stateflow variant states possible?

Is is possible to add variants of a state inside a stateflow diagram, similar to variant subsystems in simulink?

Stateflow has built-in support for variant transitions starting in R2020a. Please refer to the following page:

You should be able to use this to model variant states.

You may want to have a look at Simulink Functions inside Stateflow: https://nl.mathworks.com/help/stateflow/ug/simulink-functions-in-stateflow.html

Try to put a variant subsystem inside the Simulink Function. I have not tried it myself, but this would be the first thing to try.

Thanks, but unfortunately this is not possible for me.

I need to generade HDL code for the stateflow diagram, and simulink functions inside stateflow are not supported for HDL code generation.

I think this should be a feature precisely as the questioner suggests. I wonder if you might use a simulink variant on one of the state flow transitions to achieve the change in behaviour (probably not as nice as using the variant idea suggested)
