NEWPORT BEACH, Calif., May 7, 2009 - Jazz Semiconductor,® Inc., a Tower Group Company (NASDAQ: TSEM, TASE: TSEM), and a leader in Analog-Intensive Mixed- Signal (AIMS) foundry solutions, today announced it will host a techtorial featuring the Cadence Design Systems Virtuoso® IC 6.1 custom design platform entitled, "Knowing Your Design is Right." The techtorial will be held on June 4, 2009 at Jazz headquarters in Newport Beach, CA and will be presented by Cadence® at multiple other venues throughout the United States over the next several months.

Custom design requires both flexibility and consistency in the design flow to address the broad array of challenges engineers address on a daily basis. The key challenge is being able to effectively and efficiently explore and validate a design as early as possible in the flow. The Cadence Virtuoso custom design platform improves efficiency by streamlining the common tasks involved in custom design, enabling IC designers to concentrate on the unique challenges of creation and implementation.

The Virtuoso techtorial will follow a keynote by Robert Milkovits, Director, Design Support at Jazz Semiconductor and is intended for analog/mixed-signal design managers and supporting CAD managers. The keynote will include a technical overview of how Virtuoso tools meet modern design challenges and tighter deadlines. A lab/workshop will be offered by Cadence, geared toward existing users of Virtuoso tools on the IC 5.1.41 release in both electrical and physical design. Attendees will also have the opportunity to test-drive the latest in the industry's leading solution for custom IC design.

"We continue to provide new solutions to speed time to market for AIMS products through design enablement technology such as the Virtuoso IC 6.1 platform for our 0.18um SiGe BiCMOS process," said Dr. Marco Racanelli, Senior VP and General Manager, RF and High Performance Analog Business Group, Jazz Semiconductor. "The partnerships we forge with leading EDA vendors such as Cadence, coupled with our silicon-accurate models and proprietary design tools, provide our customers a complete design environment with a track record of first-pass success for high-performance analog and RF products."

"Through Jazz's early adoption of the Virtuoso IC 6.1 platform, we have been able to provide our mutual customers with high-quality PDKs to achieve more predictable designs and decrease cycle times for their highly differentiated RF and analog-intensive mixed-signal AIMS IC designs," said Tom Beckley, corporate vice president at Cadence. "We look forward to sharing the advantages of the Virtuoso platform with many more mixed-signal designers and CAD managers at the upcoming techtorial hosted by Jazz."
