                       							   PART I

Item 1.  Business


                       							  General

Mentor Graphics Corporation (Mentor Graphics or Company), an Oregon
corporation organized in 1981, is headquartered in Wilsonville, Oregon.
The Company's common stock is traded in the NASDAQ National Market System
under the symbol MENT.

			    
                					    Products and Services

The Company designs, manufactures, markets and supports electronic design
automation (EDA) software for the integrated circuit (IC) and systems design
markets.  The Company provides a broad range of EDA tools developed either by
the Company or together with third parties to support the entire electronic
design process.  The Company's software products enable engineers and
designers to design, analyze, place and route, and test custom (ASICs),
printed circuit boards, multichip modules and other electronic systems and
subsystems. The Company's Falcon Framework software provides a common
foundation for the Company's EDA software products. Falcon Framework
software also allows for the integration of third party software tools
developed by other commercial EDA vendors and by customers for their own 
internal use.  The Company's products help customers reduce development
time while producing innovative hardware products of high quality.  In
addition to software products, Mentor Graphics'Professional Services
Division offers consulting, support and training services to enhance
customers' success in the design and manufacture of hardware products.


                      							  Platforms

The Company's software runs on UNIX workstations in a broad range of price
and performance levels, including workstations manufactured by
Hewlett-Packard Company, Sun Microsystems, Inc.,  Digital Equipment
Corporation,  NEC Corporation and International Business Machine
Corporation (IBM).  The above major computer manufacturers have a
substantial installed base of workstations, and make frequent introductions
of new products with significant price/performance improvements.

The Company has written virtually all of its software in the high level
languages C++, C, Pascal, or Fortran to facilitate its portability to other
platforms in the future, should availability of the Company's software on
such platforms prove desirable. 


              					      Marketing and Sales

The Company's marketing strategy emphasizes customer support, professional
consulting services, a strong direct sales force and large corporate account
penetration in the semiconductor, aerospace, computer, telecommunications,
automotive and consumer electronics industries. Customers use the Company's
products in the design of such diverse products as supercomputers,
automotive electronics, missile guidance systems, signal processors,
personal computers, gallium arsenide circuits, microprocessors and
telecommunication switching systems.

Mentor Graphics sells and licenses its products primarily through its direct
sales force in the United States, through the direct sales forces of its
wholly-owned subsidiaries in Asia and Europe and through distributors. 
During the years ending December 31, 1994 and 1993, sales outside of
North America accounted for 45 and 46 percent, respectively, of total sales.
Additional information relating to foreign and domestic operations is
contained in Note 14 of Notes to Consolidated Financial Statements on pages
37-38 of the 1994 Annual Report to Shareholders and is incorporated by this
reference.  Fluctuating exchange rates and other factors beyond the
Company's control, such as tariff and trade policies, domestic and foreign
tax and economic policies and the relative stability of international
economic and monetary conditions should continue to affect the level
and profitability of sales outside the United States.

The Company's OpenDoor program coordinates and supports the integration
of third party EDA products, both commercial and internally developed
by customers, into the Falcon Framework environment.  Under this program,
the Company enables OpenDoor participant companies to develop interfaces
from their products to the Company's products.  OpenDoor participants can
select from a range of integration technologies to achieve an optimal
degree of integration for their products.  There are now approximately 130
OpenDoor participants.

No material portion of the Company's business is dependent on a single
customer.  The Company has traditionally experienced some seasonal
fluctuations in receipt of orders, which are typically stronger in the
second and fourth quarters of the year.  As is typical of many other
companies in the the electronics industry, the Company generally ships
its products to customers within 10 to 90 days after receipt of an order,
and a substantial portion of quarterly shipments tend to be made in
the last month of each quarter.

The Company sells and licenses its products and some third-party products
pursuant to purchase orders and master purchase and license agreements.
The Company has corporate agreements providing the general terms and
conditions of sales and discounts to certain of its customers.
Company schedules deliveries only after receipt of purchase orders under
these agreements.


                  					  Manufacturing Operations

The Company's manufacturing operations primarily consist of reproduction
of the Company's software and documentation.  In North America,
manufacturing occurs at the Company's facility in Wilsonville, Oregon.
Software and documentation distribution centers in The Netherlands
Japan and Singapore serve their respective regions.  The Company uses a
manufacturing resource planning system which integrates purchasing,
inventory control and accounting in all regions.


                 					     Product Development

The EDA market is competitive and characterized by rapid technological
change, which requires continuous high expenditures for the enhancement
of existing products and the development of new products.  The Company is
committed to the creation of new products and intends to continue to
enhance its existing products.  During the years ended December
1992, the Company expensed approximately $72,484,000, $77,598,000
and $73,947,000 respectively, and capitalized approximately $5,156,000,
$3,609,000 and $6,120,000, respectively, related to product development.
Substantially all of these costs were related to the development
of the Company's proprietary application software.


