           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.   Basis of Presentation

     The accompanying unaudited consolidated financial statements at April 1,
     2000 and for the three and six months ended April 1, 2000 and April 3,
     1999, have been prepared in conformity with generally accepted accounting
     principles, consistent with those applied in, and should be read in
     conjunction with, the audited consolidated financial statements for the
     year ended October 2, 1999 included in the Form 10-K as filed with the
     Securities and Exchange Commission on December 20, 1999.  The unaudited
     interim financial information reflects all normal recurring adjustments
     which are, in the opinion of management, necessary for a fair statement of
     results for the interim periods presented.  The results for the three  and
     six month periods ended April 1, 2000 are not necessarily indicative of
     results expected for the full year.

     Certain reclassifications, none of which affected net income, have been
     made to prior year's amounts to conform to the current year's presentation.

3.   Net Income Per Share

     The computation of basic net income per share for the periods presented is
     derived from the information on the face of the income statement, and there
     are no reconciling items in either the numerator or denominator.
     Additionally, there are no reconciling items in the numerator used to
     compute dilutive net income per share.  The incremental common shares
     attributable to outstanding options for the three and six months ended
     April 1, 2000 and April 3, 1999 included in the total shares used in the
     denominator of the diluted net income per share calculation are as follows
     (in thousands):

5.   Recent Accounting Pronouncements

     In December 1999, the Securities and Exchange Commission (SEC) issued Staff
     Accounting Bulletin 101, (SAB 101), "Revenue Recognition in Financial
     Statements". SAB 101 summarizes the SEC's views in applying generally
     accepted accounting principles to selected revenue recognition issues. We
     are required to apply the guidance in SAB 101 to our financial statements
     no later than the first quarter of fiscal 2001. Changes in the Company's
     revenue recognition policy resulting from the interpretation of SAB 101
     would be reported as a change in accounting principle in the quarter ending
     December 30, 2000. The change in the revenue recognition policy would
     result in a cumulative adjustment in the first quarter of 2000 to reflect
     the deferral of revenue for shipments previously reported as revenue, that
     do not meet SAB 101 revenue recognition. The Company is currently
     evaluating the impact of the new SAB.

6.   Subsequent Events

     Subsequent to April 1, 2000, the Company completed the establishment of a
     line of credit with its bank.  Under the terms of the agreement, the
     Company will be able to utilize up to $3,000,000 for working capital
     purposes and an additional $1,500,000 for capital acquisitions.

ITEM 2. Management's Discussion and Analysis of Financial Condition
        and Results of Operations

Cautionary Statement

The statements in the Management's Discussion and Analysis of Financial
Condition and Results of Operations that are forward looking involve numerous
risks and uncertainties and are based on current expectations.  Actual results
may differ materially from those projected.  Such risks and uncertainties may be
more fully described in other reports and information filed by the Company with
the Securities and Exchange Commission. Certain of these risks and uncertainties
are discussed under the caption "Factors That May Affect Future Results of
Operations."

Net Revenues

Net revenues for the three and six month periods ending April 1, 2000 were
$16,799,000 and $32,204,000, respectively, representing a 23% and 29% increase
over the same periods of the prior year.  The increase was a result of increases
in both product and maintenance revenues.  For the three months ended April 1,
2000, product revenues increased as result of increases in both emulation and
simulation sales during the quarter.  Emulation revenues increased approximately
17% over the prior year's quarter as the product continues to be accepted in the
marketplace.  However, these results were slightly lower than the previous
quarter. The decline from quarter to quarter is believed to be a timing issue
and the Company expects continued growth of emulation revenues over the next two
quarters.  For the six month period, emulation revenues grew by over 50% when
compared to the prior year six month period.  The increase is a result of the
increased acceptance of the Company's current emulation offerings and the
ongoing upgrades to the product itself. Simulation revenues were 32% higher than
the prior year's quarter and 27% higher than the previous quarter.  For the six
month period, simulation revenues increased 27% when compared to the same period
in fiscal 1999.  The increase is directly related to the Company's newer
simulation products which continue to sell at a higher than expected level.  The
Company anticipates that the ongoing revenue growth will be mainly from its
emulation products and the simulation revenues will show flat to lower results
as the transition to emulation continues.

