Xilinx Press Release #02123
FOR IMMEDIATE RELEASE

SAN JOSE, Calif., July 30, 2002 -Xilinx, Inc., (NASDAQ:XLNX) today announced that IneoQuest Technologies, an emerging leader in designing and building the next generation of network traffic generation and performance analysis systems, developed its leading-edge Singulus™ G1 family of Gigabit Ethernet network systems using Xilinx® Virtex-II™ series Platform FPGAs. IneoQuest attributes its six-month development time to using Xilinx reprogrammable FPGAs in lieu of a traditional ASIC. IneoQuest is among a growing number of networking companies to gain a competitive advantage through its use of Xilinx programmable logic solutions.

"The challenge was to build a cutting edge platform that is not only expandable, but one third the cost of any comparable solution," said Marc Todd, president and chief executive officer at IneoQuest Technologies. "The reconfigurable nature of Virtex-II Platform FPGAs allows us to upgrade the system with new features using the same hardware base."

In addition to using Virtex-II Series FPGAs, IneoQuest developed the Singulus system using Xilinx™ ISE 4.2i logic design software, an IBM PowerPC 405 processor, and Wind River Systems development tools. This combination allowed IneoQuest engineers to partition the development and work in parallel, then integrate the hardware, software, and FPGA logic quickly and efficiently. For more information about how this was accomplished visit www.ineoquest.com/SG1CSv3_XilinxWebcast.pdf.

"Xilinx Virtex-II series FPGAs and ISE 4.2i software tools provide our customers with the industry's highest performance and highest density platform for new product development," said Babak Hedayati, senior director of Product Solutions Marketing at Xilinx. "We partnered with best in class companies such as IBM and Wind River Systems to ensure standard, flexible and scalable design methodologies for our customers."
