I can hardly believe it. I’ve been in the EDA business since 1980 when I joined TI’s Design Automation Department after graduating from Cal Poly with my BSEE. Since 1995, much of my attention has been focused on EDA standards. I reached a moment of truth this year when I admitted, albeit reluctantly, that I could be called a standards-lifer. So, I decided it’s time to share my perspectives on what’s going on in the standards arena. Welcome to my blog - I can’t wait to hear from you! VMM Support – 3 of 3
Posted by Karen B on August 14th, 2008
In this week’s SCDSource article by Richard Goering, “Mentor, Cadence VMM support may boost VIP interoperability”, Cadence states they support VMM. With all 3 of the big 3 EDA vendors (Cadence, Mentor, and Synopsys) supporting VMM, I think it’s safe to say that VMM is well-accepted in the industry. ‘Nuff said.

Hi Karen,
I think it’s great that something written in an IEEE standard language now works on three (supposedly) IEEE standard compliant simulators. However, I think that says more for the simulators that anything else though. I’m not really sure we can justifiably infer from this that the VMM is “well accepted”. That’s something that we’ll see over time.
What’s interesting me (and this refers back to my comment on your comment to my title=”blog”>(!)), is that we have clients who are still chosing to roll their own solution rather than use the VMM or the OVM. I wonder if they are trying to say something?
Cheers

David,
As a former EDA customer, I’d say they could be waiting for the Accellera standard to come out, or they might be in the middle of a design cycle.
Hey Karen,
I’m surprised no one from Synopsys has commented on my recent blog post about Goering article…

JL,
What more do you expect from Synopsys that was not already covered in Goering’s article? Are you expecting them to take your ‘e’ bate in your latest blog entry?

Karen,
I’m on record supporting the Accellera committee’s efforts so that we have interoperability between simulators and methodologies / class libraries. No customer wants to get “stuck” with a single vendor solution.
At the same time, I really don’t think anybody is “waiting for the Accellera standard to come out”. The assumption is that any new standard to come out of Accellera will be compatible with existing class libraries, be they VMM or OVM. At a minimum, there should be a fairly straightforward path to incorporate or migrate legacy OVM/VMM code. Otherwise, Accellera is doing no more than creating a third standard.

Harry,
Why do you suppose David’s clients are rolling their own? Do they have proprietary solutions they don’t want to share? What do you think?
