MOUNTAIN VIEW, Calif., and MIGDAL HAEMEK, Israel, November 17, 2010— Synopsys, Inc. (Nasdaq: SNPS), a world leader in software and IP for semiconductor design, verification and manufacturing, and TowerJazz (NASDAQ: TSEM, TASE: TSEM), the global specialty foundry leader, today announced that they have collaborated to qualify Synopsys’ custom design solution with TowerJazz’s 180-nanometer (nm) power management (PM) interoperable process design kit (iPDK) and analog/mixed-signal (AMS) PM reference flow. The qualified solution from Synopsys includes the Galaxy Custom Designer® implementation, HSPICE® circuit simulation, CustomSim™ FastSPICE simulation, and StarRC™ parasitic extraction tools. The TowerJazz AMS PM Reference Flow with the 180-nm iPDK provides mutual customers with a comprehensive, productive and open custom design solution.

“TowerJazz and Synopsys have been working together to create and promote iPDKs as an open standard for the custom design community so engineering teams only need to develop a single PDK for each process node, reducing development costs and design cycle times,” said Ori Galzur, vice president of design center and design enablement at TowerJazz. “Synopsys’ world-class team provided TowerJazz with on-site iPDK training as well as expertise in iPDK interoperability and validation methodologies. This collaboration further expands our relationship to offer a comprehensive, open analog/mixed-signal design solution.”

The TowerJazz AMS PM Reference Flow includes a reference design that is based on the TowerJazz 180-nm iPDK and a set of documentation that covers the overall flow as well as the detailed reference flow steps. Mutual customers can quickly learn the complete power management design flow including schematic capture, simulation, layout, physical verification and extraction. In addition, important productivity features are highlighted to help designers complete their designs on time and help ensure first pass silicon success.

“We welcome TowerJazz’s leadership in adopting the iPDK standard and applying it to their advanced power management process and reference flow,” said Bijan Kiani, vice president of product marketing at Synopsys. “Through this partnership, we can ensure that our mutual customers achieve fast turnaround time from design specification to production.”

About TowerJazz 180-nm Power Management Process and Features

TowerJazz’s 180-nm power management process is a cost-effective solution which offers modular add-ons such as a unique zero-mask-adder, multi-programmable, non-volatile memory (NVM) solution, thick copper-top metallization for high current drive, and an optional 1.8-volt (V) gate for heavy digital power management integrated circuits (ICs). In addition, it offers scalable LDMOS devices that provide excellent area optimization of the power devices for up to 60 volts, all with very low mask count.
