[gem5-users] Re: RISCV Power/Energy Estimation

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

Hi Ayush, if you want you may check my version of McPAT (based on v1.3 with some improvements) and the conversion tool that I include. I have not checked if the latest version of gem5 made any changes to the outputs that it produces, otherwise it should be fine. This is the repository:

[gem5-users] Re: How calculate power in mcpat

Hi, peak power refers to the peak dynamic + total leakage. Peak dynamic is kinda like a TDP value, meaning that it is what a fully active circuit would give you (let's call the scenario a power virus, not an actual working code). When you execute a specific code on your simulator and use the

Dear Weizheng, you are using a quite old version of McPAT. Current version is 1.3. It would be better if you used that one. Now concerning your issues. You need to make sure that the system that you are trying to simulate in gem5 matches with the template that you are trying to use in McPAT. It

Re: [gem5-users] Discussion About Interfacing with McPAT

Hi Yi Shen, there are a few things to consider here. First, gem5 and McPAT work on different levels. gem5 does not include and circuit information nor anything else beyond architectural stuff. On the other hand McPAT requires information that gem5 is simply not in a position to provide. That is
