Entropic Communications Tapes Out Home Networking Device Using New Zroute Technology in Synopsys IC Compiler
Zroute Delivers Superior Quality of Results; Speeds Turnaround Time for Complex Home Networking Chip

MOUNTAIN VIEW, Calif., Sept. 15 /PRNewswire-FirstCall/ -- Synopsys, Inc. (NASDAQ: SNPS), a world leader in software and IP for semiconductor design and manufacturing, today announced that Entropic Communications, Inc. (NASDAQ: ENTR), a leading provider of silicon solutions to enable connected home entertainment, has successfully taped out its latest home networking chip using Zroute, Synopsys' new routing technology in IC Compiler. Zroute's unique architecture with state-of-the-art routing algorithms and native multi-threading support enabled Entropic to improve routing runtimes while still delivering high quality of results in timing, area and manufacturability. Compared to traditional routers, Zroute delivered higher quality of results, a zero-DRC (design rule check) layout with fewer wires and total vias, improved redundant via rate for better manufacturability and a significantly smaller die size.

"As a pioneer in connected home entertainment technologies, Entropic is always looking to take advantage of the latest advances in design tools," said Bill Lind, director of Engineering at Entropic. "As a Zroute early adopter, we saw significant improvements in runtime and manufacturability, particularly in via optimization. Based on these results, we decided to deploy Zroute for the tapeout of our latest home networking chip. Zroute was a key factor in further reducing the die size while still meeting timing and manufacturability goals."

Zroute was architected from the ground up to take advantage of best-in-class routing technologies and meet the demands of companies like Entropic that are developing complex, high-performance chips. Utilizing concurrent design-for-manufacturability (DFM) optimization techniques, including soft rules, via redundancy, and wire spreading and widening, Zroute makes an efficient trade-off between manufacturability and the traditional design goals of timing, area, power and signal integrity. In addition, Zroute's native multi-threading support takes advantage of the latest multi-core microprocessor architectures to deliver near-linear scalability of runtimes as the number of threads increases.

"Synopsys continues to invest in new technologies to meet customers' evolving needs," said Antun Domic, senior vice president and general manager of Synopsys' Implementation Group. "Zroute technology in IC Compiler is already driving customer success, and Entropic's tapeout is an excellent example of the differentiated performance and productivity enabled by the innovative Zroute architecture."

Zroute was announced in May 2008 and is targeted for general production availability as a standard feature in the September 2008 release of IC Compiler.

About Entropic Communications

Entropic Communications, Inc. is a leading fabless semiconductor company that designs, develops and markets systems solutions to enable connected home entertainment. The company's technologies significantly change the way high-definition television-quality video and other multimedia content such as movies, music, games and photos are brought into and delivered throughout the home.

About IC Compiler

IC Compiler provides hand-craft-quality macro placement, intelligent power network support, and MinChip technology for automatic die-size reduction, all on a single timer foundation that enables faster time to closure with higher quality of results (QoR). For complex designs, a concurrent flow that seamlessly blends planning and implementation tasks and offers an integrated environment with a single timer and high correlation with sign-off is critical. Concurrent planning and implementation replaces the traditional "plan-then-implement" methodology, resulting in faster time to tapeout and reduced design cost.
