Synopsys Calls, Mentor Raises

Thursday, July 24th, 2008

Not to be outdone, but with much less fanfare and ballyhoo than Synopsys’ donation of its Verification Methodology Manual (VMM) class library to the Accellera Verification IP (VIP) Technical Subcommittee, Mentor Graphics last week donated it’s Unified Coverage Database (UCDB) to the Accellera Unified Coverage Database Interoperability (UCIS) Technical Subcommittee.

Although not as hot a topic in the press and in the blogosphere, this represents a firm step forward in the standardization of the overall coverage driven verification methodology, whether you pray from the OVM or from the VMM hymnal. Whereas ratified or defacto standards already exist for the testbench languages, the requirements and coverage capture tools and formats are still proprietary to each of the 3 major vendors. This prevents the verification management tools of one vendor from being used with another vendor’s simulator. Having a UCDB standard will facilitate portability and enable more innovative solutions to be built by third parties on top of this standard.

Although Synopsys and Cadence have their own unique UCDB format, the basic elements of this standard should be much easier to agree upon without the political wrangling slowing the VIP subcommittee. I also think this is an opportunity for Synopsys, Mentor, and Cadence to show that they really can cooperate for the benefit of their customers and win back some of the goodwill lost in the OVM vs. VMM battle
