no impact 
on previously reported working capital, operating income or net income.       
     
INCOME TAXES             
The Company provides for income taxes under the liability method in 
accordance with Statement of Financial Accounting Standards No.109, (SFAS 
109), "Accounting for Income Taxes."  Under this method, deferred tax assets 
and liabilities are determined based on differences between financial 
reporting and tax bases of assets and liabilities, measured at the tax rates 
that will be in effect when the differences are expected to reverse. 
Valuation allowances are established when necessary to reduce deferred tax 
assets to the amounts expected to be realized.
 

                                


NET INCOME PER SHARE               
Net income per share is calculated using the weighted average number of 
common and dilutive common equivalent shares outstanding during the period. 
Dilutive common equivalent shares consist of common stock issuable upon 
exercise of stock options and warrants (using the treasury stock method).
 
FISCAL YEAR-END               
Since 1995, for  purposes of presentation, the Company has indicated that its 
fiscal year ends on December 31,  although the Company operates on a 52-week 
or 53-week fiscal year, ending on the last Sunday in December.  Both 1995 and 
1996 were 52-week years.

1996). The agreements are subject to certain restrictive covenants which 
include achieving annual profitability, and meeting certain financial ratios 
and minimum tangible net worth requirements. The agreements also prohibit the 
payment of cash dividends. To date, no funds have been drawn against the 
lines of credit.

STOCK OPTION PLANS       
As of December 31, 1996 the Company has reserved 3,723,713 common shares for 
issuance under various stock option plans.  Except for the 1994 Outside 
Director Stock Option Plan, which provides for automatic grants to 
non-employee directors, the Board of Directors may, under these plans, issue 
incentive stock options to employees and nonstatutory stock options to 
employees or paid consultants of the Company at prices no less than fair 
market value for incentive and  85% of fair market value for nonstatutory 
stock options.  The options are exercisable at times and in increments as 
specified by the Board of Directors.  Options generally vest over four years 
and expire ten years from date of grant. Options are exercisable prior to 
vesting, however such unvested shares are subject to repurchase by the 
Company at their original cost.  At December 31, 1996, there were 375 shares 
subject to repurchase.

of the fair market value of the Company's common stock at either the first 
day of an offering period or the last day of such offering period.  Shares 
issued under the ESPP in 1996, 1995 and 1994 were 198,117, 158,488 and 87,360 
respectively.

At December 31, 1996  and 1995, vested options to purchase 1,183,030 and 
1,016,615 shares respectively were unexercised.        
          
In July 1994, the Board of Directors offered to all employees the opportunity 
to cancel outstanding stock options with exercise prices in excess of $6.13 
per share (the fair market value of the common stock at that time) in 
exchange for options exercisable at $6.13 per share which were otherwise 
identical to the cancelled options except for a one-year extension of the 
original vesting term.  Options to purchase 562,025 shares of common stock at 
original exercise prices ranging from $8.00 to $14.75 per share were 
exchanged and are included above as 1994 grants and terminations.

The following information concerning the Company's stock option and employee 
stock purchase plans is provided in accordance with SFAS No. 123, "Accounting 
for Stock-Based Compensation."  The Company accounts for such plans in 
accordance with APB No. 25 and related interpretations. 
          
The fair value of each option grant has been estimated on the date of grant 
using the Black-Scholes option pricing model with the following weighted 
average assumptions used for grants in 1996 and 1995: 
          
                                  Group A        Group B            
                               -------------   -----------
Risk-free interest rates           6.30%          6.22%               
Expected life                     5 years        4 years             
Volatility                         0.70           0.70           
Dividend yield                      ---            ---            

The weighted average expected life was calculated based on the exercise 
behavior of each group.  Group A represents officers and directors who are a 
smaller group holding a greater average number of options than other option 
holders and who tend to exercise later in the vesting period.  Group B 
represents all other option holders, virtually all of whom are employees. 
This group tends to exercise earlier in the vesting period. 
          
The weighted average fair value of those options granted in 1996 and 1995 was 
$7.73 and $5.18, respectively. 



The Company has also estimated the fair value for the purchase rights issued 
under the Company's Employee Stock Purchase Plan, under the Black-Scholes 
valuation model using the following assumptions for 1996 and 1995:

     Risk-free interest rates           5.74% - 6.01% 
     Expected life                        1.25 years 
     Volatility                              0.70 
     Dividend yield                           --- 
          
The weighted average fair value of those purchase rights granted in 1996 and 
1995 was $5.15 and $3.74, respectively.
          
The following proforma income information has been prepared following the 
provisions of SFAS No. 123:

The above proforma effects on income may not be representative of the effects 
on net income for future years as option grants typically vest over several 
years and additional options are generally granted each year.

The effective income tax rate in each year was impacted by a reduction in the 
Company's valuation allowance against deferred tax assets of $1.6 million, 
$6.8 million and $1.1 million for 1996, 1995 and 1994, respectively.

No provision has been made for federal, state or foreign taxes that may 
result from future remittances of undistributed earnings of foreign 
subsidiaries ($649,000 at December 31, 1996) because it is expected that such 
earnings will be reinvested in these foreign operations.  It is not practical 
to estimate the amount of taxes that might be payable on the eventual 
remittance of such earnings.  
               
The Company's income taxes currently payable for both federal and state 
purposes have been reduced by the tax benefit derived from the disqualifying 
dispositions of incentive stock options and the exercise of nonqualified 
stock options.  The benefit, which totalled $999,000 in 1996 and $545,000 in 
1995 was credited directly to additional paid-in capital.

