NECs CyberWorkBench and DeFacTo’s SIGNOFF Interoperate Towards A Complete C to RTL Design Solution Including DFT

Grenoble, France, September 10th. NEC and DeFacTo Technologies S.A. today announced that DeFacTo Technologies’ SIGNOFF has been integrated into NEC’s CyberWorkBench C-based VLSI design suite.

Tightly integrating CyberWorkBench and SIGNOFF provides unique capabilities in the market. Among many, it allows users to explore different architectural scenarios from C to RTL including DFT criteria.

CyberWorkBench is a C-based electronic circuit design platform developed by NEC over the course of twenty years. CyberWorkBench is developed around the “All-in-C” paradigm that allows high level synthesis and verification of any ANSI-C or SystemC program generating high quality circuits.

SIGNOFF is an RTL DFT evaluation and enhancement platform. It helps reaching high DFT quality levels in a more predictable timeframe and allows earlier DFT analysis & enhancement at the block, the IP core and the top levels and makes possible RTL DFT exploration including test compression, memory/logic BIST & JTAG.

“Integrating SIGNOFF into CyberWorkBench will provide new capabilities to our users by including DFT analysis at the earliest design stages, enabling them to generate ‘DFT friendly’ RTL” said Kazutoshi Wakabayashi, Senior Manager, Embedded Systems Solution Division, NEC. “We were extremely pleased to learn how easy it is to use SIGNOFF and how  smooth and easy the integration with CyberWorkBench went”.

“We are excited about our collaboration with NEC. SIGNOFF has proven capabilities to generate DFT friendly RTL designs. With this collaboration with NEC for the first time in the market, a user will have full confidence that a generated RTL is a 100% DFT friendly”, said Chouki Aktouf CEO of DeFacTo Technologies. Mr. Aktouf added, “CyberWorkBench users will rapidly see lower NRE due to DFT problems when generating RTL designs.”