For the three and six month period ended April 1, 2000, maintenance revenues
have increased due to the Company's current Voyager system installed base and
the Company's increasing emulation system installed base which has resulted in
an overall higher installed base of systems which are under maintenance
agreements. Maintenance revenues are expected to continue to grow, as they
relate to the emulation products.  However, the overall growth of maintenance
revenues may be limited due to fewer customers renewing their maintenance for
the simulation products as this business evolves.

International sales for the quarter totaled $4,513,000 or approximately 27% of
total revenues.  International revenues for the quarter were slightly lower when
compared to the prior year quarter.  The decrease in revenues is primarily due
to timing of orders and shipments.  For the six month period, international
revenues totaled $11,923,000 or 37% of total revenues and represents an increase
of 29% from the same period a year ago.  The increases are due to higher sales
in the first quarter as a result of the timing of orders and shipments.

Gross Profit Margins

Gross profit margins for the three and six month periods ended April 1, 2000
were 78% and 77%, respectively.  Gross profit margins for the three and six
month periods ended April 3, 1999 were 75%.  The increase in the product margins
is due to sales of higher margin products and the increased manufacturing
efficiencies.  Product margins increased due to the volume while maintenance
margins decreased as a result of higher support costs related to newer products.

Research and Development Expenses

Research and development expenses for the three and six month periods ending
April 1, 2000 were approximately $3,953,000 and $7,207,000, respectively or 24%
and 22% of net revenues. This represented an increase of 15% over the second
quarter of 1999 and 12% for the six month period.  Research and development
expenses increased primarily as a result of increased salaries, consulting costs
and prototype costs.  The Company expects that research and development expenses
will continue to increase as the Company continues to upgrade its current
offerings and research new possibilities.

Sales and Marketing Expenses

Sales and marketing expenses for the three and six month periods ending April 1,
2000 were approximately $5,760,000 and $11,681,000, respectively or 34% and 36%
of net revenues. This represented an increase of 4% and 15% over the same three
and six month periods in fiscal 1999.  The increase over the prior year quarter
and six month period is primarily related to increase salaries, commissions and
consulting expenses.

General and Administrative Expenses

General and administrative costs for the three and six month periods ending
April 1, 2000 were $1,288,000 and $2,341,000 or 8% and 7% of net revenues.  For
the three and the six month periods, the general and administrative expenses
were comparable with the prior year in terms of percentage of revenues although
slightly higher in absolute dollars as a result of increased salaries and
related expenses. General and administrative costs are expected to remain flat
as a percentage of revenues over the remainder of fiscal 2000.

Income Taxes

The Company's effective tax rate on the consolidated pretax income for the three
and six month periods ended April 1, 2000 is 25%, as compared to an effective
tax rate of 18% and 15% for the three and six month periods of fiscal 1999. The
Company's 2000 effective tax rate for the three and six month periods ended
April 1, 2000 differs from the federal statutory rate primarily due to benefits
associated with its net operating loss carryforward.  The Company's 1999
effective tax rate for the three and six month periods ended April 3, 1999
differs from the federal statutory rate primarily due to benefits associated
with its net operating loss carryforward.

Other

The Company has experienced minimal gains or losses on foreign currency
translation since substantially all of its international sales to date have been
billed and collected in U.S. dollars. The Company pays the expenses of its
international operations in local currencies and to date the Company has not
engaged in hedging transactions with respect to such obligations.  The Company
has reorganized its operations at its Japan subsidiary and is engaging in
transactions in the Japanese local currency.  As such, the Company periodically
enters into foreign exchange contracts to minimize foreign exchange risk
relating to the Japanese subsidiary's sales that are denominated in yen.  A
forward exchange contract obligates the Company to exchange predetermined
amounts of a specified foreign currency at a specified exchange rate on a
specified date or to make an equivalent US dollar payment equal to the value of
such exchange.  These contracts are accounted for as hedges of identifiable
receivables denominated in Japanese yen.  Realized gains or losses are
recognized  upon  maturity of  the contracts and offset the underlying asset or
liability. Through April 1, 2000, the impact of such hedging arrangements have
been immaterial to the Company operations.

