Synopsys Adds Noise Modeling Capabilities to Liberty Open Library Standard

10/15/2002 - Synopsys, the technology leader for complex integrated circuit (IC) design, announced that it has added noise modeling capabilities to its widely used LibertyTM open library standard. The new capabilities will allow library suppliers and developers using this format to make their cell libraries ready for a comprehensive signal integrity flow for 130 nanometer(nm) designs and below. Liberty is the most widely used library format in the electronics design automation (EDA) industry and is integral to the design flows of both semiconductor vendors and electronics designers.

"It is imperative that gate-level modeling techniques capture the essence of exact silicon behavior for designers who use deep submicron technologies," said Jean Pierre Geronimi, director of Computer Aided Design at STMicroelectronics' Research and Development. "We have worked closely with Synopsys to develop a noise modeling solution within the Liberty standard that closely mirrors noise effects we are seeing in 90 nanometer silicon."

Leading-edge designers who use silicon processes of 130 nm and below need to be able to isolate and prevent noise problems at the gate level, where they are easiest to fix. Delaying the analysis and repair of signal integrity problems can lead to numerous iterations that severely impact time to market. Synopsys has collaborated with leading semiconductors companies, EDA vendors and library providers to extend Liberty's modeling foundation to enable timing and signal integrity closure.

"As we move to smaller geometries, noise modeling becomes critical. Having signal integrity analysis capabilities in our libraries will help our customers better address deep-submicron design challenges," said Dhrumil Gandhi, senior vice president of Product Technology at Artisan Components. "We have collaborated with Synopsys to define the new noise modeling capabilities in Liberty and will be integrating them into our libraries."

"Our customers have been asking us to continue to refine our EDA tools and industry standards to help them with their tough signal integrity challenges in deep submicron designs," said Kevin Kranen, director of strategic programs at Synopsys, Inc. "With the new noise modeling capabilities, as well as with existing voltage and temperature variation modeling mechanisms, Liberty enables library suppliers and semiconductor companies to deliver broadly-usable, signal integrity-ready views needed for process technologies at 130 nm and below."

Pricing and Availability
The noise additions to Liberty are available immediately and can be accessed at no cost through the Synopsys Technology Access Program (TAP-inSM) web site. A noise-enhanced version of the open source Liberty parser will be available at no cost via the TAP-in website in November 2002.

About Liberty
Synopsys' industry standard library format, Liberty, includes the .lib and .plib formats. Liberty is supported by more than 100 semiconductor vendors in over 750 submicron libraries and by more than 30 EDA vendors supplying over 75 production tools. It has evolved over 13 years along with technology and modeling needs. It is an open, proven format, which can easily be extended to meet the needs of designers.
