SANTA CLARA, USA: Calypto Design Systems, a leader in sequential analysis technology, has unveiled a new version of its SLEC System-HLS (High Level Synthesis) product that is fully integrated with Cadence Design Systems' new C-to-Silicon Compiler high-level synthesis technology.

Calypto and Cadence joined forces to deliver a dynamic, system-level design solution that dramatically increases designer productivity by automating the C-to-Silicon Compiler and SLEC (Sequential Logic Equivalence Checker) verification flow. SLEC System-HLS, based on Calypto's patented sequential analysis technology, verifies that the register transfer level (RTL) code generated by C-to-Silicon Compiler is functionally equivalent to the original SystemC code.

Hisaharu Miwa, general manager of Design Technology Division, LSI Product Technology Unit, Renesas Technology Corp., whose design team was an early adopter of the integrated Cadence/Calypto flow, says: "The industry requires formal equivalence checking in high-level synthesis flows. We found that the Calypto SLEC System-HLS and Cadence C-to-Silicon Compiler integration provides us an excellent system-level formal verification flow, saving our design team significant time and maximizing productivity."

SLEC is the semiconductor industry's only functional verification solution to formally verify equivalence between electronic system level (ESL) models and RTL implementations. SLEC System-HLS comprehensively verifies the output of C-to-Silicon Compiler, eliminating the need for many time-consuming simulation regressions.

"Calypto's SLEC System-HLS product has become the standard for system-level equivalence checking," said Michael McNamara, VP/GM of the Cadence C-to-Silicon Compiler technology incubator. "Adding a tight integration between SLEC System-HLS and C-to-Silicon Compiler to our design and verification flows built around both the Encounter digital IC design and Incisive verification platforms enables Cadence to provide customers with a comprehensive solution for system level design and verification."

SLEC System-HLS is an added option to SLEC System. SLEC System-HLS tightly integrates SLEC System into HLS design flows and includes solutions for Cadence Design Systems' C-to-Silicon Compiler, Forte Design Systems' Cynthesizer and Mentor Graphics' Catapult-C. Each HLS vendor solution is sold separately and priced at $50,000 for a one-year, time-based license.
