This title and question are much too brief and non-specific for people to help much, if at all. Can you please give a more complete explanation of what you are trying to understand?

In brief, sample time for the model is the time step at which model will be executed. Suppose for Fixed step discrete model, sample time 1 second, then when you will simulate the model, model will be executed at every 1 second.

Sample time can not be seen in generated code. When you generate the code from the model, RTW will generate it's logic only. It's your responsibility to call the generated function (for eg. mdl_step function) in your scheduler at particular time steps which can be same or different with simulation step time.
