S3 Graphics Chooses Sequence's CoolTime For Advanced Power Grid Analysis At 90nm
S3 Graphics, a Via Technologies joint venture company, has adopted Sequence Design's CoolTime for dynamic voltage drop analysis and optimization of its next-generation 90nm products.
CoolTime has displaced competing power-grid analysis tools according Michael Shiuan, vice president of engineering for S3 Graphics. "CoolTime demonstrated excellent improvement in voltage drop with significantly fewer decoupling capacitors on our high-end graphics processor without impacting timing or signal integrity," he said.
Shiuan added that CoolTime offers S3 significant accuracy and time-to-market advantages as it is the only tool with integrated timing and signal-integrity engines, and is highly integrated with the company's existing Cadence and Synopsys flows. "Due to the good results demonstrated by CoolTime, we are planning to use it for our next-generation, multimillion gate design," Shiuan said.
CoolTime replaces point analysis tools that can only analyze one electrical effect at a time. By integrating the analysis of power, electromigration, voltage drop, timing, and signal integrity into a concurrent database, it reduces design and analysis iterations up to four times. As a signoff solution independent of the design implementation tools, CoolTime enables designers to signoff with confidence and ensure first-silicon success. CoolTime has proven accuracy with silicon and SPICE, and the performance and capacity to handle multimillion gate designs, thus making it an ideal signoff solution for nanometer SoC designs.
"World-class companies such as S3 are confronting mounting challenges with low-power design at 90nm and below," said Vic Kulkarni, president and CEO of Sequence Design. "With CoolTime, we are providing industry-leading technology to tackle the concurrent issues of voltage drop, power, timing, and signal integrity to ensure rapid signoff with no impact on quality or time to market."
