Hi all, Just to clarify, if you want to see what clock speed the CPU was run at, the best place to look is in the m5out directory where you have a config.ini/json/dot that contains a snapshot of all the parameters that were used. In this particular case, sim_ticks in not in cycles, so you would have to divide this value with the CPU clock period.
