Item 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On September 30, 1998, Cadence Design Systems, Inc., a Delaware 
corporation (the "Registrant"), acquired all of the outstanding capital stock 
of Ambit Design Systems, Inc., a California corporation ("Ambit"), in 
exchange for $260 million in cash from the Registrant's working capital (the 
"Acquisition"). A portion of the funds used to finance the Acquisition may 
derive from the Registrant's credit facility governed by that certain Credit 
Agreement, dated as of September 29, 1998, by and among the Registrant, ABN 
AMRO Bank N.V., as agent, and certain banks described therein. The 
Acquisition was effected by means of a reverse triangular merger pursuant to 
which a wholly-owned subsidiary of the Registrant merged with and into Ambit, 
with Ambit as the surviving company. As a result of such merger, Ambit became 
a wholly-owned subsidiary of the Registrant. The consideration paid by the 
Registrant for Ambit's outstanding capital stock was negotiated at arm's 
length between the parties on the basis of the Registrant's assessment of the 
value of Ambit and its capital stock, following an investigation of, and 
discussions with Ambit and its representatives concerning Ambit and its 
business and prospects. To the Registrant's knowledge, there is no material 
relationship between any of the former shareholders of Ambit and the 
Registrant or any of its affiliates, any director or officer of the 
Registrant, or any associate of any such director or officer.
