Hi,

Below four tests are failing ( 1.0 Release)

smoke_test_doe_rand - observing assertion error, mismatch in the data comparison and unable to generate doe test vector file.

Please review the results and let me know If I'm missing anything or if any information is needed.

Thanks, Sai

Hello Sai,

You have several assertions firing here that indicate the presence of X data values in the simulation. Can you do some investigation into your simulation results to understand how these signals are being driven with X values? We aren't encountering these X values in either our published verilator results or in our internal VCS simulations.

My guess is that the test vector scripts are incorrectly copied to the run directory in your environment, or you're using a plusarg that triggers an unsatisfied dependency (e.g. running the sim with +RAND_DOE_VALUES implies a dependency upon the doe_test_gen.py script being available during a sim).

@saikumar0508 are there any updates on this issue? Were you able to resolve the run failures with these pointers?

Hi @saikumar0508 ,

The first two signatures seem to be coming from an env setup issue as Caleb mentioned above.

For the second two tests, we're not able to repro on our end. The tests pass locally and in our regressions. I'm not able to view your logs or waves. Can you debug a little more and post screenshots of the waves with some related signals?

Thanks, Kiran
