Cadence Design Systems said it has filed new
evidence in its ongoing lawsuit against Avant, claiming to have proof
that the design-automation rival directly copied its Design Framework II.
"Aquarius would not exist as a workable product without Avant's
misappropriation of Cadence trade secrets, and Aquarius therefore should
be enjoined," according to the filing made this week in federal court in San Jose, Calif.
Cadence urged the federal court to let its civil case against Avant proceed,
and the San Jose company said it plans to seek $1.2 billion in damages once the trial
Immediately, Avant denied Cadence's claims, saying there is no copied
code in Aquarius place-and-route design software. The Fremont,
Calif.-based electronic-design-automation supplier accused Cadence of
acting irresponsibly in its suit and public statements on the legal dispute.
"The allegations in today's filing are the same kind of baseless charges
Cadence has been making for months," said David Stanley, general counsel
for Avant. "We will continue to refute
these charges and we remain confident Avant will prevail in the courtroom

Cadence has asked the San Jose federal court to lift a stay that has blocked

hopeful we can have our day in court in front of a jury as quickly as possible
so justice can be fully served in this matter."
Cadence maintains in its new filing that it has uncovered evidence of copied
software after six months of technical analysis of Aquarius products by
"Once again, there is clear evidence of literal copying of ordinary
unrestricted English text" from Cadence's code into Avant's Aquarius
software, according to Randall Davis, a professor at Massachusetts Institute
of Technology who participated in the analysis of the
place-and-route integrated circuit design software.
Cadence maintains the analysis has uncovered three main areas of
copied code from its place-and-route and database products. The court
filing said these areas are compaction, database, and human-interface
