Help with Cryptech ECDSA

[bat52]

Hi,
I am using cryptech ECDSA256 module to experiment with various EDA tools, including siliconcompiler and I am struggling to go forward with the flow.

I hope somebody can help me :-).

For convenience I have posted my work on the following repository
https://github.com/bat52/cryptech

Remote run :

cd pycryptech && export SCPATH=../siliconcompiler/siliconcompiler/ && ./ecdsa256_siliconcompiler.py --remote_en

Result: this particular library uses `include primitives within a module, which I am not sure is allowed by 'vanilla' verilog, yet it is somehow well digested by both icarus and verilator. It seems the included .vh files are not seen by the tool, even though I am sure they were specified as input with chip.set('input', 'verilog',[list_content])

It seems siliconcompiler renames all the source files, therefore the included filename .vh does not exist in the input folder.
For instance here the name of the existing cryptech_primitive_switch file

cryptech_primitive_switch_8ce4f598d363339ddb88ac2b44f69e962c91bd3e.vh

[bat52]

I finally found example prim_fifo_sync, that has include files.
The solution was to add the following line:

chip.set('option','idir',` INC_DIR_LIST)

Preprocessing went through remotely, but stopped with this Error:

This has actually finally worked in remote mode, as I reported here: https://www.linkedin.com/feed/update/urn:li:activity:7044353070171869185?commentUrn=urn%3Ali%3Acomment%3A%28activity%3A7044353070171869185%2C7045769771736276992%29&dashCommentUrn=urn%3Ali%3Afsd_comment%3A%287045769771736276992%2Curn%3Ali%3Aactivity%3A7044353070171869185%29

@bat52 thanks for the update and I'm glad to hear it finally worked for you.
