Nascentric Unveils OmegaSim -- Its Next Generation Mixed Analog/Digital Fast-SPICE Simulator

YOKOHAMA, Japan—(BUSINESS WIRE)—January 23, 2008— Nascentric, Inc., an Electronic Design Automation (EDA) company focused on providing the fastest, highest capacity, and most accurate Fast-SPICE simulation and analysis tools, announced here today the availability of its newest, ground-breaking simulator, OmegaSim(TM). OmegaSim combines the best of Fast-SPICE and traditional SPICE simulators for high-speed verification of mixed analog/digital designs.

Fast-SPICE tools are typically used to achieve more speed and capacity when verifying large memory and custom digital designs. The sensitive analog circuitry contained in mixed-signal designs, however, often requires the use of slower, traditional SPICE algorithms for additional accuracy.

OmegaSim is the industry's first multi-threaded, mixed analog/digital Fast-SPICE simulator to handle designs in excess of tens of millions of transistors, parasitic capacitors, and resistors. It offers a 10X performance improvement over competing Fast-SPICE tools, plus it has comparable accuracy to Berkeley SPICE or its commercial variant SPICE simulator for mixed analog/digital verification.

"OmegaSim fills a well-known void in the SPICE and the Fast-SPICE markets. In the past, designers of large mixed-signal designs had to choose between the performance and capacity of Fast-SPICE or the accuracy of traditional SPICE," said Rahm Shastry, President and CEO of Nascentric. "Now, OmegaSim provides the best of both worlds - industry-leading Fast-SPICE performance with traditional SPICE accuracy in a seamless, multi-threaded package that meets the performance, capacity, and accuracy requirements of sub-65 nanometer design."

"After applying and extending several of our key patents, we have obtained results within 1% of SPICE in recent customer benchmarks," said Dr. John Croix, Chief Technology Officer and founder of Nascentric. "We've developed algorithms that switch between Fast-SPICE and traditional SPICE-level accuracy, depending on performance and accuracy requirements. We've also enhanced our multi-threading technology specifically for mixed-signal designs."

Pricing & Availability

North American pricing for OmegaSim is $1,200 per thread per month (thread-month) or $12,000 per thread per year (thread-year), and the mixed analog/digital option is an additional $500 per thread-month or $5,000 per thread-year. The minimum subscription commitment is 10 thread-months.

The scheduled beta release is scheduled for February 18, 2008 and the first customer shipment is scheduled for June 9, 2008.
