Hi Vipin,

McPAT is not the same kind of simulator as SST, DRAMSim, and SystemC, so it
cannot be integrated in the same way. It's not really a timing simulator at
all. You can use gem5's statistics output as the "activity rate" which is
one of the inputs to McPAT. However, the other inputs (e.g., the relative
energy cost of different activations) is not something that you can get
from gem5.

There have been a few scripts created to convert gem5 stats to McPAT files
in the past. However, I do not think that there are any that work with the
current version (21.2) of gem5. You may be able to find one and update it
for your needs.

Cheers,
Jason
