TomO700 commented 2 years ago

I am trying to modify the default python and run with the following command using verilator, and end up with the error below

Command

SIM=verilator pytest -o log_cli=True test_mod.py

Error

E       SystemExit: Process 'perl' terminated with error 2

Any help would be highly appreciated

I am lost what you are using cocotb-test or python runner from cocotb ? Maybe it was correct repository for the issue after all. BTW: cocotb runner will change a lot still.

It looks like a compilation fail. Not sure why there is no more info in the log file.

In any case please try to run from command line 

perl /usr/local/bin/verilator -cc --exe -Mdir /mnt/D/d/OB_tb/sim_build -DCOCOTB_SIM=1 --top-module ob_top --vpi --public-flat-rw --prefixsv Vtop -o ob_top -LDFLAGS -Wl,-rpath,/home/tomo/.local/lib/python3.9/site-packages/cocotb/libs -L/home/tomo/.local/lib/python3.9/site-packages/cocotb/libs -lcocotbvpi_verilator /home/tomo/.local/lib/python3.9/site-packages/cocotb/share/lib/verilator/verilator.cpp /mnt/D/d/OB_tb/ob_pkg.sv /mnt/D/d/OB_tb/ob_top.sv /mnt/D/d/OB_tb/ update.sv /mnt/D/d/OB_tb/lookup.sv /mnt/D/d/OB_tb/add.sv /mnt/D/d/OB_tb/ cell.sv /mnt/D/d/OB_tb/cell_sort.sv /mnt/D/d/OB_tb/mod.sv /mnt/D/d/OB_tb/ del.sv

Not sure, if the mails reached you or not. I replies about 3-4 days ago. Will either way copy them below I tried the command with a few suggested changes to switches, wondering if it's an installation or a path problem. --prefixsv was changed to -prefix -L & -l were changed to -D

Below is the command and error

Btw, even for the dff example, the below command fails for verilator, but works with icarus

_SIM=verilator pytest -o log_cli=True testdff.py

Problem is I need to use verilator due to lack of support for some sv constructs on icarus.

TomO700 commented 2 years ago

Solved this, reinstalling verilator and also making a change to the $PATH
