Do you have any examples of using VUnit with UVVM?

@GlenNicholls, unfortunately, no and I have looked but couldn't find. However, when I was trying to decide what to learn (VUnit, UVVM) I found that VUnit is much faster to learn. This example requires a lot of work to make it work but the author said that if you know how to use UVVM, it is powerful.

@Ahmad-Zaklouta Yeah, I used both VUnit and UVVM before settling on VUnit. However, I found UVVM frustrating to learn so I didn't get very far. I understand the framework a decent amount, but having access to all of their VVC's in VUnit would be nice simply because VUnit doesn't have as many verification components. Not a huge deal, but I'm sure this is a deal-breaker for some people. The other example I see with using VUnit and UVVM is someone would be able to keep all of their UVVM frameworks, but with a modern test runner for CI.

@Ahmad-Zaklouta OSVVM is also a nice alternative to UVVM and it plays nice with VUnit. OSVVM utility library is a superset of what UVVM provides - in particular, UVVM currently provides the OSVVM Randomization and Functional Coverage packages in their release.

Like VUnit, we do not provide as many verification components as UVVM - at least not yet. OTOH, with respect to the AXI models, OSVVM provides the missing functionality the others do not - specifically the ability to run each of the independent AXI interfaces independently - yet still coordinate them.

@Ahmad-Zaklouta Using VUnit with any other VHDL framework is pretty straight-forward:

• If that framework is setup to stop the simulation on error then you don't have to do anything special. Anything that stops a VUnit testbench before test_runner_cleanup will be a failed test.
• If that framework may complete without stopping on errors, for example if you have a "stop level" set to 3 and only have one error, then you have to read that framework's error counter before just before calling test_runner_cleanup. Something like

check_equal(function_to_read_error_counter, 0, result("for error counter"));

Give it a try and see what happens.

@LarsAsplund I am actually using VUnit only at work and just playing with UVVM. For me, I feel that I got the structure and the idea of VUnit. For UVVM, I am still struggling to get the testbench structure. I feel my way is to focus more on learning VUnit with OSVVM because making this example work took so much time.
