Hi Yuan, The way I simulate DerivO3CPU, (first run)is I run with AtomicSimpleCPU and create a checkpoint after the boot by using command “/sbin/m5 checkpoint” and then run the benchmark.
In my second run I restore checkpoint using AtomicSimpleCPU and then switch to DerivO3CPU. And then I get the final stats using DerivO3CPU.
