Hi,I want to ask about how to install iverilog simulator if I use ChipWhispere in windows jupyter notebook,I see the link http://iverilog.icarus.com/, but after I install one of Icarus Verilog for Windows in the installation guide, I still get this problem below:

Do I do something wrong?

I think you need to have iverilog installed in WSL.
