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.

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.

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



<PAGE>


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.

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.



<PAGE>

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

<PAGE>

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



<PAGE>

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



<PAGE>

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

<PAGE>


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.



<PAGE>

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

<PAGE>

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.



<PAGE>

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.



<PAGE>

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.

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.

<PAGE>

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:

Net income per share - proforma              $    0.72     $    0.84

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.

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

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:
