How to check correctness of your simulator

We are currently preparing a sample output. While you are waiting for samples if you can answer "yes" for all the following answers, you are mostly likely on the right track.

  • As you increase KNOB_GHR_LENGTH from 4 to 14, do you see performance improvement? (for a long trace)
  • As you increase KNOB_ISSUE_WIDTH from 1 to 3, do you see IPC(1) << IPC(2) << IPC(3) ?
  • As you increase KNOB_ISSUE_WIDTH from 1 to 3, do you see (IPC(2) - IPC(1)) > (IPC(3)-IPC(2)) ?
  • Do you see IPC (inorder scheduling) < IPC (out of order scheduling) ?
  • Do you see in order retirement debug messages for both in order scheduling and out of order scheduling when you turn on debug messages?
  • Do you see out of order issue debug messages for out of order scheduling when you turn on debug messages?
  • Do you see in order issue debug messages for in order scheduling when you turn on debug messages?
