P.A. Semi™ Achieves 1066 Mbps DDR2 Performance using SiSoft's Quantum-SI™

SANTA CLARA, Calif, and MAYNARD, Mass. - June 11, 2007 - P.A. Semi™ and Signal Integrity Software, Inc. (SiSoft™) together announced today that P.A. Semi has succeeded in achieving 1066 Mbps DDR2 performance on boards using its PWRficient™ processors through the use of SiSoft's Quantum-SI™ high-speed design analysis tool. P.A. Semi's family of PWRficient processors supports a variety of DDR2 memory configurations including memory down and multi-slot/multi-rank unbuffered and registered DIMMs.
 
"Using Quantum-SI we were able to quickly evaluate the impact of different design implementations and optimize our design," said Mark Hayter, P.A. Semi's chief system architect. "We correlated simulation results to lab measurements and determined that Quantum-SI accurately predicted the system level signal integrity and timing margins allowing us to maximize DDR2 operating speed. We have successfully run the memory system at 533MHz clock / 1066 Mbps data in our lab, and are prepared for when the DDR2-1066 devices are readily available and are standardized by JEDEC".

Quantum-SI accelerates design of high-speed interfaces by integrating timing and signal integrity analysis. Designers are able to use Quantum-SI to define components and routing strategies for different net classes in a high-speed interface. Quantum-SI then performs automated signal integrity analysis and combines the results with interface timing to determine signal integrity and timing margins. This allows designers to quickly evaluate different design tradeoffs and determine their impact on interface timing margins, instead of running multiple analysis tools and manually integrating results. SiSoft offers Quantum-SI design kits for popular interface standards like DDR2 that maximize designer productivity by further reducing the time needed to setup and perform design analysis.

"We think Quantum-SI and Quantum-SI design kits are an ideal fit for P.A. Semi and its customers," noted Barry Katz, SiSoft's president and CTO. "The high-performance embedded computing market demands rapid, cost-effective design. Instead of issuing 'one size fits all' layout rules for complex interfaces such as DDR2, P.A. Semi is enabling its customers to analyze and optimize designs based on their individual requirements for PCB area, layer count, manufacturing cost and performance. This allows P.A. Semi's customers to deploy PWRficient processors in a more cost-effective manner while still having high confidence in the reliability of the finished product."
