More specifically, for the icache and dcache config parameters for McPAT, McPAT expects "throughput w.r.t. core clock" and "latency w.r.t. core clock". In the original template XML file, the values are 1 (hardcoded constant) and "ceil(config.system.cpu.icache.latency / config.system.cpu.clock)", respectively.

Hi Ivan I am following the same link in your post, but I cant get the right xml file for Mcpat to read, could you please show me how did you do this? thank you very much!
