This is a work in progress. It has the following issues:

  • Trellis uses INIT parameter for LUT4, and Diamond uses init (note the case difference)
  • SVF files are not generated
  • BIT and SVF files are not placed in the root of build/
  • No overrides are available (probably need some for bitgen?)

This is almost ready, other than for the LUT INIT issue. Actually, I don't think we need the LUTs there in the first place...

@mithro By the way, this is an example of why I am reluctant to add many combinatorial toolchain configurations: just look at the amount of code added here.
