[Mabdalshakour]

Is there an existing CVA6 bug for this?

Bug Description

In setup-env.sh line 45, VERILATOR_INSTALL_DIR is set to "$ROOT_PROJECT"/tools/verilator which doesn't take the VERILATOR_HASH into account like what install-verilator.sh does in line 40, where it sets it to $ROOT_PROJECT/tools/verilator-$VERILATOR_HASH. That makes verilator unreachable except for running smoke-tests.sh. You can't source setup-env.sh as a standalone.

Maybe I am failing to see the issue but I don't see it on the current latest commit (ab2283c) since the verif/regress/install-verilator.sh script will install the binary in tools/verilator/bin which is the default path in the verif/sim/setup-env.sh script.
Please confirm you are still encountering the issue on ab2283c
