Dennis Brophy Download OVM Configuration and Virtual Interface Extensions from OVMWorld.org Creating configurable testbench elements is critical for reuse. If you write some OVM code in one particular testbench and never intend to use it in any other testbench, then there is no need to make it configurable. As soon as you wish to take code and turn it into reusable IP which can be used in a variety of applications, … Read More

So, I decided to work up a draft blog on debugging. However, this morning, when I was preparing to post my blog, I noticed that Richard Goering … Read More

Tom Fitzpatrick I see that Synopsys has finally released VMM1.2. Congratulations, guys. There will be plenty of opportunity over the coming weeks to discuss the relative merits of OVM vs. the OVM features that have been “borrowed” and jammed into this new version of VMM, (factory, phasing, hierarchy…) but I’d like to talk a bit in this post about Synopsys’ unique approach to version numbering. Let me just say that … Read More

Dennis Brophy SystemVerilog proved to be a “royal flush” of a reason 100’s of people to gather together. Leaving poker references behind, two SystemVerilog User Group meetings were held in India in November. The Cliff Cumming’s “fan club” came out in force at both the Noida and Bangalore locations. When nearly 100% of those who registered showed up at the Noida event, I was almost certain we would have the same … Read More
