Btw, the controller from DRAMSim3 does not need an interface connected to
itself (the timings for those models come from DRAMSim3).

Best,

[gem5-users] Re: ISSUES FACING WHILE INTEGRATING GEM5 AND DRAMSIM3

[Mahyar Samani via gem5-users]

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,

[gem5-users] Problem in HMC Simulation

[Veronia Bahaa via gem5-users]

Hello,

I am trying to simulate an HMC memory
when I try using ARM and fs or se modes, I get this error:
 File ".../configs/common/HMC.py", line 297, in config_hmc_host_ctrl
if opt.arch == "distributed" or opt.arch == "mixed":
AttributeError: Values instance has no attribute 'arch'

Any help is appreciated

Thanks,
Veronia
