The recently completed 47th DAC in Anaheim proved to be the “coming out party” for Accellera’s nascent Universal Verification Methodology (UVM) efforts.  Of course, there has been a core of people who have been working on and/or following the development of UVM, but DAC provided a venue to let the entire community learn about UVM.

To help spread the news about UVM 1.0 EA and future releases, Tom Alsop of Intel and Hillel Miller of Freescale (co-chairs of Accellera’s VIP Technical Subcommittee) gave ½ hour presentations at both the Cadence/Mentor-sponsored OVM-UVM booth and the Synopsys-sponsored Standards Booth.  A copy of the slides used by Tom and Hillel can be found at  Both presentations were quite well attended, and multiple clarifying questions were asked by the attendees.

UVM was also the focus of an Accellera Breakfast panel discussion, sponsored by Cadence, Mentor and Synopsys.  The panel, moderated by Gabe Moretti of the “Gabe on EDA” blog, featured six very technically focused participants: Mohamed Elmalaki of Intel, Hillel Miller of Freescale, Stacey Seacatch of Xilinx,  Janick Bergeron of Synopsys, Tom Fitzpatrick of Mentor and Sharon Rosenberg of Cadence.  The panelists focused less on the history of UVM, and more on the internals of UVM technology and the technical path they wanted UVM to follow.

A measure of the interest in UVM can be gained by observing that the panel was a “sell out”—I saw very few empty seats, and I would judge attendance at between 100-150.  Very impressive for a panel starting at 7:30 AM the morning after the Denali party.

UVM was also the topic of a session in Synopsys’ Conversation Central.  In this session, the audio for which can be found at,  JL Gray of Verilab questioned Tom Alsop and Hillel Miller on multiple facets of UVM.  I was only able to hear the first part of the session, but I did hear JL asking user-oriented questions focused how a user can migrate from OVM or VMM.

The type of questions asked by JL were perhaps the most important asked at DAC with regard to UVM, because the answers can help remove the “fear factor” associated with migration to UVM.  As Tom and Hillel expertly detailed, migration from use of OVM to UVM is straightforward, since UVM has been based on OVM.  Moreover, VMM users have not been neglected, since there is now a VMM-UVM Interoperability library available from Accellera.  Thus, Tom and Hillel assured the audience, no matter whether starting from an OVM or a VMM environment, a smooth migration to UVM is there by design.
