Error : Powerplay Power Analyzer

In that case, try simulating for a shorter period of time, try it with a small amount data first. That way you can see if the file is just too big. I was able to feed in a file of size up to 5 GB.

Good luck and please post how it turns out for you.

By the way, I use the same command vcd add -r /top/dut/* during my simulation but didn't get a High confidence level. I'm still trying to figuring out why, but I do see that toggle and static rate from my simulation file is at about 60%.
