Atmel Tapes Out First Single-Chip DVD/CD SoC with Cadence Encounter Test

11/8/2005 - Cadence Design Systems, Inc. (NASDAQ: CDNS) announced that its new Cadence® Encounter® Test Architect technology has helped Atmel Corp. successfully tape out Atmel's first single-chip DVD/CD system-on-chip (SoC). With Encounter Test, Atmel's geographically distributed design team was able to fast track its project. This helped Atmel complete test insertion and automatic test pattern generation (ATPG) on time to achieve high-quality, first-pass manufacturing success.

Atmel's recently announced AT78C4050 is a SoC focused on driving down cost and complexity for next-generation, high-performance optical disc-drive designs. With this product, designers can, for the first time, use a single-chip controller that provides all analogue and digital functions for red and blue laser DVD and CD from servo system to ATAPI interface. Its integrated partial response, maximum likelihood (PRML) read channel technology provides higher speed, higher density and improved performance over any currently available products.

"We used a globally distributed design team for this complex, first-in-class product," said Mehdi Bathaee, Atmel's Network Storage Business Unit general manager. "Inserting the test and generating patterns in time for tapeout was key to our project's success. With Encounter Test, and the Cadence team's support, we achieved our time-to-tapeout and exceeded test coverage objectives."

"Atmel's experience is an example of how Encounter Test Architect's unique compiler-based methodology inserts all required test structures with its automatic test infrastructure compilation and verification methodology—all from a single specification," said Sanjiv Taneja, vice president of R&D for Encounter Test at Cadence. "We are proud to have contributed to Atmel's significant achievement with this design."
