Synopsys Releases Proven VMM Methodology Standard Library and Applications Under Apache Open Source License
VMM Available for Free Download from New 'VMM Central' Web Site

MOUNTAIN VIEW, Calif., May 28 /PRNewswire-FirstCall/ -- Synopsys, Inc. (NASDAQ: SNPS), a world leader in software and IP for semiconductor design and manufacturing, today announced it has released the source code for its complete implementation of the proven VMM verification methodology for SystemVerilog, including the VMM Standard Library and VMM Applications, under the popular Apache 2.0 open source license. Synopsys' implementation of the VMM methodology, originally defined in the Verification Methodology Manual for SystemVerilog, was recently donated to the Accellera standards organization to speed development of verification interoperability standards. By releasing its implementation of the VMM methodology, Synopsys has enabled users and vendors from across the industry to take immediate advantage of the years of investment in VMM methodology development as Accellera begins its standardization efforts. Synopsys' complete implementation of the VMM methodology is available as a free download at

"With the daunting complexity of today's SoCs and their associated testbenches, it's increasingly important that development teams deploy re-usable Verification IP that is designed to interoperate at the SoC level," said Paul Tobin, director of AMD's Verification Center of Expertise. "Synopsys' open sourcing of VMM and its donation to Accellera for consideration by the VIP technical subcommittee are positive steps towards the standardization and open interoperability between EDA tools that users need."

"By releasing its VMM implementation under the Apache license, Synopsys is inviting the entire industry to use the same proven methodology successfully deployed on hundreds of projects around the world," said Manoj Gandhi, senior vice president and general manager of the Verification Group at Synopsys. "This move supports Accellera's verification interoperability objectives by enabling users to more easily share VMM environments and components as Accellera develops a verification interoperability standard."
