Hello,
Yes, you can use "simulink.signal" as a variant condition expression.
I see that you have defined objects of "Simulink.Variant". As of the latest release R2024a, you can make use of "Simulink.VariantExpression" objects instead. The structure remains the same as how you have declared the object.
In the block parameters dialog of variant blocks, you can just specify the object name directly in the "Variant condition expression" field. For example, "Variant1" for the first choice and "Variant2" for the second one. When you do that, it would fetch the condition specified from the object and populate the next column (read-only) with the condition expression.
Here's the documentation link for "Simulink.VariantExpression": https://www.mathworks.com/help/simulink/slref/simulink.variantexpression-class.html
