IBM, Chartered Select Synopsys' Hi-Speed USB 2.0 and OTG PHYs for Their 90-nm Process Platform

Synopsys DesignWare® PHY IP Enables Reliable USB Connectivity for IBM and Chartered foundry customers

MOUNTAIN VIEW, Calif. – May 25, 2005 - Synopsys, Inc. (Nasdaq:SNPS), a world leader in semiconductor design software, today announced that IBM and Chartered Semiconductor Manufacturing have chosen Synopsys' DesignWare® Hi-Speed USB 2.0 and USB OTG physical layer (PHY) mixed-signal intellectual property (IP) for their 90-nanometer (nm) common process. With the USB 2.0 design kits, designers can take full advantage of the proven Synopsys USB IP solution which lowers their design and integration risks and speeds time to production volume.

IBM and Chartered collaborated with Synopsys to ensure that the DesignWare USB IP solution, which includes mixed-signal PHYs, digital controller cores and verification IP, is optimized for the companies' 90-nm common process platform. Proven in 180-, 130- and 90-nm, the DesignWare USB 2.0 and OTG PHYs passed through rigorous electrical and interoperability tests by the USB Implementers Forum and have been used by designers in a number of market-leading high-volume products. DesignWare USB PHY IP design kits include simulation models, documentation and GDSII layout information, which minimizes integration and verification time designers spend adding USB connectivity to their system-on-chip (SoC) designs.

"Making Synopsys' USB 2.0 IP available to designers using the IBM-Chartered common process platform is an important part of our open platform strategy," said Walt Lange, field executive, Systems Solutions at IBM. "Their ability to provide a competitive solution including verification IP within the design flow is a key enabler for our customers using USB 2.0 interfaces."

"Synopsys is one of the leading providers of PHY IP and we are pleased to be working with Synopsys on the 90-nm common process platform," said Kevin Meyer, vice president of Worldwide Marketing at Chartered. "The competitive die size and power consumption of the Synopsys DesignWare PHYs, combined with the complete USB digital controller IP offering, enable designers to quickly add cost-effective USB connectivity in applications like high performance game machines, office peripherals, and battery powered portable audio and video devices."

"IBM and Chartered are enabling customers to realize the benefits of their 90-nm common process platform with Hi-Speed USB connectivity," said Guri Stark, vice president of Marketing in Synopsys' Solutions Group. "Our collaboration with these leading companies to provide key IP design components will enable SoC designers to quickly achieve cost-effective volume production."

Availability
The USB 2.0 design kits for the Chartered and IBM 90-nm common process platform are expected to be available in Q3 of 2005. DesignWare controllers and PHY IP for Hi-Speed USB OTG, Hi-Speed USB Host and Hi-Speed USB Devices are currently available. DesignWare USB verification IP is currently available to DesignWare Library and DesignWare Verification Library licensees at no additional charge.
