Dear Community,

does there exist a way to use Model Workspace variables instead of Base Workspace variables for variant control?

I would like to avoid using callbacks for variant override.

I wonder why hierarchical symbol resolution ( http://blogs.mathworks.com/seth/2009/02/15/where-does-that-variable-come-from/ ) does not apply for variant control ...

Best regards,

Tilman

I agree to the above. I would also prefer to have Simulink Variant objects in the model workspace.

Where is this limitation even mentioned in the documentation? I don't understand why variables referenced by variant control conditions would need to be present in a specific workspace. Furthermore, even after moving said variables into the base workspace, Simulink throws an error as it's still unable to evaluate logical expressions such as 'and' or '|' or 'not'
