IDT Adopts Simplex's VoltageStorm SoC

SUNNYVALE, Calif., Nov. 26 /PRNewswire/ -- Simplex Solutions, Inc. (Nasdaq: SPLX - news), a leading provider of software and services for the design and verification of integrated circuits (ICs), today announced that leading communications integrated circuit provider IDT (Nasdaq: IDTI - news) has adopted Simplex's VoltageStorm(TM) SoC power grid verification software as a standard part of IDT's next-generation design flow for its value-added communications ICs. IDT will use VoltageStorm SoC -- the leading power grid verification solution -- to verify the impact of deep-submicron effects -- such as power grid IR (voltage) drop and electromigration risk, on IDT's advanced semiconductor products targeted at communications infrastructure applications.

"Power grid verification is an essential step for designs targeted at and below 0.13 micron," said Anwar Hasan, director of design automation at IDT. "We selected Simplex's VoltageStorm SoC because of the accuracy of the embedded transistor-level engine fueling the tool's fast, hierarchical power grid analysis and verification. With VoltageStorm SoC as part of our next-generation design flow, we're confident that we will be able to understand and account for the impact of voltage drop on our designs before tapeout."

Until the advent of deep-submicron process technologies, IR drop was considered a second- or third-order effect. Today's high-performance SoC designs, with their increasing chip size and number of integrated IP blocks, as well as decreasing power supply voltages, are at increased risk for IR drop-related failures due to the unpredictable flow of power in and around embedded blocks. At 0.13 micron, IR drop has become a signal integrity issue, and can have direct impact on a chip's timing. Accordingly, SoC designers require verification tools with an embedded transistor-level engine for accuracy combined with automated, hierarchical model generation to rapidly provide a solution to the timing, power and signal-integrity issues of 0.13-micron design.

"Leading-edge companies, like IDT, understand that at ultra-deep-submicron technologies, IR drop is a first-order effect that can have broad-ranging impact on a chip's timing and reliability," said Jim Bailey, general manager of Simplex's SoC verification business. "We are very pleased to be able to provide IDT with a solution to this critical problem, helping them to achieve first-silicon success for their advanced process technology designs."
