Fujitsu to Provide Industry's First Comprehensive Environment for Statistical Timing Analysis for Submicron Designs

Timing Optimization Turn-around Times to be Reduced by up to 30 Percent

SUNNYVALE, Calif., July 21 // -- Fujitsu Microelectronics America, Inc. (FMA) announced that Fujitsu is the first semiconductor supplier to provide a comprehensive environment for statistical timing analysis for ASIC and COT customers. The new environment enables designers to reduce the design-optimization time in layout designs, by allowing them to calculate the circuit delays using statistical analysis of the impact of process variations.

The environment includes statistical static-timing-analysis tools developed together by Fujitsu Limited, Fujitsu VLSI Limited and Fujitsu Laboratories Limited, and cell libraries with process variations. The Anova Suite(TM), developed by Anova Solutions Inc., has been implemented in the environment in order to analyze process variations and characterize library cells.

"The ability to analyze the impact of process variations in deep-submicron technologies at the cell design stage is a significant breakthrough for ASIC and COT designers," said Yoshio Kuniyasu, senior director of SoC Design Engineering Center for Fujitsu Microelectronics America. "Fujitsu has teamed with Anova to provide a comprehensive environment developed to resolve this challenge. We are confident that our customers will realize significant reductions in timing optimization turn-around time as they implement the system."

Statistical timing-analysis techniques, which check if a circuit can function at a targeted frequency, are becoming a key DFM (Design For Manufacturing) requirement for resolving the challenges of the fabrication process during the design phase. Since process variations in transistors significantly affect cell delays and circuit delay in 90-nanometers and deeper submicron technologies, more accurate timing-analysis methodologies are needed to handle the variations.

Conventional static-timing-analysis methods often overestimate circuit delay, since they cannot handle delay variations caused by a process. In contrast, the statistical static-timing-analysis environment provided by Fujitsu can handle the delay variations of transistors statistically. This enables layout designers to estimate the circuit delay more accurately and optimize the circuit effectively so that it can run at the targeted frequency. Timing-overestimation problems are avoided, since the delay computation is completed in the presence of process variations. As a result, timing optimization turn-around time can be reduced by up to 30 percent.

Another feature of the environment is that it is integrated in Fujitsu's reference design flow. Designers can invoke the easy-to-use environment seamlessly in the original flow.


Fujitsu's environment for statistical timing analysis will be available to ASIC and COT customers in October 2006. Fujitsu will provide the environments for both 90nm and 65nm technology, and will continue to build more advanced design environments by establishing close partnerships with EDA vendors. The new design kit will also be available in October 2006.
