[gem5-users] Re: RISCV Power/Energy Estimation
Dear Andreas and Nikos Thank you very much. I will compare python scripts and my stats.txt. After that If I got the correct output files, how to calculate a total power consumption of core? Is there a equation to calculate a total power consumption?

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. Best regards, Nikos Quoting Andreas Brokalakis via gem5-users : 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.

Dear Soonwon, I had used McPAT v1.3.

[gem5-users] How to measure a ARM core's power consumption?
Hello, I'm new to gem5 and have finished "*Getting Started*" and " *Modifying/Extending*" in the gem5 official documentation. (https://www.gem5.org/documentation/learning_gem5/part1/simple_config/) I create a simple configuration script as in "*Getting Started*". ( https://gem5.googlesource.com/public/gem5/+/refs/heads/stable/configs/learning_gem5/part1/simple.py ) And I changed from X86 to ARM core by referring to "*Extending gem5 for ARM* ". - ... - system.clk_domain.voltage_domain = VoltageDomain() - system.cpu = ArmTimingSimpleCPU() - ... The questing starts here. How to get the power information about the arm core in this simple system, not the full system? I already got a "stats.txt" file, but there is no cpu power information there. Thanks for your time.

Hi Karim,\ \ You can run simulation for a few thousand cycles using m5.simulate(some_amount_of_ticks), then reset stats using m5.stats.reset() and then run m5.simulate again.
