Describe the solution you'd like Any of the below:

• https://github.com/PyHDI/veriloggen
• https://circt.llvm.org/docs/PyCDE/ (beautiful syntax)

Describe alternatives you've considered Continue building off of the current backend until code generation features that are deemed too complex are required.

Additional context May be challenging to convert the IR expressions to a format supported by these tools.
