I have a model in Simulink that uses the `Random Number` block. This `Random Number` block uses a `Seed` value for the generation of random values. Now if I have multiple copies of my model:
main.slx
|
|-----> child_1.slx (Random Number block inside)
|
|
|-----> child_2.slx (Random Number block inside)
|
|
|-----> child_3.slx (Random Number block inside)
How can I set the `Seed` of `Random Number` to be different in each copy?

  1. In Child model --> Create Model parameter for seed.
  2. In "Model Block" in Parent model --> Pass the seed value in "Model Argument" field
Please check Parameterize Instances of a Reusable Referenced Model for details.
