Hello Monica, Aravind, and Ipshita
Currently the script in configs/common/MemConfig.py does not work with
DRAMSim3 models. You can create a DRAMSim3 controller using the following
piece of code (ini_path should point the ini file for the DRAMSim3 model
you would like to use):
class DS3MemCtrl(DRAMsim3):
def __init__(self, ini_path):
super(DS3MemCtrl, self).__init__()
self.configFile = ini_path
You can find all these ini files in the ext/dramsim3/DRAMsim3/configs/
Also, I will add support for DRAMSim3 models in MemConfig.py soon. Please
let me know if you have any questions and if I could be of further
assistance.
Best Regards,
