Exhibit 10.35
                                 INNOVEDA, INC.

                   EXECUTIVE INCENTIVE STOCK OPTION AGREEMENT
                       GRANTED UNDER AMENDED AND RESTATED
                            2000 STOCK INCENTIVE PLAN

1.       GRANT OF OPTION.

         This agreement evidences the grant by Innoveda, Inc., a Delaware
corporation (the "Company"), on the effective date set forth in the attached
Notice of Grant of Stock Option and Option Agreement (the "Grant Date") to the
person named in the attached Notice of Grant of Stock Option and Option
Agreement, an employee of the Company (the "Participant"), of an option to
purchase, in whole or in part, on the terms provided herein and in the Company's
Amended and Restated 2000 Stock Incentive Plan (the "Plan"), a total of the
number of shares set forth in the attached Notice of Grant of Stock Option and
Option Agreement (the "Shares") of common stock, $0.01 par value per share, of
the Company ("Common Stock") at the price per Share set forth in the attached
Notice of Grant of Stock Option and Option Agreement. Unless earlier terminated,
this option shall expire on the tenth anniversary of the Grant Date (the "Final
Exercise Date").

         It is intended that the option evidenced by this agreement shall be an
incentive stock option as defined in Section 422 of the Internal Revenue Code of
1986, as amended and any regulations promulgated thereunder (the "Code"). Except
as otherwise indicated by the context, the term "Participant", as used in this
option, shall be deemed to include any person who acquires the right to exercise
this option validly under its terms.

2.       EXERCISE, VESTING SCHEDULE.

         This option shall be exercisable in full or in part at any time and
from time to time after the Grant Date. The right of exercise shall be
cumulative so that to the extent the option is not exercised at any time for the
total number of Shares covered by this option it shall continue to be
exercisable, in whole or in part, with respect to all Shares for which this
option has not been exercised, until the earlier of the Final Exercise Date or
the termination of this option under the Plan or this Section 2. This option
shall expire upon, and will not be exercisable after, the Final Exercise Date.

         (a)   FORM OF EXERCISE. Each election to exercise this option shall be
in writing, signed by the Participant, and received by the Company at its
principal office, accompanied by this agreement, and payment in full in the
manner provided in the Plan. The Participant may purchase less than the number
of Shares covered hereby, provided that no partial exercise of this option may
be for any fractional share or for fewer than ten whole shares.

         (b)   CONTINUOUS RELATIONSHIP WITH THE COMPANY REQUIRED. Except as
otherwise provided in this Section 2, this option may not be exercised unless
the Participant, at the time he or she exercises this option, is, and has been
at all times since the Grant Date, an employee, officer or director of, or
consultant or advisor to, the Company or any parent or subsidiary of the Company
as defined in Section 424(e) or (f) of the Code (an "Eligible Participant").

         (c)   TERMINATION OF RELATIONSHIP WITH THE COMPANY. If the Participant
ceases to be an Eligible Participant for any reason, then, except as provided in
paragraphs (d) and (e) below, the right to exercise this option shall terminate
three months after such cessation (but in no event after the Final Exercise
Date), PROVIDED THAT this option shall be exercisable only to the extent that
the Shares are not subject to the Purchase Option set forth in Section 3 below.

                                       50
<Page>

         (d)   EXERCISE PERIOD UPON DEATH OR DISABILITY. If the Participant dies
or becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior
to the Final Exercise Date while he or she is an Eligible Participant and the
Company has not terminated such relationship for "cause" as specified in
paragraph (e) below, this option shall be exercisable, within the period of one
year following the date of death or disability of the Participant, by the
Participant (or, in the case of death, by an authorized transferee); PROVIDED
THAT (1) this option shall be exercisable only to the extent that this option
was exercisable by the Participant on the date of his or her death or disability
and (2) this option shall be exercisable only to the extent that the Shares are
not subject to the Purchase Option set forth in Section 3 below and (3) this
option shall not be exercisable after the Final Exercise Date.

         (e)   DISCHARGE FOR CAUSE. If the Participant, prior to the Final
Exercise Date, is discharged by the Company for "cause" (as defined in Section 3
below), the right to exercise this option shall terminate immediately upon the
effective date of such discharge. The Participant shall be considered to have
been discharged for "cause" if the Company determines, within 30 days after the
Participant's resignation, that discharge for cause was warranted.

3.       PURCHASE OPTION.

         The Participant agrees that the Shares purchased upon the exercise of
this option shall be subject to the Purchase Option set forth in this Section 3
and the restrictions on transfer set forth in Section 5 of this Agreement.

