San Jose, Calif., April 14, 2008- Atrenta Inc., the leading provider of Early Design Closure® solutions to radically improve design efficiency throughout the IC design flow, today announced that PLX Technology, the world’s leading supplier of PCI Express® (PCIe®) input/output (I/O) interconnect silicon, has adopted Atrenta's SpyGlass-CDC product to sign-off clock domain crossings (CDC) on PCIe Gen 2 switches at RTL.

"Our complex designs contain numerous asynchronous clock domains, necessitating comprehensive CDC verification for metastability, reconvergence and reset synchronization," said Vijay Meduri, director of design engineering at PLX.  "We used Atrenta’s SpyGlass-CDC tool to sign-off on the complex PCIe Gen 2 designs at RTL.  These designs contain advanced clock synchronizing schemes like elastic buffers, FIFOs and asynchronous handshakes and we are pleased that the SpyGlass-CDC tool allowed us to identify good synchronizations early in the design process - at RTL."

"Identifying and fixing bugs due to asynchronous clock domain crossings is becoming the number one priority for our customers, as traditional static timing analysis and functional verification tools do not exhaustively catch these chip killers," said Mike Gianfagna, vice president of marketing at Atrenta.  "We are delighted that PLX has chosen SpyGlass as the best-of-breed technology for CDC verification and sign-off.  Partnering with industry leaders such as PLX gives Atrenta a keen insight into emerging design issues and helps us optimize the SpyGlass design platform for today’s complex SoCs."

About SpyGlass-CDC
The SpyGlass-CDC solution is the industry's most comprehensive, practical, and powerful CDC solution. SpyGlass-CDC automatically identifies and formally verifies all synchronization schemes. Two particularly troublesome CDC-related issues involve FIFO- and handshake-based synchronization mechanisms. Both can be difficult or impossible to accurately verify using simulation. And conventional static CDC analysis tools do too little and too much at the same time - simultaneously overlooking real design errors and over-reporting large numbers of false violations. As a result, the user is forced into an endless bug-hunting process which often discourages the designer and leaves real bugs undetected. SpyGlass-CDC enables designers to quickly and easily eliminate critical bugs up-front, trimming weeks or months of downstream verification and redesign effort.