At December 31, 1996, the Company had approximately $2,100,000 of combined 
net operating losses and federal and state tax credit carryforwards of 
$300,000 and $50,000, respectively. The carryforwards expire in 2005 through 
2010, if not utilized.  A significant portion of the Company's net operating 
loss and tax credit carryforwards is subject to an annual limitation of 
approximately $1,200,000.

13   EMPLOYEE BENEFIT PLANS   
               
The Company maintains 401(k) savings plans to provide retirement benefits 
through tax deferred salary deductions for all its employees.  The Company 
may make discretionary contributions as determined by the Board of Directors, 
which cannot exceed a percentage of the annual aggregate salaries of those 
employees eligible to participate. The Company has made total contributions 
to the plans of $394,000 for the year ended December 31, 1996, and none for 
the years ended December 31, 1995 and 1994.




14   CONTINGENCIES  
               
In January 1995, the Company and certain of its officers and directors were 
named in a securities class action filed in the United States District Court 
for the Northern District of California. The complaint seeks unspecified 
damages and related fees and costs. In September 1995, the Court dismissed 
with prejudice all claims against several defendants, including the Company's 
outside directors. The Court also dismissed with prejudice many of the 
allegations and claims asserted against the Company and certain of its 
officers.  While the Company believes that it has meritorious defenses to the 
claims remaining in the action, the Company has entered into a Stipulation of 
Settlement with plaintiffs in order to conserve legal expenses and management 
resources. The Company's contribution to the proposed $2.75 million 
settlement, net of insurance proceeds, is not material.  The proposed 
settlement has been preliminarily approved by the Court but remains subject 
to the Court's final approval. There can be no assurance that the Company 
will in fact succeed in obtaining final Court approval of the proposed 
settlement with the plaintiffs. In the event the Court does not grant final 
approval of the settlement, the Company will continue to contest this action 
vigorously.  While the outcome of the action in the absence of the proposed 
settlement cannot be predicted with certainty, management does not believe 
the outcome will have a material adverse impact on the Company's financial 
position or results of operations.

Additionally, in January 1996, the Company filed a complaint with the 
International Trade Commission (the "ITC") in Washington, DC, seeking to stop 
unfair importation of logic emulation systems manufactured by Meta Systems 
("Meta") of France, a subsidiary of Mentor Graphics Corporation ("Mentor").   
In the complaint, the Company alleges that Mentor's hardware logic emulation 
systems infringe the Company's patents. In July 1996, the ITC Administrative 
Law Judge issued an Initial Determination granting a Temporary Exclusion 
Order stopping the importation of Mentor Graphic's emulation products into 
the U.S., absent the posting of a bond by Mentor.  The ITC Initial 
Determination included a Cease and Desist Order against all sales activities 
of the Mentor emulation products into the U.S. In August 1996, the ITC 
ratified the judge's Initial Determination.  The Company is continuing its 
legal efforts with the ITC to obtain a Permanent Exclusion Order stopping the 
importation of Mentor's emulation products into the U.S.  The Company also is 
engaged in a Federal District Court case involving six of the Company's 
patents.  Mentor and Meta are seeking a declaratory judgment of 
noninfringement, invalidity and unenforceability of the patents in dispute, 
and the Company has filed counteractions against Mentor and Meta for 
infringement and threatened infringement of the six patents.  Mentor has also 
claimed in this Federal District Court case that press releases issued by the 
Company were defamatory and interfered with Mentor's business advantage. 
Additionally, Aptix Corporation recently filed a suit against the Company 
alleging various violations of the antitrust laws and unfair competition.  
The Company does not believe these claims are meritorious and plans to mount 
a vigorous defense against them.  The outcome of these actions cannot be 
predicted with certainty.  




The Company is engaged in certain other legal and administrative proceedings 
incidental to its normal business activities.  While it is not possible to 
determine the ultimate outcome of these actions at this time, management 
believes that any liabilities resulting from such proceedings or claims which 
are pending or known to be threatened, will not have a material adverse 
effect on the Company's consolidated financial position or results of 
operations.

15  SUBSEQUENT EVENT    

On February 7, 1997, the Company acquired SpeedSim, Inc. ("SpeedSim"), a 
provider of cycle-based simulation software for the verification of digital 
logic designs (the "SpeedSim Merger").  The Company purchased all of the 
outstanding capital stock and assumed all of the outstanding stock options of 
SpeedSim, a privately held company, for an aggregate of approximately 2.8 
million shares of Quickturn common stock.  The Company estimates that it will 
incur direct transaction costs of at least $1.2 million associated with the 
acquisition, which will be charged to operations during the quarter ending 
March 31, 1997. The acquisition was accounted for as a pooling of interests, 
and accordingly, historical financial data in future reports of the Company 
will be restated to include SpeedSim data.  The following unaudited pro forma 
data summarizes the combined results of operations of the Company and 
SpeedSim for the years presented except for 1994, which had an immaterial pro 
forma impact on results of operations and net income per share:

REPORT OF INDEPENDENT ACCOUNTANTS  
               
To the Board of Directors and Stockholders   
Quickturn Design Systems, Inc.     
Mountain View, California     
   
We have audited the accompanying consolidated balance sheets of Quickturn 
Design  Systems, Inc. as of December 31, 1996 and 1995, and the related 
consolidated statements of income, stockholders' equity and cash flows for 
each of the three years in the period ended December 31, 1996.  These 
financial statements are the responsibility  of the Company's management.  
Our responsibility is to express an opinion on these  financial statements 
based on our audits. 
               
We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above 
present fairly, in all material aspects, the consolidated financial position 
of Quickturn Design Systems, Inc. as of December 31, 1996 and 1995, and the 
consolidated results of its operations and its cash flows for each of the 
three years in the period ended December 31, 1996 in conformity with 
generally accepted accounting principles.
