TMC-20003: Unconstrained I/O Path

The Compiler does not optimize timing for unconstrained I/O paths.

Recommendation

Constrain I/O path with one of the following external delays to ensure that the I/O path is timed and optimized appropriately:

  • set_input_delay for in2reg
  • set_output_delay for reg2out
