Historical Perspective In my early days of standards development, I was intrigued how a standard went from the development phase to use phase.  New standards were heralded with great fanfare but were also followed very quickly with books and other material to allow the “mere mortal” to understand what the IEEE standards prose meant and how best to use it.  Everyone had their favorite VHDL book and … Read More

System Standards Worlds Initiate Unification Accellera, who brought us SystemVerilog, and the Open SystemC Imitative (OSCI), who brought us SystemC have made known their intent to unite to form a single front-end electronic design automation (EDA) standards organization.  You can read their joint press release here. While this may come as a surprise to many, one thing has remained … Read More

Standard Co-Emulation Modeling Interface (SCE-MI) 2.1 Improves Verification Productivity The Accellera Interface Technical Subcommittee (ITC) completed version 2.1 of the standard used to interface software and hardware-based verification technology.  With SCE-MI, models can be developed for simulation to run in an emulation environment and visa versa. The major addition to SCE-MI 2.1 is support … 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

Mentor Announces Collaboration with Synopsys on Joint Register Package Candidate Mentor has recently teamed with Synopsys to collaborate on the Synopsys RAL candidate to provide extensions that meet our register package requirements.  Because of this, it allowed us to withdraw our candidate from consideration by the Accellera VIP-TSC recently. Further, as part of the Accellera VIP-TSC UVM development … 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

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

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
