Sunplus Picks Celestry for High Performance Clock Tree Synthesis

9/6/2002 - Celestry Design Technologies, the leading provider of Silicon Accurate Sign-offTM technology for the semiconductor and electronics industry, announced that Sunplus Technology Company Ltd. (Hsin-Chu, Taiwan), a fast-growing fabless designer of multi media, LCD controller, micro-controller and other ICs, has adopted its ClockWiseTM for its submicron design flows.

Celestry’s ClockWise helps customers achieve better silicon performance in hours rather than weeks with its useful skew clock tree synthesis technology. With it, SoC designers can achieve better performance and faster timing closure when using advanced semiconductor processes.

"With ClockWise, we consistently see at least a 2x runtime performance improvement and remarkable skew improvement over our previous clock tree synthesis tool. ClockWise’s plug-and-play technology, which is more flexible for handling the complex clocking schemes in our designs, fits well in our physical synthesis flow." remarked Mr. Ching-Hsiang Yang, Manager, CAD Dept., Sunplus Technology.

"We are very happy to see ClockWise endorsed by a fast growing company like Sunplus and having ClockWise widely adopted throughout Sunplus’ advanced design flow methodology," remarked Mr. Bob Xu, VP of International Sales and Operations of Celestry.

Celestry’s ClockWise provides traditional zero skew as well as useful skew clock tree synthesis, and works seamlessly with the industry’s standard place and route tools. With its useful skew methodology, it improves the timing on critical paths, and helps designs reach timing closure faster. Additionally, the silicon proven technology can reduce peak power and noise from simultaneous signal switching for longer battery life and better circuit reliability.
