Something seems to have changed in the Synopsys VCS simulator; the Web2.0 world is buzzing this week about the OVM running on VCS. We first saw a post on the LinkedIn "OVM Professionals Network"on Monday June 15. Today we saw a more detailed posting at IntelligentDV specifically stating a released version of VCS that will run the OVM.
For nearly two years we have talked to
many VCS users who wanted to access the reuse and scalability only
found in the OVM. While these user reports do look legitimate, VCS users will have to run their own tests to confirm. It would be great to see an official statement of support from Synopsys, but this blogger can only wonder if that will come before or after a similar statement about e support in VCS. Or for that matter, PSL support in VCS.
Cadence and Mentor have worked hard,
with the help of the nearly 8000 users on the OVMWorld, to assure that one
library can run unmodified on both simulators. We welcome input on any issues VCS users see with the OVM code and recommend posting them to http://www.ovmworld.org/forums/ .
It looks like the OVM has unified the simulator world!
I have tried compiling the examples that come with the OVM source code, with VCS D-2010 version. Some of them get compiled and others show compilation errors in the OVM source code. I did not find any link with official confirmation that Synopsys-VCS supports OVM.
It’s always good to hear from you. Thanks for the more “official” confirmation from Synopsys, but I’d take any unsubstantiated performance claim from them with a boulder of salt. As the product manager for all of our digital simulation business, I can safely say that I see many benchmarks worldwide where Incisive is the fastest solution. So there’s a claim for a claim.
P.S. Any chance your contact can provide more info on Synopsys’ unannounced support of IEEE standard e and PSL?
I spoke to someone at Synopsys that confirmed to me that VCS runs OVM. He also said it runs 2X faster than competing simulators. Care to comment?
