Thanks Tao and Amin. I am able to add options, but I am not able to assign
it to numROBEntries. I mean when I use this in O3CPU.py:
numROBEntries = options.robsize
it doesn't work, since options module is not defined here. I tried
importing options, but still didn't work. Can you elaborate on how to do
this?
Thanks.
