Refer to the model “slexVariantVnVWorkflow” which provides an example of a Variant subsystem. You can find this at the following documentation link:

https://www.mathworks.com/help/simulink/ug/v-model-for-system-development-with-simulink-variants.html

 

• The Variant Subsystem shown in the model has two choices :

• Open Simulink Test Manager, and click on "New → Equivalence Test"

• Create Parameter Sets

1) Create parameter sets and add the variant control variable with the respective value. Each parameter set aligns with a specific variant control value.

2) In the above example,there are two parameter sets corresponding to the variant control expressions speedConfig = 1 and speedConfig = 2.

3) For Simulation #1 (Normal mode):

4) For Simulation #2 (SIL mode):

5) Create Iterations and run test:
