Calypto Design Systems was embraced by Mentor Graphics this week. Founded in 2002, the company was born out of discussions between founder Devadas Varma and Dado Banatao, partner at Tallwood Venture Capital. By early 2005, it had raised $22 million in venture capital, and had 42 employees, 18 with PhDs. It was tackling equivalence checking (SLEC) between ESL and RTL design representations.
In 2011, Mentor bought a 51% interest in the company and sold Calypto its Catapult-C synthesis technology, which seemed like a good match to their SLEC tool. With Calypto’s growing success, it was natural that Mentor would pull them into their fold.
For several years, Calypto Design Systems and Real Intent have co-operated in support of verification flows for mutual customers. Both companies shared the same distributor is Korea.
One flow we had jointly announced was our Ascent Lint with their Catapult synthesizer. Catapult lets designers use industry standard ANSI C++ or SystemC to describe functional intent at the ESL level. From these high-level descriptions, Catapult automatically generates production quality RTL. Ascent Lint ensures Catapult-generated RTL code is lint clean and error free for a safe and reliable implementation flow from RTL to GDSII layout.
