Toshiba Standardizes on PrimeRail for Rail Signoff

Superior Performance and Accuracy, Combined with In-Design Early Analysis Boosts Design Teams' Productivity

MOUNTAIN VIEW, Calif., June 3, 2015 — (PRNewswire) — Highlights:

  • PrimeRail exceeded Toshiba's rigorous accuracy qualification criteria for static rail analysis
  • Toshiba saw 1.5X faster runtimes and 30 percent smaller memory footprint over the reference solution
  • Synopsys' In-Design seamless integration capabilities of PrimeRail and IC Compiler significantly improves turnaround time
  • Toshiba has deployed PrimeRail static signoff analysis globally in its implementation and signoff kit

Synopsys, Inc. (Nasdaq: SNPS) today announced that Toshiba Corporation has adopted and successfully deployed the Synopsys PrimeRail analysis tool as the rail signoff solution for static analysis. PrimeRail signoff will be used for all of Toshiba's product lines, including mixed signal, ASIC and memories.

"Rail analysis has become a critical requirement for advanced technology nodes," said Mr. Kazunari Horikawa, senior manager of Design Technology Development Department, Mixed Signal IC Division at Toshiba Corporation Semiconductor and Storage Products Company. "Synopsys PrimeRail provides 1.5X faster performance over the existing solution and accuracy that meets our stringent signoff requirements. It also offers an extensive set of features to support Toshiba's broad variety of design styles and technologies.  In-Design early analysis during design implementation made it easy for designers to build a robust power grid early. This early analysis combined with silicon proven accuracy and faster performance allows us to save multiple weeks in our schedules and sign off with confidence."

Built on Synopsys' PrimeTime® timing and power engines, PrimeRail leverages industry-proven technology to provide SPICE-accurate static and dynamic rail analysis. The multi-threaded and highly scalable engine is able to analyze 100 million instances overnight, while native support for multi-voltage, complex I/O cells, analog blocks and external IP provides full chip analysis capabilities. Seamless IC Compiler™ and PrimeRail In-Design integration makes power and voltage drop analysis easily accessible during implementation to help address PG network weaknesses early in the flow, and to minimize costly last-minute engineering change orders (ECOs).

"Toshiba put PrimeRail through a rigorous qualification process on multiple production designs at Toshiba and it consistently exceeded Toshiba's signoff criteria," said Bijan Kiani, vice president of marketing for Synopsys' Design Group. "With the release and standardization of PrimeRail in the physical implementation kit for early analysis and signoff, Toshiba design teams see a significant productivity boost for their advanced and established node designs."
