Synopsys' Hi-Speed USB OTG IP is First and Only Complete IP Solution To Earn Hi-Speed USB OTG Certification

Certified digital and PHY IP gives designers the flexibility to choose from 130nm or 90nm processes

MOUNTAIN VIEW, Calif. ¨C May 12, 2005 - Synopsys, Inc. (Nasdaq:SNPS), a world leader in semiconductor design software, today announced that its DesignWare® Universal Serial Bus On-The-Go (USB OTG) digital core plus three physical interfaces (PHYs) intellectual property (IP) is the first and only complete OTG IP solution to be certified by the USB Implementers Forum (USB-IF). The certification helps ensure DesignWare users of interoperability with Hi-Speed USB PCs and Hi-Speed USB OTG products.

"USB is the most successful PC connectivity standard of all time and it has successfully migrated into CE and Mobile devices. We welcome Synopsys' work to further the standard's acceptance in the marketplace," said Jeff Ravencraft, chairman and president of the USB Implementers Forum (USB-IF). "As an active member of the USB-IF Synopsys continues to help ensure high-quality USB specifications."

"We looked to Synopsys for the complete, high-quality, Hi-Speed USB OTG solution that we needed to quickly and reliably integrate into our portable audio platform," said Mario Manninger, director of engineering, Communications Business Unit of austriamicrosystems. "Synopsys' rigorous approach to quality and risk reduction has enabled us to make Hi-Speed USB connectivity a differentiating feature of our products."

"Certification of our IP, both digital and physical layers, gives our customers and their users' greater assurance of proven USB functionality and interoperability," said Eric Huang, product marketing manager for DesignWare USB IP at Synopsys. "Designers can now select from more semiconductor processes to align with targeted silicon costs. They can use our certified digital core with one of our three certified PHYs ©¤ two in 130nm and one in 90nm processes. Synopsys continues to lead the way in risk reduction by participating at the first Hi-Speed USB OTG plugfest held by the USB Implementers Forum, and passing all the tests with not just one, but three PHYs." Huang also serves as chair of the USB On-The-Go Working Group.
