Your question isn't clear.

If you want to do a comparison as the simulation is running then you need to use something like the unit delay block (if discrete time) or memory block (if continuous time) to keep track of previous values (so that they can be compared to current signal values).

If you want to look at signal traces after a simulation is completed then you need to log the signal(s) of interest.
This can be done in multiple ways, the easiest is to use a To Workspace block, or right click on a signal and select the logging option.

If neither of the above is what you're looking for then you need to make your intention clearer.

Phil.
