rand_soc_dumped can't run twice in a row #487

Open dallinjdahl opened 2 weeks ago

dallinjdahl commented 2 weeks ago

If you run python scripts/run.py tests/ci/randsoc_dumped.yaml twice in a row, it will fail with a cyclic dependency. This occurs because the synth_tool picks up all the verilog files in the directory, including the implemented verilog netlist.

The relevant lines are here: https://github.com/byuccl/bfasst/blob/2e4d3f990b22457d56b503d91bd42f1c68a6de12/bfasst/tools/synth/synth_tool.py#L41-L55

We should either specify all dependencies explicitly, or we should treat dependency directories as untouchable, completely separate from the outputs. I personally think I favor the former.

We need to bring back the design.yaml to be able to include/exclude specific verilog files. We also need to remove the part config from the design yaml parser

The design.yaml is being processed to some degree, because jpegencode was not working and I did edit the config file here: https://github.com/byuccl/bfasst/pull/475/files#diff-2efcc07f81fa96d19d539dfcebe73b02c4b1957119511d376f43fe4c3f9eaec7 I also edited the yaml parser and it compiled again. The synth tool searching for verilog files may/may not be redundant.
