Synopsys' VCS Verilog Simulator Delivers Accurate Gate-level ASIC Simulation to Oki Semiconductor Customers

MOUNTAIN VIEW, Calif.----May 25, 2000-- Oki Semiconductor and Synopsys, Inc. (Nasdaq:SNPS), reported the adoption of VCS(TM) as the sign-off simulator for Oki's entire range of 0.35 and 0.25 micron ASICs.

Oki customers designing complex, multimillion-gate ASICs now can accurately simulate their designs at the gate-level using Synopsys' VCS version 5.1.

``We are seeing much better performance, accuracy and capacity with VCS on our system-on-a-chip designs,'' said Jamshed Qamar, vice president, engineering department, R&D division of Oki Semiconductor. ``Fast sign-off capability helps meet our customers' critical time to market requirements.''

``Synopsys is pleased with Oki's recommendation of VCS as a sign-off simulator,'' said Ghulam Nurie, vice president of marketing for Synopsys' verification technology group. ``Sign-off means 'quality' and 'confidence', providing a clean verification flow for our mutual customers designing complex, multimillion-gate ASICs.''

Oki's ASIC Products

Oki Semiconductor has a major presence in the ASIC market, with extensive research and development partnerships with leading tool vendors. Oki's family of very deep submicron ASICs meets the industry's need for high-performance, low-cost system-level solutions, fueling the transition to system-on-a-chip (SoC) designs. Oki's ASICs are developed using an innovative platform-based approach that enables higher levels of productivity, reduced cycle time, and lower development risk through the sharing and re-use of intellectual property blocks. Oki's innovative mPlat ASIC platform is the world's first true ARM-based SoC, enabling Oki's customers to develop custom ICs in less time than with conventional ASICs.
