Oki Standardizes on Synopsys' HSPICE High Voltage MOS Model
Synopsys, Inc. and Oki Electric Co., Ltd. announced that Oki has standardized on the new HSPICE® high voltage MOS (HVMOS) model for the design of Oki's LCD television (TV) driver system-on-chip (SoC). Oki achieved unparalleled accuracy using this HVMOS model with HSPICE technology, the "Gold Standard" in circuit simulation. This high correlation between device model and silicon enables Oki to accurately design complex, high-voltage drivers that deliver vivid, ultra high-resolution images for large-screen LCD TVs and other advanced integrated circuits in its telecommunications, automotive, computer and consumer product lines.
"We were able to obtain excellent accuracy, performance and convergence using Synopsys' HSPICE technology with the new HVMOS model and the Aurora model parameter extraction tool," said Ichiro Yamamoto, senior manager, Design System Department in the LSI Design Division of Oki Electric's Silicon Solutions Company. "Other commercial simulators with HVMOS models typically produced large variations of up to 30 percent when compared with measured data from silicon. This variability made it difficult to fit the model parameters within an acceptable accuracy range, causing several expensive and time-consuming chip re-spins. While correlating silicon within a few percent with the new HSPICE HVMOS model and the Aurora tool, Oki has reduced the model parameter extraction time from several days to two hours."
Oki has jointly validated the newly developed HVMOS model with Synopsys. The model incorporates all of the necessary and critical physical effects of various high voltage transistor technologies that are in use today. This HSPICE HVMOS model has been verified using several production circuits across a wide range of operating voltage, temperature and process technologies. In addition, this unique HVMOS technology greatly reduces the model parameter extraction and validation time from weeks to hours. Using this HVMOS model, Oki was able to realize an improvement in both the quality of results (QOR) and the time to results (TTR) for its design projects.
"Synopsys is committed to delivering technology and software products like the HSPICE simulator that address circuit simulation needs of the most advanced IC designs," said Edmund Cheng, vice president of Marketing, Silicon Engineering Group at Synopsys. "The new model is measurably more accurate than other commercially available models and greatly reduces Oki's design time for their high definition LCD TV drivers."
Availability
The HVMOS model will be available for general release in the HSPICE simulator in March 2005. The beta version is available for evaluation now. The HVMOS feature of the Aurora"T transistor model parameter extraction tool is also available for evaluation now. The HSPICE simulator is a part of Synopsys' Discovery"T AMS mixed-signal verification solution, which is based on the industry-leading VCS® simulator, NanoSim® simulator, and HSPICE simulator. These best-in-class production-proven simulators provide a unique combination of accuracy, performance and capacity with the flexibility of simulating design abstractions in any combination of Verilog, SPICE and Verilog-A.
