OEA Validated Legend's MSIM Circuit Simulator for Quality of Results in

Signal Integrity Analysis of High-Speed Interconnects

Morgan Hill and Santa Clara, California – May 11, 2004. OEA International, Inc. (OEA), the industry leader in 3D interconnect extraction, and Legend Design Technology, Inc. (Legend), the leading provider of semiconductor IP characterization and simulation software, today announced that OEA has entered partnership with Legend, and successfully qualified Legend's circuit simulator MSIM for interconnect modeling with inductances and signal integrity analysis.

"For today's high-speed circuit designs, signal integrity analysis and interconnect modeling using 3D extraction is definitely required," said Jerry Tallinger, Vice President of Marketing and Sales at OEA International, Inc. "I am pleased to see the high accuracy of the results from qualifying our interconnect modeling and signal integrity analysis tools with the MSIM circuit simulator.  The MSIM has been well proven in handling the RCLM (Resistors, Capacitors, Inductors, MOSFETs) models, especially in the cases of mutual inductances. Not only have we the superior accuracy, but also the productivity gains with the high simulation speed of MSIM. We certainly look forward to closer cooperation with Legend to ensure our customers receive the best tools with highest quality."

"Accurate signal integrity analysis and accurate interconnect modeling is the key for first-silicon-success in deep-submicron and nanometer design," said Dr. You-Pang Wei, President and Chief Executive Officer of Legend Design Technology. "I am glad that OEA has validated Legend's MSIM as a tool-of-choice for circuit simulation in signal integrity analysis.  With both Legend's MSIM and OEA's EDA tools, we believe customers will experience a high Quality of Results for on-chip and package interconnects."