Factors that May Affect Future Results of Operations

Potential Fluctuations in Quarterly Results - The Company's quarterly operating
-------------------------------------------
results have in the past and may in the future vary significantly depending on
factors including the timing of customer development projects and purchase
orders, new product announcements and releases by the Company and other
companies, gain or loss of significant customers, price discounting of the
Company's products, the timing of expenditures, customer product delivery
requirements, availability and cost of components or labor and economic
conditions generally and in the electronics industry specifically. Any
unfavorable change in these or other factors could have a material adverse
effect on the Company's operating results for a particular quarter. Many of the
Company's customers order on an as-needed basis and often delay issuance of firm
purchase orders until their project commencement dates are determined. Quarterly
revenue and operating results will therefore depend on the volume and timing of
orders received during the quarter, which are difficult to forecast accurately.
Moreover, a significant portion of the Company's revenue may result from
shipments during the last few weeks of the quarter from orders generally
received in the last month of the quarter. Any concentration of sales at the end
of the quarter may limit the Company's ability to plan or adjust operating
expenses and production and inventory levels. Therefore, if anticipated
shipments in any quarter do not occur or are delayed, expenditure levels could
be disproportionately high as a percentage of revenue, and the Company's
operating results for that quarter would be adversely affected. In addition,
sales of individual systems with high average sales prices can constitute a
significant percentage of the Company's quarterly revenue. Operating results in
any period should not be considered indicative of the results to be expected for
any future period, and there can be no assurance that the Company's net revenues
will increase or that the Company will remain profitable in any future period.

Sales Trends - Over the past several years the marketplace for the Company's
------------
products has evolved substantially. The Company has seen a significant reduction
in sales of its simulation products as revenues have declined from approximately
$37,044,000 in fiscal 1997 to approximately $19,463,000 in fiscal 1999.
Simulation revenues were approximately $10,894,000 for the first six months of
fiscal 2000. While the overall decrease is due in part to the evolution of the
market, the primary cause of the decrease is the result of the Company's focus
on its new emerging product line of emulation solutions. The Company has seen
its revenues from its emulation products increase from approximately $6,000,000
in fiscal 1997 to over $20,000,000 in

                                       10
<PAGE>

fiscal 1999. The Company anticipates that the simulation product revenue will
continue to decrease, however, on a slower pace over the next year and its
emulation revenues will increase resulting in increased sales overall. There
can be no assurance that the Company will be able to maintain these expected
trends. These trends will be dependent upon the Company introducing new
products and methodologies. Furthermore, increased overall sales will also
depend on an increasing number of complex ICs designed for electronic systems,
integration of the Company's products with other tools for IC design, the
ability of the Company's products to shorten overall customer design cycles
and increased industry acceptance of the Company's verifications solutions.
Because the market for hardware-assisted verification products is evolving, it
is difficult to predict with any assurance whether the markets for such
solutions will continue to expand. There can be no assurances that such market
will expand, or even if such market expands, that the Company's products will
achieve and maintain the market acceptance required to maintain revenue growth
and profitability in the future.

New Product Development - To continue its expected revenue growth, the Company
-----------------------
needs to continue to invest in new product development. The Company continues to
focus most of its development resources on its emulation products. Since fiscal
1997, when the Company released its first generation emulator, the Company has
released two new generations of its emulation product. The Company has seen
favorable results with its latest release; however, there can be no assurance
that the product will continue to meet the requirements of the marketplace.
There continues to be further development of the emulation product as well as
other verification products, and as the Company continues to develop such
products, which are based on the new technology, there can be no assurance that
the enhanced products or other developed products resulting from this
development will provide the necessary solutions for customer design
verification needs, be of acceptable quality or achieve further market
acceptance. The success of the Company in developing, introducing, selling and
supporting verification products will depend on a variety of factors, including
but not limited to, the timely and successful enhancement of current products,
completion of product design and development of future products, the timely and
efficient implementation of manufacturing processes, effective sales, marketing
and customer service. However, performance problems or other difficulties that
may require design modifications and related expenses may hinder or damage
market acceptance of the products. While the Company's verification systems are
designed to provide cost and ease of use advantages intended to broaden the
market for hardware-assisted verification, there can be no assurance that its
products will be able to achieve such goals. Moreover, there can be no assurance
that the market for such verification solutions will broaden beyond the current
set of users.

