I recommend having a SystemVerilog counter - for now in the TB env (once you implement CSR - you will base it in the FE HW)
You can use XMR (cross module reference) access from the TB to the core HW indications to calculate the differet PMONs (performance monitors).
Example:

  • Data Hazard (with Not Insertion)
  • Jumps
  • Branches (taken or not)
  • in general number of cycle until ebreake
    At EOT (end of test) You can "dump" the "SystemVerilog counter" to one of your logs to get stats on your run.
