As the saying goes: Those who fail to plan, plan to fail. With that said, I am excited to announce a new module focused on Verification Planning, which has been one of the Verification Academy’s most-requested subjects for new content. The new Verification Planning module is delivered by our subject matter expert, who literally wrote the book on the subject, Peet James. The goal of verification planning … Read More

Mentor/Synopsys Collaboration Bears Fruit Two weeks back I shared information in a blog on collaboration between Mentor Graphics and Synopsys to reduce the number of candidate register packages being considered by the Accellera Verification IP (VIP) Technical Subcommittee (TSC).  Mentor withdrew its candidate when all our requirements were able to be addressed in an update to the Synopsys RAL candidate. As … Read More

Now that the Accellera VIP-TSC has released UVM-EA, effectively narrowing the choice of verification methodologies to UVM or OVM, many people are asking which way to go — OVM or UVM?  The answer depends a lot on where you are in code development and what your risk tolerance is.  The good news is that neither is a bad choice. One thing is certain: OVM is not dead yet.  It will be around for a long time.  … Read More

UVM: Charting the New Territory At this year’s DAC, Accellera introduces UVM (Universal Verification Methodology) to the world at its Tuesday breakfast and panel discussion.  While Accellera may call this “Charting the New Territory,” it is not terra incognita to Mentor Graphics nor to tens of thousands of OVM users.  UVM is at is simplest, just OVM.  If you know OVM; you know UVM. While OVM and … Read More

UVM Layering Package updated from OVM Layering Package In an earlier blog post, I discussed a sequence layering technique that Mentor verification technologists had created and presented on at DVCon 2010, based on OVM.  This package has been updated and tested to work with UVM 1.0 EA and is ready for download. As a reminder, the UVM Layering 1.0 Package, like the OVM one, provides the means to add … Read More

Easier DUT to Testbench Connections This package introduces a very simple class called uvm_container. In this package Mentor shows how to use this class to link a Design Under Test (DUT) and a testbench.  The UVM Container can be downloaded here as a companion to the Accellera UVM 1.0 EA. This extension also introduces the dual top methodology. This methodology isolates the connections between the … Read More

Mentor supplies the first Register Package for UVM As I mentioned in my earlier blog post to disclose Mentor’s support of UVM-EA on the Questa Verification Platform, we would bring forward other OVM elements and make them UVM ready.  We have done this for the OVM register package. For those who are looking at the UVM-EA and want to avail themselves of additional UVM-ready value added elements, you … Read More

The Accellera VIP-TSC makes the Early Adopter release of the Universal Verification Methodology (UVM) available. While Accellera does not use the Latin word Omnimodus in place of the English word Universal, what Accellera does make available is for all practical intents and purposes just OVM.  In April 2010, we made available at www.ovmworld.org an early version of UVM EA.  It has now been updated … Read More

I shared information in my last blog that Mentor’s OVM-EA starter kit could be downloaded and used by those who need to plan a possible move to, or use of UVM.  I pointed out that we uploaded to OVM World two contributions: (1) Mentor’s UVM-EA Starter Kit and (2) UVM-EA OVM Compatibility Overlay Kit. While many have started to take a look at the kits, one use scheme I did not expect to come out of … Read More

Accellera’s OVM version will be called UVM. In adopting OVM 2.1.1, Accellera signaled it will make further changes. The VIP-TSC has … Read More
