David Chyan of Cadence Receives Gene Marsh Award for Technical Innovation at PCB Design Conference East

SAN JOSE, Calif. — October 27, 1999 — Cadence Design Systems, Inc. (NYSE: CDN), the world's leading provider of electronic design products and services, today announced that David Chyan, the company's vice president of circuit connectivity technology, was awarded the Gene Marsh Award for Technical Innovation on October 14 at the PCB Design Conference East in Marlborough, Massachusetts. The award was shared with Chyan's former partner, John Cooper, and honors the work that both gentlemen did at Cooper & Chyan Technology (CCT) to create the next generation routing technology, now known as the Cadence SPECCTRA® autorouter.

The Gene Marsh Award for Technical Innovation is sponsored by Printed Circuit Design magazine and is presented every year at the PCB Design Conference East to an individual (or individuals) who has made a significant contribution to the world of systems-level design. This year's presentation was made by Printed Circuit Design's publisher, Pete Waddell. Past recipients of the award include Gene Marsh, founder of PADS Software, and Richard Nedbal, founder of PCAD and Advanced CAM Technologies, Inc.

Chyan reflected on the award, "First, I'd like to thank God, and second, I'd like to thank John Cooper for the opportunity to work with him on CCT for nine years." As one of Cadence's most senior technologists and innovators, Chyan is a Cadence Fellow. He holds an MSCS from the University of Southern California and a BSEE from National Taiwan University. He co-founded CCT in 1989 with John Cooper after leaving Mentor Graphics Corporation where he worked on the router in the printed-circuit board (PCB) division. Prior to Mentor Graphics, Chyan was with Xerox in the PCB CAD group.

At the Conference, Cooper accepted the award on behalf of Chyan and offered insight into his former partner, "David is a man of few words and a lot of great work."

The SPECCTRA autorouter was constructed on a new shape-based technology conceived by Cooper and Chyan, and quickly became the industry standard for routing high-speed PCBs. In 1997, Cadence finalized its acquisition of CCT and Chyan joined the company to continue development of SPECCTRA. Prior to SPECCTRA, autorouters were grid-based but this technology became too limited for high-speed, surface mount boards. The SPECCTRA shape-based autorouter continues to be at the forefront of routing technology because it can support advances in high-speed interconnect and PCB packaging.
