September 5, 2012 -- Synopsys, Inc. today announced that it intends to incorporate on-chip variation (OCV) extensions in its open-source Liberty library format, the de-facto modeling standard for IC implementation and sign-off. The new extensions will help standardize usage of the popular stage-based Advanced OCV (AOCV) modeling approach for 40- and 28-nm processes nodes. The final format extensions and ratification as part of the Liberty standard will be completed with the guidance and assistance of the Liberty Technical Advisory Board.

The Liberty library format is the semiconductor industry's most widely adopted library standard used by virtually all EDA implementation, analysis and library characterization tools as the library model exchange for timing, noise, power and test behavior. In May 2006, an industry-wide Liberty Technical Advisory Board was formed to facilitate the evolution of the Liberty library modeling standard. The Liberty Technical Advisory Board functions under the auspices of the IEEE Industry Standards and Technology Organization (IEEE-ISTO). Its 14 member companies represent the broad semiconductor industry including the design community, EDA companies, silicon foundries, and semiconductor intellectual property (IP) companies.

"Standardizing the Liberty format extensions through the Liberty Technical Advisory Board allows the design community and EDA tool suppliers an opportunity to contribute and participate in the standardization process," said Rich Goldman, Vice President of Corporate Marketing and Strategic Alliances, Synopsys. "In the past two years, the Liberty Technical Advisory Board has helped guide the ratification of over 10 new additions to Liberty to improve design for low-power flows."

Availability

The Liberty Technical Advisory Board is expected to finalize and ratify the OCV extensions to Liberty in November 2012, making it available to open-source licensees shortly thereafter.
