TranSwitch Renews Rio Design Automation's RioMagic License; Package-Aware Chip Design Software Holds Promise for Low-Cost, Highly Optimized Silicon Parts, Says TranSwitch.

SANTA CLARA, Calif. -- Rio Design Automation Inc. today said that TranSwitch(R) Corporation (NASDAQ: TXCC), a leading provider of high-speed semiconductor solutions for voice, data and video communications, has renewed its multi-year, multi-site RioMagic license.

RioMagic is package-aware chip design and optimization software that bridges the gap between the design of high-performance integrated circuits (ICs), their packages and the rest of the system design. TranSwitch is in the process of integrating RioMagic into its design flow and will use it on the design of its future communication products.

"RioMagic allows us to do the proper planning to reduce risk on final layout," says Ed Linke, director of Assembly and Packaging at TranSwitch. "This saves both time and money to get the product to release. RioMagic allows us to reduce the change and 'what if' time needed on today's most complex designs."

RioMagic considers package escape, routability and parasitics, and enables simultaneous tradeoffs between chip and package design. Through its interconnect synthesis, it analyzes a wide range of variables to converge on a final I/O plan. With its embedded chip/package extraction, estimation and simulation capabilities for signal and power integrity, the impact on electrical performance is understood and addressed before final implementation.

Remarks Kaushik Sheth, Rio Design Automation's chief executive officer (CEO): "TranSwitch has been an important partner for us. They have used RioMagic on a number of designs and have given us valuable feedback."