         In the event that the Participant ceases to be an Eligible Participant
for any reason or no reason, with or without cause, prior to January 3, 2005,
the Company shall have the right and option (the "Purchase Option") to purchase
from the Participant, for the same price per share as paid by the Participant
for such Shares (the "Option Price"), some or all of the Unvested Shares (as
defined below). For the purposes of this Agreement, "cause" for termination
shall be deemed to exist upon a reasonable determination by the Company of
willful misconduct by the Participant or willful failure by the Participant to
perform his responsibilities to the Company (including, without limitation, a
material breach by the Participant of any employment, consulting, advisory,
nondisclosure, noncompetition or other similar agreement between the Participant
and the Company). The Participant shall be considered to have been discharged
for "cause" if the Company determines, within 30 days after the Participant's
resignation, that discharge for cause was warranted.

         "Unvested Shares" means the total number of Shares multiplied by the
Applicable Percentage at the time the Purchase Option becomes exercisable by the
Company. The "Applicable Percentage" shall be:

         (1)   zero percent (0%), if in connection with or within 24 months
         subsequent to a change in control (as defined below) the Participant's
         employment with the Company is terminated by the Company without cause
         or by the Participant for good reason (as defined below), with ten (10)
         days prior written notice given by the Participant to the Company in
         the case of termination by the Participant for good reason; and

         (2)   if the Participant ceases to be an Eligible Participant for
               reasons other than as applicable under clause 3 (1) above, (i)
               100% less 2.08334% for each full one month of the Participant
               being an Eligible Participant from and after January 3, 2001 and
               less an additional 25% if, after the Grant Date, the closing
               price of the Common Stock has been $10 or more (as quoted on the
               NASDAQ National Market or on such other exchange or market on
               which the Common Stock is then traded, if not traded on the
               NASDAQ National Market, and as determined by the Company's Board
               of Directors, in their sole discretion, if the Common Stock is
               not traded on any market or exchange) for any twenty consecutive
               trading days and less an additional 25% if, after the Grant Date,
               the closing price of the Common Stock has been $20 or more
               (determined as set forth above) for any twenty consecutive
               trading days; and (ii) 0% on and after January 3, 2005;

                                       51
<Page>

For the purposes of this Agreement, "good reason" shall mean the occurrence,
without the Participant's prior written consent, of any of the events or
circumstances set forth in clauses (i) through (vi) below. Notwithstanding the
occurrence of any such event or circumstance, such occurrence shall not be
deemed to constitute good reason if, prior to the date of termination, such
event or circumstance has been fully corrected and the Participant has been
reasonably compensated for any losses or damages resulting therefrom (provided
that such right of correction by the Company shall only apply to the first
notice of termination at the election of the Participant for good reason).

               (i)     Any significant diminution in the Participant's duties,
responsibilities or authority in effect immediately prior to the earliest to
occur of (A) the date on which a change in control of the Company occurs, (B)
the date of the execution of an initial written agreement or instrument
providing for a change in control of the Company or (C) the date of the adoption
by the Board of a resolution providing for a change in control of the Company
(with the earliest to occur of such dates referred to herein as the "Measurement
Date").

               (ii)    Any reduction in the annual base salary as in effect on
the Measurement Date or as the same may be increased from time to time
thereafter.

               (iii)   The failure by the Company to (A) continue in effect any
material compensation or benefit plan or program (each, a "Benefit Plan") in
which the Participant participates or which is applicable to the Participant
immediately prior to the Measurement Date, unless an equitable arrangement
(embodied in an ongoing substitute or alternative plan or reasonable cash
compensation in lieu thereof) has been made with respect to such plan or
program, (B) continue the Participant's participation in a Benefit Plan (or in
such substitute or alternative plan or make reasonable cash compensation in lieu
thereof) on a basis not materially less favorable, both in terms of the amount
of benefits provided and the level of the Participant's participation relative
to other participants, than the basis existing immediately prior to the
Measurement Date or (C) award cash bonuses to the Participant in amounts and in
a manner substantially consistent with past practice in light of the Company's
financial performance.

               (iv)    A change by the Company in the location at which the
Participant performs the Participant's principal duties for the Company to a new
location that is either (A) outside a radius of 35 miles from the Participant's
principal residence immediately prior to the Measurement Date or (B) more than
30 miles from the location at which the Participant performs his or her
principal duties for the Company immediately prior to the Measurement Date and
(C) which results in an increase of at least fifteen miles in the Participant's
daily commuting distance; or a requirement by the Company that the Participant
travel on Company business to a substantially greater extent than required
immediately prior to the Measurement Date.

