UVVM on IEEE Standards Association Open Source platform

UVVM is now an IEEE Standards Association Open Source project.

In fact, UVVM has been an IEEE open source project for some time already, but we wanted to publish this at the same time as we publish that a 'UVVM working/advisory group' will be established.

The group will be following the policies of the IEEE standards Association and cooperate to make UVVM the best possible verification library and methodology for VHDL designers in order to speed up FPGA and ASIC development and improve product quality.

The group will consist of users with a strong interest in UVVM, and a passion to achieve the above goals for the VHDL community.

UVVM on IEEE is a logical follow-up on one of the main ideas of UVVM – to standardise the VVC architectures and interfaces to allow verification models from any UVVM user to work inside any UVVM based testbench.

Establishing such a group is a logical follow-up for a 100% open source verification methodology and library – like UVVM. We are now preparing for this and will provide more information soon.  

UVVM is an open source verification tool developed and sponsored by leading industry actors.

Important notices

Known bugs:
Modelsim/Questa2019.2 does not work with UVVM. Do not use this version. Previous and laterversions work fine.
