  Item 2. Acquisition or Disposition of Assets.
  
       Pursuant to the Agreement and Plan of Merger (the "Merger Agreement") by
  and among, OrCAD, Inc., a  Delaware corporation ("OrCAD"), OCA Merger
  Corporation, an Oregon corporation and wholly-owned subsidiary of OrCAD ("Merger
  Sub"), and MicroSim Corporation, a California corporation ("MicroSim"), dated as
  of October 13, 1997,  Merger Sub was merged with and into MicroSim (the
  "Merger") effective as of January 20, 1998 (the "Effective Time").  In the
  Merger, all of the issued and outstanding shares of MicroSim Common Stock and
  all of the outstanding options and other rights to acquire MicroSim Common Stock
  were converted into and exchanged for shares of OrCAD Common Stock.  The
  aggregate number of shares of OrCAD Common Stock issued in the Merger was
  2,427,714 shares, including a total of 202,081 shares issued in exchange for all
  outstanding vested and unvested options and other rights to purchase shares of
  MicroSim Common Stock.  As prescribed under the Merger Agreement, OrCAD withheld
  ten percent (10%)of the shares of OrCAD Common Stock issued in the Merger (the
  "Escrow Shares") and will deliver these to First National Trust Association as
  escrow agent.  The Escrow Shares will be held for a period of one year during
  which time they will be subject to claims by OrCAD to satisfy MicroSim's
  obligations under the Merger Agreement.  The amount of consideration paid in the
  Merger was determined through arms-length negotiations between officers of OrCAD
  and MicroSim.
  
       The terms of the transaction were approved by the Boards of Directors and
  stockholders of OrCAD, Merger Sub and MicroSim. As a result of the Merger,
  MicroSim has become a wholly-owned subsidiary of OrCAD. OrCAD intends to
  continue the existing product development operations of MicroSim at its facility
  in Irvine, California. In connection with the Merger, the former Chairman,
  President, Chief Executive Officer and principal stockholder of MicroSim,
  Wolfram H. Blume, will be elected to the Board of Directors of OrCAD. Mr. Blume
  has also entered into an agreement with OrCAD pursuant to which he will provide
  advisory services to OrCAD on a part time basis for a period of two years after
  the Effective Time. The agreement contains non-compete and a non-solicitation
  provisions applicable for three years following the Effective Time. As a result
  of the Merger, Mr. Blume now owns approximately 19.4% of the shares of OrCAD
  Common Stock issued and outstanding after the Merger.
