I get the same problem in windows but I was assuming I was doing someting wrong until I saw this, now I don't know what to think anymore... :-S

got it working on windows, just had to select the backend HDL+Yosys (instead of GHDL(module)+Yosys as suggested in the documentation. However I noticed that it only works for vhd files which don't rely on packages

Could you share how did you install/download ghdl?

Could you share how did you install/download ghdl?

I used MSYS2 MINGW64 and installed from the package group mingw-w64-x86_64-eda package the mingw_w64-x86_64-ghdl-llvm and mingw-w64-x86_64-yosys

Could you share how did you install/download ghdl?

I just use Verilog but not VHDL，and I do it like that: ![Uploading image.png…](), ![Uploading image.png…]() should I instll GHDL? And if I need to install mingw-w64-x86_64-eda, my os is windows11 but not linux，waht should I do?

Now, I intrdouce you what I do when I use TerosHDL to write Verilog(don't use HDL language):

1. Install TerosHDL plugin in Vscode.
2. Install make for windows.
3. pip install TerosHDL (I found that someone said When display "Schematic viewer out put:[error] Yosys failed. ", I should sudo pip install teroshdl, [https://soc.ustc.edu.cn/Digital/lab1/verilog_coding/], but my environment is Windows，I tried in superuer cmd pip install teroshdl, but it didn't work.)
4. check for dependencies(all is well ).
5. Configure Schematic viewer: General,Select the backend: YoWASP. Configure Tools: General:Select a tool, framework, simulator... :Icarus

I meet the same problem, and have a try of adding the path of yowasp-yosys.exe to the system path. (for example, C:\Users\xxx\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0\LocalCache\local-packages\Python37\Scripts)

It finally worked.

faced the same issue i think it has to do with yowasp-yosys python activation. modern python doesn't support system pip installations, so creating a venv is the way. but for some reason yowasp doesn't respect the first configuration of python. THIS SHOULD BE FIXED i guess.

for now passing source ~/.pens/teroshdl/bin/activate && before yosys works
