Verilator v5.020 has a bug when building a debug simulator (verilator/verilator#4860). Bumping the Verilator version resolves this issue.

Was there any particular motivation for this bump?

[vighneshiyer]

Running make debug in verilator/sims with Verilator v5.020 causes the issue linked above. You can't compile a debug simulator

Ah nice, Vikram was running into this

@abejgonzalez Could you check on the CI? I'm able to run ./build-setup.sh on the Millennium machines just fine, but the CI fails during the conda-lock step. Maybe the base conda environment needs to be re-installed?

[jerryz123]

The setup-repo step in some other currently running jobs worked fine.
I wonder if this is related to the Error: EBUSY: resource busy or locked failures.

[jerryz123]

I think you just have to manually delete '/scratch/buildbot/actions-runner-7/_work/chipyard/chipyard/software/firemarshal/disk-mount` off the build machines

[abejgonzalez]

LGTM. Pending CI passing.

can you make another release with this fix? latest v1.11 is still on 5.20 which is broken... or maybe update the documentation.

Note that 5.022 has a major bug in force behavior if you are using that [1]. This is fixed in 5.024.