                      							   Suppliers

The Company contracts with several suppliers who provide software products
which the Company integrates into its product line, allowing the Company
to both concentrate its development efforts on its core product line
and offer its customers a more complete design solution.


               		 Customer Support and Professional Services

The Company has a worldwide organization to meet its customers' needs
for software support, training, consulting, custom IC design and
documentation.  The Company offers support contracts providing software
updates and support.  Most of the Company's customers are covered
by software support contracts.  The Company provides technical support for
its products through a direct telephone support line and an electronic
communications system.

An important component of the total solution provided to customers is
professional services offered through the Company's Professional Services
Division which provides consulting and training to help the Company's
customers improve their design processes and make the most efficient use of
their EDA software tools.  Professional Services consultants specialize in
providing software and services for design data management and electronic
parts data creation, co-design of ASICs, ICs, printed circuit boards
and multichip modules and EDA network and design environment management
and software integration.


                        				Competition

The EDA industry is competitive and has been characterized by rapid
technological advances in application software, operating systems and
hardware.  The Company's principal competitors are Cadence Design Systems
Inc., Synopsys Inc., Viewlogic Systems, Inc., COMPASS Design Automation,
Inc., Zuken Incorporated and Intergraph Corporation.  The Company believes
that other companies may be developing EDA systems.

Some of the Company's competitors and potential competitors may have
greater financial and marketing resources than Mentor Graphics.  However,
the Company believes the main competitive factors in the EDA industry are
breadth and quality of application software, product integration, ability
to respond to technological change, quality of a company's
size of the installed base, level of customer support and value added
services.  The Company believes that it generally competes favorably in
these areas.  The Company can give no assurance, however, that it will have
the financial resources, marketing, distribution and service capability
depth of key personnel or technological knowledge to compete successfully
in the EDA market.


                           				  Employees

The Company and its subsidiaries employed approximately 2,050 persons full
time as of December 31, 1994 compared with approximately 2,100 persons at
the end of 1993.  The Company's success will depend in part on its ability
to attract and retain employees who are in great demand.  The Company
continues to enjoy good employee relations.  No Company employees are
represented by a collective bargaining unit.


                   			      Patents and Licenses

The Company owns United States and Canadian patents covering the technology
underlying several of its software products.  The Company has also filed
other patent applications on technology it has developed and intends to file
additional patent applications in the future.  While the Company believes
the pending applications relate to patentable devices, the
assurance that any patent will be issued or that any patent can be
successfully defended.  The Company believes that patents are less
significant to the success of its business than technical competence,
management ability, marketing capability and customer support.

The Company regards its application software as proprietary and attempts
to protect it with copyrights, trade secret laws, and internal
non-disclosure safeguards, as well as patents, when appropriate, as noted
above.  The Company typically incorporates restrictions on
usage and transferability into its agreements with customers and other
third parties.


Item 2.  Properties

The Company's Wilsonville, Oregon facilities are located in six owned
buildings of approximately 420,000 total square feet located on about 90
acres.  All corporate functions, as well as a majority of research and
development and domestic activities, operate from this site.

The Company leases additional space in San Jose, California, and in various
locations throughout the United States and in foreign countries, primarily
for sales and customer service operations. The Company believes that it will
be able to renew or replace its existing leases as they
that its current facilities will be adequate through at least 1995.


Item 3.  Legal Proceedings

There are no material legal proceedings pending against the Company.


Item 4.  Submission of Matters to a Vote of Security Holders

No matters were submitted to a vote of the security holders of the Company
during the fourth quarter of the fiscal year ended December 31, 1994.

(1)     Deductions primarily represent accounts written off during the period.

(2)     Deductions represent inventory scrapped during each period and
	reclassification of demonstration equipment from inventory to
	property plan and equipment in 1994.  

(3)     Deductions primarily represent payments made to carry out
	restructure plans and reversals of accrued restructure charges due
	to changes in estimates of $10,045, $1,400 and $1,600 
	for the years ended December 31, 1994, 1993 and 1992, respectively.  

(4)     Addition represents adoption of Statement of Financial Accounting
	Standards No. 109, "Accounting for Income Taxes" on January 1, 1993
	and increases to the valuation allowance during the year.  As such,
	the Company established a valuation allowance for certain deferred
	tax assets, including net operating loss and tax credit carryforwards.
	statements No. 109 requires that such a valuation allowance be
	recorded when it is more likely than not that some portion of the
	deferred tax assets will not be realized.  The deduction in 1994
	primarily represents the realization of net operating loss
	carryforwards for the year.
