13.1 EDK - BFM - Several signals getting optimized out in Modelsim


When running a Bus Function Model (BFM) simulation, Modelsim is optimizing out several signals from my design.


There aretwo workarounds for this issue:
  • Change the run.do script to display:
#Compile BFM test modules
do bfm_system.do

#Load BFM test platform
vsim -novopt bfm_system

  • Alternatively, check to see if your modelsim.inihasVoptFlow = 1. If it does, try setting it to 0.
