Make V2X use Surelog instead of Yosys #64

Open mkurc-ant opened 4 years ago

mkurc-ant commented 4 years ago

There is an idea to switch Verilog parsing/elaboration "backend" to Surelog. Surelog can store an elaborated design in UHDM format which would need to be parsed by V2X.

I think that it would require an (almost) complete re-write of V2X code since it is now heavily relied on JSON data structure delivered by Yosys.

I see the benefits of switching to Surelog:

Support for parsing of things that Yosys doesn't (like attributes on parameters)
Support for System Verilog

I'm not exactly sure what information is stored in UHDM and if it isn't missing important things that we need in V2X.
