How to wait a certain time in a funtion block?

The thing is that I have a funtion block that measures the value of a signal, but this signal has a transition time and a stabilization time and I want the funtion block to measure the signal when it is already stabilized.

My idea is to put something that makes me wait until the signal stabilizes. Or how could I do it independently of time?

I already tried "pause" but this command stops the execution of all the simulation not only of the funtion block.

Thanks in advance.

this is te signal that i mentioned.. is the input of my function block.
