Software spots clocking contention

SpyGlass-CDC allowed PLX to identify good synchronisations early in the design process.

PLX Technology 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 synchronisation", says 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 synchronising schemes like elastic buffers, FIFOs and asynchronous handshakes and we are pleased that the SpyGlass-CDC tool allowed us to identify good synchronisations 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", says 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 signoff".

"Partnering with industry leaders such as PLX gives Atrenta a keen insight into emerging design issues and helps us optimise the SpyGlass design platform for today's complex SoCs".
