Cadence was involved in a 6-year-long legal dispute[16] with Avanti Corporation, in which Cadence claimed Avant! stole Cadence code, and Avant! denied it. According to Business Week "The Avant! case is probably the most dramatic tale of white-collar crime in the history of Silicon Valley".[16] The Avant! executives eventually pleaded no contest and Cadence received several hundred million dollars in restitution. Avant! was then purchased by Synopsys, which paid $265 million more to settle the remaining claims.[17] The case resulted in a number of legal precedents.[18]
