VMM

Scott Roland, Verilab Inc, Austin, TX As a verification engineer, it is common to be given a design to test that is based on earlier design. Presumably, that existing design also comes with a proven verification environment and suite of tests. Unfortunately, the legacy verification environment might be rather rudimentary. If we are going to create a modern, VMM-based, verification environment for the new design, then what can and should be done with the existing “simple” tests?

Today’s post was written by my colleague Asif Jafri. Enjoy! JL by Asif Jafri Asif Jafri is a verification engineer at Verilab. This post introduces the VMM implementation of the Transaction Level Modeling (TLM) 2.0 specification of how you can connect multiple broadcasting ports to the same receiving export using peer ID’s. Figure 1 shows multiple initiators communicating with the same target. The initiators can be monitors on either side of your DUT passing transaction to a single scoreboard which keeps track of the transactions and does various checks.

Janick Bergeron Synopsys Fellow I am pleased to see that the OpenSource version of VMM 1.2 is finally released. It is the culmination of six months of hard work by the entire VMM teams and the hundreds of customers who have provided inputs on its requirements and the dozens of teams who have contributed their feedback during the beta period. What is new in VMM 1.2 is a “secret de Polichinelle“. Ever since the start of the beta period, several VMM users and Synopsys engineers have published tutorials, seminar presentations and blog articles on many of its powerful aspects.

Fabian Delguste / Synopsys Verification Group I’m very pleased to announce that VMM 1.2 beta is now available. You’re welcome to enroll our VMM 1.2 Beta program by signing up the form on VMM Central at: http://www.vmmcentral.org/cgi-bin/beta/reg1.cgi As you know, the VMM methodology defines industry best practices for creating robust, reusable and scalable verification environments using SystemVerilog.
