FOR IMMEDIATE RELEASE

XILINX DEPLOYS SYNOPSYS HSPICE FOR
BREAKTHROUGH 10 Gbps SERIAL I/O CIRCUIT SIMULATION

HSPICE Delivers S-Parameter Analysis for Complex High-Frequency Designs

SAN JOSE, Calif., May 6, 2003 - Synopsys, Inc. (Nasdaq:SNPS), the world leader in integrated circuit (IC) design software, today announced that Xilinx, Inc. (Nasdaq:XLNX) has validated HSPICE® for use in its 10 Gbps RocketIO™ X Multi-Gigabit serial I/O design kit. Recognized as the de facto industry-standard golden-accuracy circuit simulator, HSPICE - a component of the analog mixed-signal (AMS) solution within Synopsys' Verification Platform - now supports directly measured scattering-parameters (S-parameters) analysis, which is critical to modeling and simulation of system-level signal integrity effects in high-frequency designs.

The RocketIO design kit supports the new Virtex-II Pro™ X FPGA architecture with integrated 10 Gbps RocketIO X transceivers, which was announced by Xilinx today. Customers under the Xilinx early access program are currently designing with the RocketIO X Multi-Gigabit serial I/O design kit using HSPICE.

"We have used HSPICE as one of our prime circuit simulators for years. The ability to import S-parameters into HSPICE simulation enables system designers to easily extract S-parameter models using a network analyzer and to use them for high-frequency system simulations," said Scott Irwin, engineering director of the Communications Technology Division at Xilinx. "HSPICE, with S-parameter analysis, is the first simulator used in our RocketIO X design kit to verify data rates over 10 Gbps, allowing our customers to accurately design and simulate their state-of-the-art high-frequency serial I/O interfaces."

HSPICE has long been recognized as the industry standard for highly accurate circuit simulation of integrated circuit designs. Its advanced algorithms provide comprehensive simulation and analysis capabilities with high accuracy and reliable convergence characteristics. HSPICE features the most extensive support of semiconductor device models, which are certified by all major semiconductor foundries.

"The importance of HSPICE within advanced circuit simulation flows is increasing as process geometries continue to shrink," said Antun Domic, senior vice president and general manager of Synopsys' Nanometer Analysis and Test business unit. "Working with leading-edge devices from Xilinx® enables us to continuously improve HSPICE, a cornerstone of Synopsys' mixed-signal design and verification solution."
