To Our Clients:

     Enclosed for your consideration is an Offer to Purchase dated April 30,
2002 (the "Offer to Purchase") and the related Letter of Transmittal (which
together, as each may be amended, supplemented or otherwise modified from time
to time constitute the "Offer") in connection with the offer by Mentor Graphics
Corporation, an Oregon corporation ("Mentor Graphics"), through Indiana Merger
Corporation, a Delaware corporation ("Purchaser" and, together with Mentor
Graphics, "Mentor") and a wholly-owned subsidiary of Mentor Graphics, to
purchase for cash all of the shares of common stock, par value $0.01 per share
(the "Shares"), of Innoveda, Inc., a Delaware corporation (the "Company"), at a
purchase price of $3.95 per Share, net to the seller in cash, without interest
thereon, upon the terms and subject to the conditions set forth in the Offer to
Purchase and the Letter of Transmittal.

     We are the holder of record of Shares held for your account. A tender of
such Shares can be made only by us as the holder of record and pursuant to your
instructions. The Letter of Transmittal is furnished to you for your information
only and cannot be used by you to tender Shares held by us for your account.

     We request instructions as to whether you wish us to tender any or all of
the Shares held by us for your account, upon the terms and subject to the
conditions set forth in the Offer to Purchase and the Letter of Transmittal.

     Your attention is invited to the following:

          1.  The tender price is $3.95 per Share, net to you in cash.

          2.  The Offer is being made for all of the outstanding Shares.

          3.  The Offer is conditioned upon, among other things, (1) there being
     validly tendered and not withdrawn immediately prior to the expiration of
     the Offer a number of Shares that represents at least a majority of the
     total number of outstanding Shares on a fully diluted basis on the date of
     purchase and (2) the expiration or termination of any and all waiting
     periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
     amended, and the regulations thereunder. The Offer is also subject to
     certain other conditions described in Section 16 of the Offer to Purchase.
     The Offer is not conditioned upon Mentor obtaining financing.


          4.  The Offer is being made pursuant to the Agreement and Plan of
     Merger, dated as of April 23, 2002 (the "Merger Agreement"), among the
     Company, Mentor Graphics and Purchaser. The Merger Agreement provides for,
     among other things, the making of the Offer by Mentor, and further provides
     that, as soon as practicable following consummation of the Offer, Purchaser
     will be merged with and into the Company (the "Merger") with the Company
     continuing as the surviving corporation and a wholly-owned subsidiary of
     Mentor Graphics.

          5.  The Board of Directors of the Company by unanimous vote of all
     directors present at a meeting of the Company's Board of Directors held on
     April 23, 2002, (1) determined that the Offer and the Merger are fair to
     and in the best interests of the stockholders of the Company, (2) approved
     and adopted the Merger Agreement and the transactions contemplated thereby,
     including the Offer and the Merger and (3) recommended that the Company's
     stockholders accept the Offer and tender their Shares pursuant to the
     Offer.

          6.  THE OFFER AND WITHDRAWAL RIGHTS EXPIRE AT 12:00 MIDNIGHT, NEW YORK
     CITY TIME, ON TUESDAY, MAY 28, 2002, UNLESS THE OFFER IS EXTENDED.

          7.  Any stock transfer taxes applicable to a sale of Shares to the
     Purchaser will be borne by Purchaser, except as otherwise provided in
     Instruction 6 of the Letter of Transmittal.

     If you wish to have us tender any or all of your Shares, please so instruct
us by completing, executing, detaching and returning to us the instruction form
on the detachable part hereof. An envelope to return your instructions to us is
enclosed. If you authorize the tender of your Shares, all such Shares will be
tendered unless otherwise specified on the detachable part hereof. Your
instructions should be forwarded to us in ample time to permit us to submit a
tender on your behalf by the expiration of the Offer.

     The Offer is not being made to, nor will tenders be accepted from or on
behalf of, holders of Shares in any jurisdiction in which the making of the
Offer or acceptance thereof would not be in compliance with the laws of such
jurisdiction.

     Payment for Shares purchased pursuant to the Offer will in all cases be
made only after timely receipt by Wilmington Trust Company (the "Depositary") of
(a) certificates representing the Shares tendered or timely confirmation of the
book-entry transfer of such Shares into the account maintained by the Depositary
at The Depository Trust Company (the "Book-Entry Transfer Facility"), pursuant
to the procedures set forth in Section 4 of the Offer to Purchase, (b) the
Letter of Transmittal, properly completed and duly executed, with any required
signature guarantees or an Agent's Message (as defined in the Offer to
Purchase), in connection with a book-entry delivery, and (c) any other documents
required by the Letter of Transmittal. Accordingly, payment may not be made to
all tendering stockholders at the same time depending upon when certificates for
or confirmations of book-entry transfer of such Shares into the Depositary's
account at the Book-Entry Transfer Facility are actually received by the
Depositary.
