Success (sort of) - I was able to successfully simulate w/ verilator after I built a new version of verilator from the github repository. This was using MobaXterm running a bash terminal session w/ WSL/Ubuntu 18.04.
I was not able to get run successfully w/ either target=sim --tool= modelsim or target=nexys_a7 when running from Windows 10 even though I installed fusesoc. Here is that error sequence (pardon the dos control characters):

I was able to get further when I tried on WSL/Ubuntu 18.04. Got stymied/stuck because I couldn't get the latest version of verilator. I did sudo apt-get update followed by a sudo apt-get install verilator but apt-get said I had the latest version (3.916). Other than building from source I'm not sure how to get a later version. So, if it won't be possible to get fusesoc working on ubuntu 20.04, a pointer in the direction of how to get a later version of Verilator would be appreciated.
I am hoping that a fix to make this work w/ ubuntu 20.04 is possible.
Thanks Roy

I just started working w/ fusesoc and swervolf and got this error when following the steps in the README.md file. I cloned the repositories today so should have the latest.
I am running ubuntu 20.04 LTS and python 3.8 which I have aliased to python. I've looked through the .core files but I couldn't find what intcon was being generated from. I have Verilator 4.028 2020-02-06 rev v4.026-92-g890cecc1 installed but I don't think I'm getting that far.
