Hi Mann, I think you might be confusing accuracy and precision here :). No one, as far as I know, has tried to make the gem5 models cycle accurate…but I'm sure you could if you really tried. The models are, however, offering an arbitrary level of precision based around the notion of an abstract tick. The default Tick is a pico second, so a system running at a GHz would advance ticks a thousand at a time.
I hope that explains it.

Hi all Is GEM5 Cycle accurate? or their is some internal adjustment. because whatever simulation I do, ticks always results in multiple of Thousand. eg @ tick 304265000, @ tick 302535000 -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
