  • Added new flow, SynthesisExploration, that tries all synthesis strategies in parallel, performs STA and reports key area and delay metrics
  • Yosys.Synthesis
    • Updated error for bad area/delay format to make a bit more sense
    • Updated internal stat calls to Yosys to pass the liberty arguments so the area can be consistently calculated
    • Removed SYNTH_STRATEGY value AREA 4 -- never existed or worked
