If you want to simulate some sort of propagation delays, you need to manipulate the signal and not use wait statements. For example, if your sample rate was 1000 samples/sec and you wanted a propagation delay of 1 sec, you would append to the beginning of your signal, 1000 samples. A delay of 2 seconds, add 2000 samples. The picture I've attached uses the square wave generator. It has a sample rate input and a waveform output which makes it simple to do. If you don't want to use the waveform data type, you can just assume a sample rate of 1. You could not use a delay less than 1 in this case.
