Item 5.   Other Events.

          On February 9, 1996, the Board of Directors of Cadence Design
Systems, Inc. (the "Company") declared a dividend of one preferred share
purchase right (a "Right") for each outstanding share of common stock, par
value $.01 per share, of the Company (the "Common Stock").  The dividend is
payable on February 20, 1996 (the "Record Date") to the stockholders of record
on that date.  Each Right entitles the registered holder to purchase from the
Company one one-thousandth of a share of Series A Junior Participating
Preferred Stock, par value $.01 per share (the "Preferred Stock") of the
Company at a price of $240 per one one-thousandth of a share of Preferred Stock
(the "Purchase Price"), subject to adjustment.  The description and terms of
the Rights are set forth in a Rights Agreement dated as of February 9, 1996, as
the same may be amended from time to time (the "Rights Agreement"), between the
Company and Harris Trust and Savings Bank, as Rights Agent (the "Rights
Agent").  The rights issued under the old amended and restated rights
agreement, dated as of June 20, 1989, between the Company and the Rights Agent
expired at the close of business on February 9, 1996.

          Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") have acquired beneficial ownership of 15% or more of the
outstanding shares of Common Stock or (ii) 10 business days (or such later date
as may be determined by action of the Board of Directors prior to such time as
any person or group of affiliated persons becomes an Acquiring Person)
following the commencement of, or announcement of an intention to make, a
tender offer or exchange offer the consummation of which would result in the
beneficial ownership by a person or group of 15% or more of the outstanding
shares of Common Stock (the earlier of such dates being called the
"Distribution Date"), the Rights will be evidenced, with respect to any of the
Common Stock certificates outstanding as of the Record Date, by such Common
Stock certificate together with a copy of this Summary of Rights.

          The Rights Agreement provides that, until the Distribution Date (or
earlier redemption or expiration of the Rights), the Rights will be transferred
with and only with the Common Stock.  Until the Distribution Date (or earlier
redemption or expiration of the Rights), new Common Stock certificates issued
after the Record Date upon transfer or new issuances of Common Stock will
contain a notation incorporating the Rights Agreement by reference.  Until the
Distribution Date (or earlier redemption or expiration of the Rights), the
surrender for transfer of any certificates for shares of Common Stock
outstanding as of the Record Date, even without such notation or a copy of this
Summary of Rights, will also constitute the transfer of the Rights associated
with the shares of Common Stock represented by such certificate.  As soon as
practicable following the Distribution Date, separate certificates evidencing
the Rights ("Right Certificates") will be mailed to holders of record of the
Common Stock as of the close of business on the Distribution Date and such
separate Right Certificates alone will evidence the Rights.

          The Rights are not exercisable until the Distribution Date.  The
Rights will expire on February 9, 2006 (the "Final Expiration Date"), unless
the Final Expiration Date is extended or unless the Rights are earlier redeemed
or exchanged by the Company, in each case as described below.

          The Purchase Price payable, and the number of shares of Preferred
Stock or other securities or property issuable, upon exercise of the Rights are

subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Stock, (ii) upon the grant to holders of the Preferred Stock of
certain rights or warrants to subscribe for or purchase Preferred Stock at a
price, or securities convertible into Preferred Stock with a conversion price,
less than the then-current market price of the Preferred Stock or (iii) upon
the distribution to holders of the Preferred Stock of evidences of indebtedness
or assets (excluding regular periodic cash dividends or dividends payable in
Preferred Stock) or of subscription rights or warrants (other than those
referred to above).

          The number of outstanding Rights are also subject to adjustment in
the event of a stock split of the Common Stock or a stock dividend on the
Common Stock payable in shares of Common Stock or subdivisions, consolidations
or combinations of the Common Stock occurring, in any such case, prior to the
Distribution Date.

          Shares of Preferred Stock purchasable upon exercise of the Rights
will not be redeemable.  Each share of Preferred Stock will be entitled, when,
as and if declared, to a minimum preferential quarterly dividend payment of $1
per share but will be entitled to an aggregate dividend of 1000 times the
dividend declared per share of Common Stock.  In the event of liquidation, the
holders of the Preferred Stock will be entitled to a minimum preferential
liquidation payment of $1000 per share (plus any accrued but unpaid dividends)
but will be entitled to an aggregate payment of 1000 times the payment made per
share of Common Stock.  Each share of Preferred Stock will have 1000 votes,
voting together with the Common Stock.  Finally, in the event of any merger,
consolidation or other transaction in which shares of Common Stock are
converted or exchanged, each share of Preferred Stock will be entitled to
receive 1000 times the amount received per share of Common Stock.  These rights
are protected by customary antidilution provisions.

          Because of the nature of the Preferred Stock's dividend, liquidation
and voting rights, the value of the one one-thousandth interest in a share of
Preferred Stock purchasable upon exercise of each Right should approximate the
value of one share of Common Stock.

          In the event that any person or group of affiliated or associated
persons becomes an Acquiring Person, each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereupon become void),
will thereafter have the right to receive upon exercise of a Right at the then
current exercise price of the Right, that number of shares of Common Stock
having a market value of two times the exercise price of the Right.

          In the event that, after a person or group has become an Acquiring
Person, the Company is acquired in a merger or other business combination
transaction or 50% or more of its consolidated assets or earning power are
sold, proper provision will be made so that each holder of a Right (other than
Rights beneficially owned by an Acquiring Person which will have become void)
will thereafter have the right to receive, upon the exercise thereof at the
then current exercise price of the Right, that number of shares of common stock
of the person with whom the Company has engaged in the foregoing transaction
(or its parent), which number of shares at the time of such transaction will
have a market value of two times the exercise price of the Right.  

          At any time after any person or group becomes an Acquiring Person and
prior to the acquisition by such person or group of 50% or more of the

outstanding shares of Common Stock or the occurrence of an event described in
the prior paragraph, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such person or group which will have become
void), in whole or in part, at an exchange ratio of one share of Common Stock,
or one one-thousandth of a share of Preferred Stock (or of a share of a class
or series of the Company's preferred stock having equivalent rights,
preferences and privileges), per Right (subject to adjustment).

          With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price.  No fractional shares of Preferred Stock will be issued
(other than fractions which are integral multiples of one one-thousandth of a
share of Preferred Stock, which may, at the election of the Company, be
evidenced by depositary receipts) and in lieu thereof, an adjustment in cash
will be made based on the market price of the Preferred Stock on the last
trading day prior to the date of exercise.

          At any time prior to the time an Acquiring Person becomes such, the
Board of Directors of the Company may redeem the Rights in whole, but not in
part, at a price of $.01 per Right (the "Redemption Price").  The redemption of
the Rights may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may establish. 
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

          For so long as the Rights are then redeemable, the Company may,
except with respect to the redemption price, amend the Rights in any manner. 
After the Rights are no longer redeemable, the Company may, except with respect
to the redemption price, amend the Rights in any manner that does not adversely
affect the interests of holders of the Rights. 

          Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the
right to vote or to receive dividends.

          This summary description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights Agreement,
as the same may be amended from time to time, which is hereby incorporated
herein by reference.

          The Rights have been issued in place of the Company's previous common
share purchase rights issued in 1989.  The principal differences between the
old rights and the new Rights are (1) the new Rights are exercisable for shares
of Preferred Stock instead of Common Stock, (2) an increase in the exercise
price from $66.67 (as adjusted to reflect the Company's stock split) to $240
per share; (3) the reduction in the threshold percentage from 20% to 15%; and
(4) the elimination of a provision in the old rights plan permitting redemption
of the rights during the 10 days after a person or group becomes an Acquiring
Person.