Competition - The EDA industry is highly competitive and rapidly changing. The
-----------
Company's products are specifically targeted at the emerging portion of the
industry relating to complex designs that the Company believes benefit from its
verification products. The Company currently competes with traditional software
verification methodologies, including product offerings sold by Cadence,
Synopsis and Mentor Graphics. The Company's main competition for the sale of
emulation systems is Quickturn/Cadence. The Company expects competition in the
market for verification tools to increase as other companies attempt to
introduce new products and product enhancements. Moreover, the Company competes,
and expects that it will continue to compete, with established EDA companies. A
number of these companies have longer operating histories, significantly greater
financial, technical and marketing resources, greater name recognition and
larger installed customer bases than the Company. In addition, many of these
competitors and potential competitors have established relationships with
current and potential customers of the Company and offer a broader and more
comprehensive product line. Increased competition could

                                       11
<PAGE>

result in price reductions, reduced margins and loss of market share, all of
which could materially adversely affect the Company. In addition, current
competitors or other entities may develop other products that have significant
advantages over the Company's products. 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 operating results.

New Products and Technological Change - The EDA industry is characterized by
-------------------------------------
extremely rapid technological change in both hardware and software development,
frequent new product introductions, evolving industry standards and changing
customer requirements. The introduction of products embodying new technologies
and the emergence of new industry standards can render existing products
obsolete and unmarketable. The Company's future success will depend upon its
ability to enhance its current series of simulation and emulation systems and to
design, develop and support its future simulation and emulation products on a
timely basis. These efforts require a high level of expenditures for research
and development by the Company to address the increasingly sophisticated needs
of the customers. For example, all of the Company's current products operate in,
and planned future products will operate in, the Unix operating environment, an
industry standard in the EDA market. In the event that another operating system,
such as Windows NT, becomes an industry standard, the Company may be required to
port its products to such new standard. In addition, the Company's simulation
systems generally accept designs in the broadly accepted hardware description
language, Verilog-XL, which Cadence has developed and made available to the
Company. In the event Cadence adopts a less cooperative stance toward the
Company in the future, the Company's systems may not be able to accept designs
based on Verilog-XL and the Company may be required to develop software to
accept designs of other hardware description languages. The inability to accept
designs in Verilog-XL may materially adversely affect the Company's results of
operations. There can be no assurance that the Company will be successful in
developing and marketing product enhancements or new products that respond to
technological change or evolving industry standards or changing customer
requirements, that the Company will not experience difficulties that could delay
or prevent the successful development, introduction and marketing of these
products, or that its new products and product enhancements will adequately meet
the requirements of the marketplace, will be of acceptable quality or will
achieve market acceptance. If the Company is unable, for technological or other
reasons, to develop and introduce products in a timely manner in response to
changing market conditions or customer requirements, the Company's business,
operating results and financial condition will be materially and adversely
affected. Moreover, from time to time, the Company may announce new products
or technologies that have the potential to replace the Company's existing
product offerings. There can be no assurance that the announcement of new
product offerings will not cause customers to defer purchases of existing
Company products, which could adversely affect the Company's results of
operations for any particular quarter.

Dependence on Electronics Industry - The Company is dependent upon the
----------------------------------
electronics industry and, in particular, new system and IC design projects. The
electronics industry is characterized by rapid technological change, short
product life cycles, fluctuations in manufacturing capacity and pricing and
margin pressures, all of which cause it to be volatile. As a result, the
electronics industry has historically experienced sudden and unexpected
downturns, at which time the number of new system and IC design projects
decrease. Because most of the Company's sales occur upon the commencement of new
projects for system and IC products, the Company is dependent upon the rate of
commencement of new system and IC design projects. Accordingly, negative factors
affecting the electronics industry could have a material adverse effect on the
Company's results of operations.

                                       12
<PAGE>

Dependence Upon Certain Suppliers - Certain key components used in the Company's
---------------------------------
products are presently available from sole or limited sources. The inability to
develop alternative sources for these sole or limited source components or to
obtain sufficient quantities of these components could result in delays or
reductions in product shipments which could adversely affect the Company's
operating results. The Company's systems use proprietary ASICs and FPGAs that
are currently manufactured solely by American Microsystems, Inc. ("AMI") and
Xilinx, Inc. ("Xilinx"), respectively.

