PLX TECHNOLOGY, JASPER DESIGN AUTOMATION JOIN FORCES TO BRING FORMAL VERIFICATION TO PLX PCI EXPRESS SILICON

Sunnyvale and Mountain View, Calif. - June 30, 2003 - PLX Technology (NASDAQ: PLXT), the leading supplier of standard I/O interconnect silicon to the communications, server, storage and embedded-control industries, and Jasper Design Automation today announced the two companies have joined forces to bring formal verification to PLX® chips based on PCI Express™ technology, via the JasperGold® Verification System formal verification tool. PLX conducted an extensive evaluation of JasperGold Verification System - a complete, user-friendly formal verification solution that can detect 100 percent of the design bugs in most complex electronic design blocks - for PLX's recently announced line of PCI Express-based chips. The two companies also announced that PLX has adopted JasperGold Verification System's pre-qualified PCI Express Proof Kits to support PLX's next-generation designs based upon PCI Express.

"PLX Technology has developed a broad array of PCI interconnect silicon products used throughout a multitude of industries and is today also developing PCI Express switch and bridge products," said Mark Lipford, vice president of engineering at PLX. "Our customers demand rock-solid operation, 100 percent compliance with industry specifications and interoperability with a wide variety of other devices. PLX has successfully applied Jasper Design Automation's JasperGold Verification System verification tool on multiple development projects, helping PLX meet these high expectations."
"We're seeing a number of our customers leverage the measurable proof-of-quality afforded by JasperGold Verification System for a strategic marketing advantage," said Kathryn Kranen, CEO for Jasper Design Automation. "We are delighted that PLX Technology will be able to show their customers that they have verified 100 percent compliance with interface standards and spec-level requirements on which they used JasperGold Verification System."

The pioneering use of JasperGold Verification System was driven by PLX Technology's commitment to having verification tools and methodologies that deliver first-time design success. With simulation alone, complex corner-case bugs can easily remain undetected until after the availability of silicon prototypes. Not only may it then require several weeks of failure analysis to detect these bugs, but the subsequent silicon re-spin adds to costs, as well as threatening time to market. Consequently, PLX evaluated formal verification tools from six different electronic design automation (EDA) vendors in a rigorous, three-month test.

PLX's PCI-based silicon products have achieved significant penetration into the embedded market, providing essential I/O for a wide array of applications across multiple industries. Through its recently announced PCI Express-compliant, high-speed bridging and switching chips, PLX is paving the way for migration to the increasingly popular next-generation architecture standard. The architecture allows system manufacturers to realize faster time-to-market.

PLX has been developing I/O interconnect devices since 1986. Jasper Design Automation has been developing true formal functional verification solutions since 1999.
