How do I access an S-function in SimCoupler on Simulink?

I want to run co-simulation of Simulink and PSIM. But I cannot find the S-function in SimCoupler that is necessary to do this.

 Do I need to purchase a separate toolbox for this workflow?

To access the S-function in SimCoupler on Simulink, the SimCoupler must be configured with Simulink.

The SimCoupler Toolbox is not a MathWorks product; it is provided by a third-party company, and you will need to purchase it separately.

Once the toolbox is purchased and configured with Simulink, you can proceed with the co-simulation workflow. 

Information about SimCoupler Toolbox can be found in
