Calypto buys Mentor Graphics' ESL design software

Calypto Design Systems Inc. buys Mentor Graphics Corp.'s Catapult C Synthesis, an electronic system level (ESL) design software product that is said to create better integrated ESL hardware realisation flow in combination with Calypto's SLEC System-HLS verification tool.

The details of the transaction were not disclosed.

"This is a great deal for Calypto," said Gary Smith, chief analyst at Gary Smith EDA, in a statement issued by Calypto. "They are clearly one of the companies on the rise in ESL, and this gives them the chance to offer a compelling power-optimised C to RTL flow if they can integrate all the pieces."

ESL methodologies, which enable chip designers to work at a higher level of abstraction, has for years been considered the next evolutionary rung in chip design and EDA. Migration to ESL methodologies has been gaining traction, but at a slower pace than many observers had expected.

According to Smith, ESL adoption grew by 13 per cent last year, and his firm is forecasting a compound annual growth rate for ESL adoption of nearly 28 per cent over the next five years.

In an interview with EE Times' Doug Aitelli, Calypto's CEO, said the company determined that to increase ESL adoption, it needed to get all of the different pieces of an integrated ESL design flow "under one roof." Combining C synthesis with Calypto's sequential verification and power optimisation products means Calypto has not integrated the majority of the pieces required for an integrated ESL flow, Aitelli said.

Aitelli emphasized that Calypto remains an independent company, supporting many different tools and industry-wide interoperability. "This doesn't change our outward stance on how we work with other parts of the industry," Aitelli said.

Despite the spinoff of Catapult C, Brian Derrick, vice president of marketing at Mentor, said the company remains deeply committed to ESL. Derrick said that Calypto's ownership of Catapult C would spur broader adoption of high-level synthesis, one part of the ESL flow. Broader adoption will, in turn, increase Mentor's market opportunity for ESL virtual prototyping environments led by the company's Vista product, Derrick said.

"This is just one component of our overall ESL strategy," Derrick said.

Brett Cline, vice president of sales and marketing for Forte Design Systems Inc., a leading supplier of high-level synthesis software that competes with Catapult C, described the Catapult C deal as "yet another example of how the big EDA companies like Mentor cannot afford to continue to give away products for very low prices without taking a hit to their bottom line."

Cline added that he interpreted the deal as a signal that Mentor saw the Catapult business losing momentum to the point where the cost savings of moving the employees off of the books to Calypto outweighed the revenue that the product produced.