The Company generally purchases these components, including semiconductor
memories used in the Company's verification hardware, pursuant to purchase
orders placed from time to time in the ordinary course of business and has no
supply arrangements with any of its source suppliers that require the suppliers
to provide components in guaranteed quantities or at set prices. Moreover, the
manufacture of these components can be extremely complex, and the Company's
reliance on the suppliers of these components exposes the Company to production
difficulties and quality variations that may be experienced by these suppliers.
Therefore, the Company's reliance on its sole and limited source suppliers
involves several risks, including a potential inability to obtain an adequate
supply of required components, reduced control over pricing and timely delivery
and quality of acceptable components. While the timeliness and quality of
deliveries to date from such suppliers have been acceptable, there can be no
assurance that problems will not occur in the future. Any prolonged inability to
obtain components or subassemblies in sufficient quantities or quality or on
favorable pricing or delivery terms, or any other circumstances that would
require the Company to seek alternative sources of supply, could have a material
adverse effect on the Company's operating results and could damage the Company's
relationships with its customers.

Customer Concentration - A relatively limited number of customers have
----------------------
historically accounted for a substantial portion of the Company's net revenues.
During fiscal 1999, 1998 and 1997, sales to the Company's top ten customers
accounted for approximately 60%, 45% and 52%, respectively, of the Company's net
revenues. The Company expects that sales of its products to a limited number of
customers will continue to account for a high percentage of net revenues for the
foreseeable future. The loss of a major customer or any reduction in orders by
such customers, including reductions due to market or competitive conditions in
the electronics or EDA industries, would have an adverse effect on the Company's
results of operations. Moreover, the Company's ability to increase its sales
will depend in part upon its ability to obtain orders from new customers, as
well as the financial condition and success of its existing customers and the
general economy. There can be no assurance that such increases will occur.

Sales Support Personnel - Due the complex and technical environment, in which
-----------------------
the Company operates, the Company's products require a significant level of pre-
sale support and in certain instance post-sale support. Due to the current
competitive environment for these support resources, the Company is faced with
many challenges in hiring, training and retaining the best application support
resources available. While the Company has been successful in the past in hiring
and training sales support personnel, there are no guarantees that the Company
can continue to hire and retain new employees as needed. Should the Company be
unable to attract and maintain an adequate level of application support
personnel, the Company's sales and support operations could be adversely
impacted. It is the Company's position to be competitive in the hiring,
training and retention of such personnel.

Liquidity and Capital Resources

Since inception, the Company has financed its operations, including increases in
accounts receivable, inventory and capital equipment acquisitions, primarily
through private and public sales of equity securities and a loan secured by
capital equipment. The Company's cash, cash equivalents and short-term
investments increased to $15,348,000 at April 1, 2000 from $10,534,000 at
October 2, 1999.  The increase was a result of $5,411,000 of cash provided by
operating activities, $1,490,000 of cash used in investing activities (excluding
short-term investment activities) and $893,000 of cash provided by financing
activities.

Operating Activities - The Company's operating activities provided cash of
--------------------
$5,411,000 during the first six months of fiscal 2000.  The $5,411,000 of cash
provided by operations was primarily due to net income adjusted for
depreciation, amortization, accumulated translation adjustments and deferred
rent, decreases in prepaid expenses and other assets, combined with increases in
accounts payable, deferred revenues, taxes payable and accrued commissions.
These increases in cash were offset by increases in accounts receivable and
inventories combined with decreases in accrued payroll and related expenses and
other accrued expenses.

Investing Activities - Net cash used in investing activities for the first six
--------------------
months of 2000 was $2,136,000.  The $2,136,000 of cash used was primarily the
result of $2,323,000 obtained from maturities of short-term investment offset by
purchases of short-term investments of $2,969,000 and acquisition of capital
equipment of $1,490,000.

Financing Activities - Net cash provided by financing activities for the six
--------------------
months ended April 1, 2000, was $893,000 and was primarily related to the net
sales of stock under stock option and purchase plans during the six months.

The Company's primary unused sources of funds at April 1, 2000 consisted of
$11,832,000 of cash and cash equivalents, in addition to $3,516,000 of short-
term investments. In April 2000, the Company completed the signing of a new
credit facility that provides a $3,000,000 working capital line and a $1,500,000
capital equipment line.  The Company believes that its current cash, cash
equivalents, short-term investments and its current credit facility, together
with cash and cash equivalents generated from operations will be sufficient to
finance its operations for at least the next twelve months. Should the Company
require other financing arrangements, there can be no assurance that such
financing will be available, if at all, on terms favorable or acceptable to the
Company.
