Sequence Physical Studio Leads to NEC First-Silicon Success

5/5/2003 - In its first production use of Sequence Design's PhysicalStudio, NEC Electronics America, is reporting first-time silicon success in the design of a 1.6-million-gate SoC.

The majority of the design ran at 160MHz, including a timing-critical microprocessor block, while the rest of the design ran at 80MHz. Built using a mature 0.25-micron process technology, the design required NEC Electronics America to stretch the design methodology to meet the required microprocessor performance.

After achieving maximum results for processor speed using state-of-the-art physical synthesis, NEC Electronics America got additional added value using PhysicalStudio for post-route optimization, which allowed the design team to achieve even higher processor speeds.

"With PhysicalStudio, we were able to achieve 160MHz on a 0.25 micron SoC design," said Wolfgang Roethig, Ph.D., senior design engineering manager, Design Solution Center, NEC Electronics America, Inc. "By using PhysicalStudio to deploy cross-talk-conscious timing optimization on the timing-critical block, we could push the performance to meet the customer's expectations, and saved considerable time and expense by getting first-time silicon working at speed."

"PhysicalStudio customers consistently find that this tool provides accuracy and performance benefits that simply cannot be matched by standard flows," according to Dr. Susheel Chandra, Sequence senior vice president of R&D and product marketing. "PhysicalStudio has the unique advantage of 'knowing' what the new routing will look like, even as it fixes crosstalk errors."

About PhysicalStudio
PhysicalStudio is an electrical design closure solution that resolves timing, signal integrity, voltage drop, and power issues concurrently in a single engine. It is fully interoperable with industry-standard routing tools, permitting existing physical design flows to reach fast, predictable design closure in silicon geometries below 90 nanometers.

PhysicalStudio's feature set includes the following:
