Hi,
I am also curious about how to create new options as well. The numRobEntries in
O3CPU.py you mentioned has the following:
"numROBEntries = Param.Unsigned(192, "Number of reorder buffer entries")"
How is this related to options.robsize as mentioned?
In addition, what if I were to add another data member to a class and want to
use python options to set the value, what additional steps or procedure do i
need to perform? Do I need to do anything with SWIG or something?
Thanks,
Zheng Wu
