QualCore Logic Joins Tower Semiconductor's Authorized Design Center (TADC) Program

Full Complement of Proven, High-Quality Design Services Helped QualCore Logic Pass Rigorous Criteria

Sunnyvale, Calif., November 22, 2004 –– Tower Semiconductor Ltd. (Nasdaq: TSEM, TASE: TSEM) today named QualCore Logic Inc., an intellectual property (IP) and full-service, application specific integrated circuit (ASIC) realization company, a member of the Tower Authorized Design Center (TADC) program.

TADC program was created to help Tower’s customers accelerate the design-to-silicon process and enhance first-time silicon success.  It links Tower Semiconductor to leading integrated circuit (IC) design firms such as QualCore Logic, providing hardware designers with qualified support for the Tower Semiconductor fabrication flow.

QualCore Logic offers a full spectrum of design services, from register transfer level (RTL) development to fully verified GDSII, including comprehensive analog and mixed-signal development capabilities.  In addition to these services, customers can also take advantage of QualCore Logic’s broad portfolio of analog and digital intellectual property (IP) blocks that target Tower Semiconductor’s foundry processes.

“Tower’s criteria for this program is rigorous,” said Doron Simon, President of Tower Semiconductor USA.  “QualCore Logic needed to demonstrate its ability to provide proven, high-quality services and create designs that comply with our design and verification rules, and they have done it in a clear and decisive manner.  QualCore Logic complements Tower’s value added foundry services and enables us expand our analog and mixed signal design support locally to our Silicon Valley customers base.”

Adds Mahendra Jain, president of QualCore Logic:  “Qualifying for the Tower   Authorized Design Center program reinforces our commitment to delivering quality design services and Intellectual Properties (IP).  Tower’s customers can confidently engage with QualCore Logic and be assured of first-pass silicon success.”
