I understand you are trying to create a discrete square wave using Simulink. It can be done using Signal Generator and Zero Order Hold block.
You Can Visualize discrete signal by Scope Block with some changed Settings.
Scope >> View >> Style >> Line >> No Line
>> Marker >> ‘o’
I have attached a sample model.

Whether you use zero-hold block or not. But by this step "Scope >> View >> Style >> Line >> No Line>> Marker >> ‘o’" you will directly get the discrete sampled signals.
So, meanwhile signal generator with sqaurewave creates the discrete signal.
