How to use the example scripts? about invisispec-1.0 HOT 2 OPEN

Sorry for replying late.

Yes, you can use different configurations IS-Sp/Fu-Sp etc on the same checkpoints.
You can generate a checkpoint using "--take-checkpoints=N --at-instruction" if you want to skip the first N instructions. Please consult complete commands you should use from the gem5 mannual website.
Then you can do detailed simulation using "--checkpoint-restore=N --at-instruction --maxinsts=M" if you want to do detailed simulation for M instructions.
Hope it helps.

Thanks. I'm now using AtomicSimpleCPU to make a checkpoint.
I think it's also needed to set the ruby cache parameters, I think the configuration in the paper is:
