Wow... I guess you learn something new every day. Richard Goering over at SCDSource has just written up a great article on the fact that both Mentor and Cadence now support the VMM. When I wrote about this last week I'd only heard about the Mentor support. One of the best parts of the article is Goering's description of a discussion he had with Karen Bartleson of Synopsys:
Bartleson said, however, that Synopsys has no intent to support OVM. "Our goal is to support the Accellera [VIP] standard, so we get some unification. For us to support OVM would mean more confusion in the industry."
So why is Mentor's support for VMM a good thing for interoperability, while Synopsys support for OVM would sow confusion? "Because VMM has been out there for two to three years in production and OVM was only recently introduced," Bartleson said. "If Mentor supports a more widely accepted, de facto standard, that's good for the industry. If Synopsys supports OVM, which is a new and different implementation, it will fragment things more."
