Okay, there are several separate issues here:

• First, absolute paths currently don't work on Windows. I haven't used TerosHDL but check if you can get it to pass relative paths to YoWASP. (This is still a bug in YoWASP, just one that might not be trivial to address.)
• Second, there's infinite recursion in shutil.rmtree (called from tempfile.TemporaryDirectory destructor) that happens only when the first issue is triggered. This is Python bug #35144, fixed in bpo-29982: Add "ignore_cleanup_errors" param to tempfile.TemporaryDirectory() python/cpython#24793 (not in a release yet).

Hi, Thanks for responding. TerosHDL developers updated the tool to use relative path
The following commands work

yowasp-yosys -p "read_verilog -sv dsp\rtl\dsp_xcc_v2.v; proc; opt; write_json .teroshdl_yosys_output.json; stat"
yowasp-yosys -p "read_verilog -sv .\dsp\rtl\dsp_xcc_v2.v; proc; opt; write_json .teroshdl_yosys_output.json; stat" 

but this is what TerosHDL calls and doesn't work
yowasp-yosys -p "read_verilog -sv ..\..\..\Documents\Projects\test\frontend\dsp\rtl\dsp_xcc_v2.v; proc; opt; write_json C:\Users\bhara\.teroshdl_yosys_output.json; stat"

I think the doubles quotes cause the issue.

Can you ask TerosHDL developers to contact me directly regarding this issue? (In this GitHub issue, by email, whichever is more convenient.) Then we can work something out.

In commit 4ae03d9 I've changed the path handling so that on Windows, absolute and relative paths with any components would work. (It also improves relative path handling on *nix.) Note that on Windows, paths must be delimited by forward slashes, /, rather than backward slashes, \\; this is due to the way WASI implements path handling.

You can install YoWASP Yosys built from this commit with:

pip install -i https://test.pypi.org/simple/ yowasp-yosys==0.9.post5623.dev232

@BharathS11 Can you please confirm whether you were able to get the updated package to work?

yowasp-yosys -p "read_verilog -sv ..\..\..\Documents\Projects\test\frontend\dsp\rtl\dsp_xcc_v2.v; proc; opt; write_json C:\Users\bhara\.teroshdl_yosys_output.json; stat"

Both of these paths should work since commit 4ae03d9, closing. Please comment if there are still any issues.
