Virtual Silicon PLL Validated as Ready for IBM Technology

SUNNYVALE, Calif. - July 7, 2003 - Virtual Silicon Technology Inc., a leader in semiconductor intellectual property (SIP), today announced the introduction of its PLL compiler validated as "Ready for IBM Technology" for IBM's 130-nm foundry process. IBM's foundry customers will be able to license high-performance PLL instances constructed by Virtual Silicon's world class PLL compiler technology.

"Virtual Silicon is a recognized leader in PLL technology," said Mike Concannon, vice president of foundry and manufacturing services at IBM Microelectronics. "IBM is committed to expanding the options for our foundry customers through support of a wide array of key IP."

"Offering our products on IBM foundry processes opens a new level of opportunity for Virtual Silicon," said Barry Hoberman, CEO for Virtual Silicon. "IBM's focus on leading-edge process technology matches well with Virtual Silicon's leadership in high-performance IP."

The "Ready for IBM Technology" mark identifies solutions that have been tested and validated for compatibility with IBM Microelectronics products by the solution developers and assures that these solutions are compatible with IBM Microelectronics products. IBM Business Partners who are validated will be marketed visibly in the Global Solutions Directory http://www.software.ibm.com/solutions/isv - making it easier for customers to find solutions quickly and easily with the designation "Ready for IBM Technology."

The PLL compiler is an addition to the company's existing standard cell and interface IP for IBM 130-nm technology. Virtual Silicon's high-performance standard-cell library is a fundamental element of leading-edge computing and communication system-on-chip (SoC) designs. The offering includes basic I/Os that are flip-chip and area-array compatible. Virtual Silicon's application specific I/O products are targeted at providing physical layer solutions for next generation chip-to-chip communications. Products include HSTL, SSTL2, LVDS, PCI 2.2 and PCI-X. The high-speed interface products are coupled with highly accurate DLLs to provide customers with complete QDR (HSTL) and DDR (SSTL2) solutions.

Virtual Silicon's product offering for IBM's 130-nm foundry process is available for license now, and has already been used by three customers for the development of SoC designs. Virtual Silicon's IP has been designed bottom-up specifically for IBM's 130-nm foundry process and its customers who require the utmost in performance. The IBM 8SF PLL Compiler was developed in conjunction with Analog Bits, Inc.
