Is it possible to use newer versions of Verilator and FuseSOC

[Aaronyap2002]

The version suggested in this repository is 4.104. Is it possible to use version 4.210, or even 5.107? Or should I install 2 versions of verilator? The reason is because i would like to build the docker container according to the instruction in ibex-demo-system, but the verilator version stated in container/Dockerfile mentioned

# Global configuration options.
ARG VERILATOR_VERSION=4.210
ARG VERIBLE_VERSION=v0.0-2135-gb534c1fe
ARG RISCV_TOOLCHAIN_RELEASE_TAG=20220210-1

This caused my docker to continue looping 5/17.

I am worried that if i update to the newest version, i might not be able to build the simulation.

On a side note, I thought of upgrading FuseSOC to the latest one too. Is it advisable to do it?

[utku1998]

I have updated the fusesoc to the latest version (2.3), but now I cannot build the simulation, although it works fine before. Now I get the following error:

Is there a solution for that? And what version should I use? Since, I don't remember what was the version that works, I can't build the simulation again!

[Aaronyap2002]

i checked my version is 0.1. I can't remember how i installed my fusesoc, but yeah i got the 0.1 instead.
Thanks for letting me know about it!

[utku1998]

Now, I have tried with all of the versions listed here: "1.4, 1.5, 1.6, 1.6.1, 1.7, 1.8, 1.8.1, 1.8.2, 1.8.3, 1.8.4, 1.9, 1.9.1, 1.9.2, 1.9.3, 1.10, 1.11.0, 1.12.0, 2.0rc1, 2.0, 2.1, 2.2, 2.2.1, 2.3" and it worked for 2.0. I checked the version and 2.0 was there.

But then when I try to build the system again, I got the following error: "Key 'cores' not found in GAPI structure. Install a compatible version with 'pip3 install --user -r python-requirements.txt'."" Once I installed the requirements, I could build the system. But now, fusesoc --version command prints "0.1".

I did not understand how it worked, but it worked, although there is no version like "0.1" listed there.

[Aaronyap2002]

That's interesting! Have you tried using different versions of verilator as well? Is it possible to share the commands you've used to install different versions of FuseSOC, i would like to replicate it myself too.

[utku1998]

I did not try it. Currently, I am using the version "Verilator 5.018 2023-10-30 rev v5.018-38-g344f87abe".

The commands are:

1. Uninstall the Current Version: pip uninstall fusesoc
2. Install the Desired Version: pip install fusesoc==2.0
3. Verify the Installation: fusesoc --version

Please let me know, if you learn something new!

I also encountered the same problem, please tell me how you solved it?

[thepalbi]

I was able to build correctly simple_system, following the instructions here. First, I got this same error when trying to use fusesoc installed through my package manger (2.3), and then checking how the CI installs it, found that inside the python requirements, a fork of fusesoc is used.

I'd recommend creating a python virtualenv, installing the requirements there, and using the fusesoc version shipped there:

python -m venv env
source env/bin/activate
pip install -r python-requirements.txt
which fusesoc
fusesoc --version # should return 0.1

[Kreijstal]

why is fusesoc 2.3 not supported, why can't the changes be upstreamed?

[Kreijstal]

I just saw the upstream changes of fusesoc, and the changes are ... linting?