               (v)     The failure by the Company to obtain the agreement, in a
form reasonably satisfactory to the Participant, from any successor to the
Company to assume and agree to perform this Agreement to the same extent that
the Company would be required to perform it if no such succession had taken
place.

               (vi)    Any failure of the Company to pay or provide to the
Participant any portion of the Participant's compensation or benefits due under
any Benefit Plan within seven days of the date such compensation or benefits are
due, or any material breach by the Company of any employment agreement with the
Participant.

         For purposes of this Agreement, "change in control" shall mean the
occurrence of any of the events or circumstances set forth in clauses (I)
through (IV) below.

                                       52
<Page>

                       (I)    the acquisition by an individual, entity or group
(within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act")) (a "Person") of beneficial
ownership of any capital stock of the Company if, after such acquisition, such
Person beneficially owns (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) 50% or more of either (A) the then-outstanding shares of Common
Stock (the "Outstanding Common Stock") or (B) the combined voting power of the
then-outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Voting Securities") provided,
however, that for such purposes, the following acquisitions shall not constitute
a Change in Control: (w) any acquisition directly from the Company, (x) any
acquisition by the Company, (y) any acquisition by any employee benefit plan (or
related trust) sponsored or maintained by the Company or any corporation
controlled by the Company, or (z) any acquisition by any corporation pursuant to

                       (II)   Individuals who, as of the date hereof, constitute
the members of the Board (the "Incumbent Directors") ceasing for any reason to
constitute at least a majority of the Board; provided, however, that any
individual becoming a director subsequent to the date hereof whose election, or
nomination for election by the Company's stockholders, was approved by a vote of
at least a majority of the Incumbent Directors then in office shall be deemed to
be an Incumbent Director (except that this proviso shall not apply to any
individual whose initial election as a director occurs as a result of an actual
or threatened election contest with respect to the election or removal of
directors or other actual or threatened solicitation of proxies or consents by
or on behalf of a Person other than the Board).

                       (III)  The consummation of a reorganization,
recapitalization, merger or consolidation involving the Company or a sale or
other disposition of all or substantially all of the assets of the Company (a
"Business Combination"), unless, immediately following such Business
Combination, each of the following three conditions is satisfied: (A) all or
substantially all of the individuals and entities who were the beneficial owners
of the Outstanding Common Stock and Outstanding Voting Securities immediately
prior to such Business Combination beneficially own, directly or indirectly,
more than 50% of the then-outstanding shares of common stock and the combined
voting power of the then-outstanding voting securities entitled to vote
generally in the election of directors, respectively of the resulting or
acquiring corporation in such Business Combination (which shall include, without
limitation, a corporation which as a result of such transaction owns the Company
or substantially all of the Company's assets either directly or through one or
more subsidiaries) (such resulting or acquiring corporation is referred to
herein as the "Acquiring Corporation") in substantially the same proportions as
their ownership, immediately prior to such Business Combination, of the
Outstanding Common Stock and Outstanding Voting Securities, respectively, (B) no
Person (excluding the Acquiring Corporation or any employee benefit plan (or
related trust) maintained or sponsored by the Company or the Acquiring
Corporation) beneficially owns, directly or indirectly, 50% or more of the then
outstanding shares of common stock of the Acquiring Corporation or of the
combined voting power of the then-outstanding voting securities of such
corporation (except to the extent that such ownership existed prior to the
Business Combination) and (C) a majority of the members of the board of
directors of the Acquiring Corporation were Incumbent Directors at the time of
the execution of the initial agreement, or of the action of the Board, providing
for such Business Combination.

                       (IV)   Approval by the stockholders of the Company of a
complete liquidation or dissolution of the Company.

4.       EXERCISE OF PURCHASE OPTION AND CLOSING.

         (a)   The Company may exercise the Purchase Option by delivering or
mailing to the Participant (or his estate), within 60 days after the Participant
ceases to be an Eligible Participant, a written notice of exercise of the
Purchase Option (the "Notice of Exercise"). The Notice of Exercise shall specify
the number of Shares to be purchased. If and to the extent the Purchase Option
is not so exercised by the giving of the Notice of Exercise within such 60-day
period, the Purchase Option shall automatically expire and terminate effective
upon the expiration of such 60-day period.

