TowerJazz Announces Participation at EDSFair in Japan to Further Awareness for

its World-Class Design Enablement Technology

Provides several demonstrations with leading EDA companies

NISHIWAKI, Japan, November 13, 2012 – TowerJazz , the global specialty foundry leader, today announced it will participate at the Electronic Design and Solution (EDS) Fair in Yokohoma, Japan on November 14-16, 2012 to further its relationships with its EDA partners in Japan and gain more exposure with Japanese fabless companies and IDMs for the local availability of its pure play foundry offerings and design enablement innovation. Last year, TowerJazz introduced its world-class design enablement technology to the Japanese market, including its 700V power management process design kit (PDK) addressing the fast-growth, emerging LED commercial lighting market. At the EDSFair, TowerJazz will provide seminars and demonstrations with its EDA partners to offer attendees hands-on experience with its PDKs and a chance to meet the TowerJazz Japan design enablement team in person (booth D-33).

“At the EDS Fair, this year we have a dedicated booth and are planning a number of demos with our EDA partners to showcase our design enablement capabilities,” said Ori Galzur, Vice President of Design Center and PDK Development at TowerJazz. “This is our second time at the EDSFair since our acquisition of Micron’s Japan fab in Nishiwaki last year. The EDSFair is an important conference in Japan and we are excited to build further awareness for our local foundry offerings and increase visibility for TowerJazz in the APAC region.”

TowerJazz offers customers novel design enablement tools that leverage the tight interaction between EDA, models and process technology to improve time to market and yield of highly integrated analog products. TowerJazz offers a complete design enablement platform that complements its sophisticated technology and enables a quick and accurate design cycle to enable first-time working silicon and fast time-to-market. This platform includes silicon verified and highly scalable device models and robust physical design tools for up front design optimization. TowerJazz’s powerful and efficient tools enable unprecedented accuracy in device models and its unparalleled customer support at every stage of the design flow ensures confidence in designs at near zero risk.

At the EDSFair, TowerJazz will provide four seminars; one which focuses on its design enablement capabilities and the others with partner companies: IPL, Mentor Graphics and Tanner EDA.
