Intersymbol Deploys Cadence Encounter Platform in Mixed-Signal Flow to Cut Design Cycles, Die Area
Virtuoso Digital Block Implementation Speeds Time to Market and Boosts Productivity

San Jose, Calif, 20 Dec 2005

Cadence Design Systems, Inc. (NASDAQ: CDNS) today announced that Intersymbol Communications, Inc, a supplier of Electronic Dispersion Compensation (EDC) Integrated Circuits for 10Gb/s optical networks, has successfully qualified the Cadence® Encounter® digital IC design platform in its mixed-signal design flow. The Cadence Encounter synthesis and place-and-route technology provide Intersymbol with reduced design cycles and significant savings in time and chip area.

"Using proven Cadence Encounter synthesis and place and route digital IC design technologies, will enable us to implement digital blocks in a much shorter time, with smaller die size, and at speeds approaching 700 MHz," said Sanjiv Chopra, Chief Operating Officer of Intersymbol Communications. "A complete mixed-signal solution tailored to our needs from a single vendor gives us a great advantage."

By using Encounter RTL Compiler XL synthesis and SoC Encounter L for placement and routing, Intersymbol achieved significant savings in digital block implementation. Both products are available with full features and capacity tailored for small digital block implementation as the Virtuoso Digital Implementation Option package. In addition to the Virtuoso custom design platform already in use, the Virtuoso Digital Implementation Option is an upgrade to Intersymbol’s design methodology. Based on detailed evaluation of the tool, Intersymbol has determined that the enhanced flow will result in higher design productivity and better quality of silicon (QoS),

"We are delighted that Intersymbol has deployed our Encounter platform in its mixed-signal flow," said Wei-Jin Dai, corporate vice president, R&D for Cadence. "Our technology is proven on large and complex digital designs, and we are pleased to offer the new Virtuoso Digital Implementation Option capabilities to address the growing need for digital-design capabilities in context of mixed-signal-design requirements driven through our Virtuoso platform."
