Dear Choi,
I have the same results with you except from Runtime Dynamic. As
Andreas said, you may need to check the stats.txt file and the
GEM5toMcPAT.py python script.

Dear Choi,
there seems to be a problem with your results. If you see the
Runtime Dynamic results, it mentions that they are either inf or
nan. This means that in the xml file that was produced from the
python script, the runtime statistics have not been written properly.
As such McPAT does not compute the dynamic power consumption
based on the runtime statistics produced by the gem5 simulation. It
only computes a maximum power draw (something like a TDP value
instead of a power value related to the program that you are
actually running).
To correct this error you need to check the stats.txt file and
the python script to see whether the version of gem5 that you are
using somehow has modified the syntax or structure of the stats.txt
file and therefore you need to account for these changes when you
parse it with the python script.
Best regards,
Andreas

Dear Νικόλαος Ταμπουρατζής,
Your description is perfect. I was able to get
"mcpatOutput.txt" without any problem like this.
If you don't mind, can I ask you two more questions?
1) How can I get the total power consumption of the processor
from the output file information?
2) Can I see the your "mcpatOutput.txt" file? I want to compare
with my output file.
Thanks for your time.
Best regards,
Choi

_Dear Soonwon,_
_ _
_I had used McPAT v1.3. Specifically, you can do the following:_
_ _
_1) git clone https://github.com/H2020-COSSIM/cMcPAT.git
_
_2) cd cMcPAT/mcpat_
_3) make all
_
_4) cd cMcPAT/Scripts (here you can see the GEM5ToMcPAT.py).
Usage: GEM5toMcPAT.py [options] <gem5 stats file> <gem5 config
file (json)> <mcpat template xml file> -o <output xml file>
_
_Example GEM5ToMcPAT.py $GEM5/m5out/stats.txt
$GEM5/m5out/config.json
cMcPAT/mcpat/ProcessorDescriptionFiles/ARM_AtomicSimpleCPU_template.xml -o
cMcPAT/mcpatNode.xml
_
_To be noticed to replace the correct of the above paths
and the mcpatNode.xml will be produced._
_5) Run McPAT using the mcpatNode.xml from step 4:
cMcPAT/mcpat/mcpat -infile cMcPAT/mcpatNode.xml -print_level 1 >
cMcPAT/mcpatOutput.txt_
_ _
_You may use print_level from 1 to 5 (more detailed output).
In the above example I have used a generic
ARM_AtomicSimpleCPU_template.xml an I tested using the latest gem5
version (v22.1). You may change it according your ARM processor._
_Best regards,
Nikos

_Hello, I read your question, “RISCV Power/Energy Estimation”.
I’m sorry because It is not a answer to your question.
You said that “I got power/energy estimations of ARM and X86 ISAs
through McPAT.”.
I want to measure a ARM core’s power consumption.
I got the gem5 simulations results, “stats.txt”, but I can’t see
the power consumption of cpu.
Can you tell me how you got the CPU power consumption?
Best regards,
Soonwon Choi[1]_
