Tower Semiconductor Expands High-Voltage Technology Offering with Synopsys' Hercules PVS

New Rule Files Complement Tower's Release of High-Voltage Technology

MOUNTAIN VIEW, California and MIGDAL HAEMEK, Israel, December 12/ - Synopsys, Inc. (Nasdaq: SNPS), a world leader in semiconductor design software, and Tower Semiconductor Ltd. (Nasdaq: TSEM, TASE: TSEM), a pure-play independent specialty foundry, today announced that Synopsys' Hercules(TM) Physical Verification Suite (PVS) rule files are now available for Tower Semiconductor's release of 180-nanometer (nm) high-voltage technology. The availability of Hercules rule files for both design rule checking (DRC) and layout versus schematic (LVS) on this specialized process is the result of close cooperation between the two companies. Hercules rule files are also supported in Tower's standard logic technology processes.

"Tower's continued support of Hercules PVS for sign-off verification enables our customers to continue working in the Synopsys design environment for our specialized technology offering," said Yaakov Milstain, vice president and general manager for design services at Tower. "This joint endeavor is evidence of our strong relationship with Synopsys, one of the leading EDA providers."

The Hercules DRC rule file development, including support for specialized 180nm high-voltage devices, has been qualified for sign-off using a rigorous set of specialized test cases. Hercules LVS can also be used with Synopsys' Star-RCXT(TM) extraction solution to merge highly accurate parasitic data with the schematic-level devices. This unique capability delivers greater simulation accuracy while allowing circuit designers to design and analyze circuits at a familiar level of detail.

"The availability of Hercules PVS rule files for Tower's high-voltage technology demonstrates the broadening foundry support for Hercules PVS on specialized processes," said Anantha Sethuraman, vice president of marketing, Design for Manufacturing, at Synopsys. "Qualification by foundries such as Tower Semiconductor enables our mutual customers to benefit from higher DRC performance and a proven transistor flow."