                                       53
<Page>

         (b)   Within 10 days after receipt by the Participant of the Notice of
Exercise, the Participant (or his estate) shall tender to the Company at its
principal offices the certificate or certificates representing the Shares which
the Company has elected to purchase in accordance with the terms of this
Agreement, duly endorsed in blank or with duly endorsed stock powers attached
thereto, all in form suitable for the transfer of such Shares to the Company.
Immediately upon receipt of such certificate or certificates, the Company shall
(i) pay to the Participant the aggregate Option Price for such Shares and (ii)
issue to the Participant one or more certificates registered in the name of the
Participant for that number of Shares not purchased by the Company pursuant to
such Notice of Exercise.

         (c)   The Option Price may be payable, at the option of the Company, in
cancellation of all or a portion of any outstanding indebtedness of the
Participant to the Company or in cash (by certified check) or both.

         (d)   The Company shall not purchase any fraction of a Share upon
exercise of the Purchase Option, and any fraction of a Share resulting from a
computation made pursuant to Section 3 of this Agreement shall be rounded to the
nearest whole Share (with any one-half Share being rounded upward).

5.       RESTRICTIONS ON TRANSFER.

         The Participant shall not sell, assign, transfer, pledge, hypothecate
or otherwise dispose of, by operation of law or otherwise, (collectively
"transfer") any Shares, or any interest therein, that are subject to the
Purchase Option or with respect to which the Purchase Option may become
exercisable, except that the Participant may transfer such Shares to or for the
benefit of any spouse, child or grandchild, or to a trust for any of their
benefit, PROVIDED that such Shares shall remain subject to this Agreement
(including, without limitation, the restrictions on transfer set forth in this
Section 5 and the Purchase Option) and such permitted transferee shall, as a
condition to such transfer, deliver to the Company a written instrument
confirming that such transferee shall be bound by all of the terms and
conditions of this Agreement.

6        WITHHOLDING.

         No Shares will be issued pursuant to the exercise of this option unless
and until the Participant pays to the Company, or makes provision satisfactory
to the Company for payment of, any federal, state or local withholding taxes
required by law to be withheld in respect of this option.

         The Participant acknowledges that he has been informed of the
availability of making an election in accordance with Section 83(b) of the
Internal Revenue Code of 1986, as amended; that such election must be filed with
the Internal Revenue Service within 30 days of the transfer of shares to the
Participant; and that the Participant is solely responsible for making such
election.

7.       NONTRANSFERABILITY OF OPTION.

         This option may not be sold, assigned, transferred, pledged or
otherwise encumbered by the Participant, either voluntarily or by operation of
law, except by will or the laws of descent and distribution, and, during the
lifetime of the Participant, this option shall be exercisable only by the
Participant.

8.       DISQUALIFYING DISPOSITION.

         If the Participant disposes of Shares acquired upon exercise of this
option within two years from the Grant Date or one year after such Shares were
acquired pursuant to exercise of this option, the Participant shall notify the
Company in writing of such disposition.

or to pay dividends to, any transferee to whom any such Shares shall have been
sold or transferred in violation of any of the provisions set forth in this

Exhibit 10.36

                                                        May 24, 2001

Mr. Gary Kiaski
183 Oakcreek Blvd.
Scotts Valley, California  95066

Dear Gary:

I am writing to confirm our agreement regarding the termination of your
employment at Innoveda.

Effective August 3, 2001, you have resigned from the employment of, and from all
offices and directorships of, Innoveda, Inc. and each of its subsidiary
companies. On August 3, 2001, Innoveda will pay to you $215,000, representing
one year of your current base salary. We will withhold from this payment taxes
and any other appropriate deductions. If you elect to continue medical and
dental insurance coverage under COBRA, Innoveda will pay the COBRA cost for the
period of August 3, 2001 through July 31, 2002. We reserve the right to change
your medical coverage from the indemnity plan to the Preferred Provider
Organization (PPO) plan. If you obtain other employment that offers medical
and/or dental coverage, you must promptly notify Innoveda and obtain that
coverage from your new employer and discontinue coverage from Innoveda under
COBRA.

Also, if you elect to exercise the stock option granted to you on November 23,
1998, Innoveda will loan to you $62,766 to be used as payment for the exercise
of that stock option (there will be 128,094 shares vested on August 3, 2001 and
the exercise price is $.49 per share). This loan will be a full recourse loan at
market rate interest (as determined by our bank), will require payment of only
interest until August 2, 2002 and the entire principal amount of the loan and
all unpaid interest will be due on August 2, 2002. We will hold the stock that
you acquire on the exercise of your stock option as security for the loan and
you (and your wife if you elect to have that stock issued in both names) will
sign a promissory note and stock pledge agreement in form and substance
satisfactory to Innoveda's lawyers.
