Corrupted lowrisc_prim_abstract_xx RTL files

Hi, I am building the Ibex demo system in windows and successfully built the software. While running the command for synthesis

fusesoc --cores-root=. run --target=synth --setup --build lowrisc:ibex:demo_system

The output from command-line is as in the attached file - cmd_output.txt

This generated the prim_xx.sv files that are corrupted and providing syntax errors. I am attaching two of such generated files (uploading copied txt files since sv files cannot be uploaded) - prim_and2.txt prim_buf.txt

Could you please assist me with this issue?

I found the issue, that, the files generated using verible parser created problem whereas, that of regex parser are proper. Is there any way, that by default to bypass the verible parser without much modification to the code?

Yes, those files don't look good to me.

Here's an example of my generated prim_and2.sv:

Are you running on Windows Subsystem for Linux?

[marnovandermaas]

There may be some hints on running the demo system on Windows in the labs: https://github.com/lowRISC/ibex-demo-system-labs/blob/main/lab1.md#windows https://github.com/lowRISC/ibex-demo-system-labs/blob/main/lab1.md#set-up-container-windows

I am building it for Windows using command-line, not in WSL.

[marnovandermaas]

Windows command line is unlikely to work. I recommend switching to WSL.
