Synopsys' HSPICE High-Voltage MOS Transistor Model Adopted by UMC
New, Accurate Model Speeds Time to Results by 2X

Synopsys, Inc. (NASDAQ: SNPS), a world leader in semiconductor design software, today announced that UMC (NYSE: UMC), a leading semiconductor foundry, has adopted Synopsys' new high-voltage MOS (HVMOS) transistor model and is distributing model parameters to UMC customers who use the HSPICE® simulator. Synopsys' HVMOS model incorporates all the critical physical effects of various high-voltage transistor technologies that are in use today, thereby improving simulation accuracy and reducing the risk of chip re-spins. This new model will help UMC customers improve the quality of results and time to results for their design projects.

"UMC has verified Synopsys' HVMOS model for our high-voltage processes and is adopting it for our 0.25um and 0.18um HVMOS customers," said Dr. Jin Shyong Jan, director of device modeling at UMC. "We have found Synopsys' HVMOS model to be highly accurate when compared with other approaches. Since using the new model, we have seen significant improvement in turnaround time for model parameter extraction and validation."

UMC offers high voltage process technologies that are used to support applications including LCD and plasma display drivers, automotive electronics, computer periphery, small DC motor controls, DC-DC converters, power management and consumer electronic products.

"The HSPICE simulator has been widely accepted as the industry's 'gold standard' circuit simulator, especially in regards to its breadth and depth of model support," said Edmund Cheng, vice president of marketing, Silicon Engineering Group at Synopsys. "The superior accuracy and speed of parameter extraction that this new HVMOS model offers is the reason why we have seen increased adoption by major IDM and foundry customers since the model's introduction six months ago."


Synopsys' HVMOS transistor model is currently available in the HSPICE simulator, as well as in the Aurora™ model parameter extraction tool.
