Cadence C-to-Silicon Compiler Supported in Fujitsu Semiconductor’s ASIC Flow for System Realization


C-to-Silicon Compiler Connects High-Level Synthesis to Production Implementation to Deliver Predictable IP Development from TLM to GDSII

SAN JOSE, Calif., Cadence Design Systems, Inc. (NASDAQ: CDNS), a global leader in electronic design innovation, today announced that Fujitsu Semiconductor Limited now supports the Cadence® C-to-Silicon Compiler for high-level synthesis in ASIC design flows. C-to-Silicon Compiler is the only high-level synthesis tool that embeds production RTL synthesis--Cadence Encounter® RTL Compiler--to generate implementation-ready RTL for the target application. This delivers a predictable flow from transaction-level model (TLM) to GDSII, with the ability to apply ECO patches throughout, effectively reducing System Realization time. A separate Fujitsu subsidiary has already begun using C-to-Silicon Compiler in production on a large-scale design.

“Our customers want to adopt high-level synthesis based on SystemC in order to increase their design and verification productivity, and enable wider re-use of their IP,” said Takashi Hasegawa, general manager of SoC Solutions Division, Fujitsu Semiconductor Limited. “We have carefully evaluated Cadence C-to-Silicon Compiler--which delivers the capability to handle ECOs at any time--and its contribution to rapid system development. As a result, we have decided to support its use by our customers, and we are planning to use it internally on a production design.”

C-to-Silicon Compiler raises the design abstraction level so that verification can be more productive and the design can be more readily re-used across varying configurations in end devices. The unique incremental synthesis capabilities that C-to-Silicon Compiler offers integrate tightly with Silicon Realization technologies, including

Encounter RTL Compiler, Encounter Conformal® ECO and Conformal LEC, to deliver a predictable TLM-to-GDS flow with full ECO capabilities.

“With our innovative C-to-Silicon Compiler technology, engineers can dramatically accelerate product development for various applications and derivative designs,” said Michał Siwiński, product management group director for System Realization at Cadence. “We expect Fujitsu Semiconductor to benefit significantly from the time-to-market benefits inherent in highly reusable product design and verification at a raised level of abstraction.”

The Cadence System Realization is a key component of the EDA360 vision, which emphasizes the need for rapid, applications-driven system development.
