Hello
I also encountered the error you described. In my case it was caused by the
fact that the parameters at the system level (number_of_cores, number_of_L2s,
number_of_NoCs etc.) that had a value of 1 were not described afterwards in
detailed. I see in your XML that you have <param name="number_of_NoCs"
value="1"/> but no description of this component afterwards. Try modifying this
to 0. Also, try to change the values of "homogeneous_cores" and
"homogeneous_NOCs" to 1.
Best regards,
Alexandru Iordan

Subject: Re: [gem5-users] Error when integrating gem5 output with McPAT
Just figured that the McPAT parser script looks for the components "niu",
"pcie" and "flashcontroller", which were not present in the XML file generated
from the m5-mcpat-parser-se.py. After adding some dummy components for these,
the processing moves forward, hitting floating point exception, probably
because of some unexpected value for these components. I will try to debug
using gdb.
I wanted to check if anyone knows how one could generate valid entries for niu,
pcie and flashcontroller in the xml file ?
