I want to create a logic with Subsystems in Simulink like Stateflow without using state machine. What are the alternatives to Stateflow?

Hey everyone,
I want to create a logic with Subsystems in Simulink like a State Machine without using state machine. What are the alternatives to State machine? I would be happy, if you guys help me to this topic. Thanks a lot.

Yes, enabled subsystem might be a solution. Do you think, Multi Switch Port can be also used for this?
With "jump" I mean a system, which can be triggered through signals from other subsystems. And when the input signal ist not more 1 (True), it will be not more triggered.

Use the approach suggested by @Oguz Kaan Hancioglu below, I think you can achieve activating and de-activating subsystems based on conditions. The transition action may be hard to implement but you may not need it.

You can use the switch case block in Port-Subsystem in Simulink Library. You can use the switch case block with the Switch Case action subsystem to make state machine in simulink enviment without Stateflow. You may need to keep in memory the state variable of your state machine.
As a reminder, simulink implements your state machine as a time based system. Stateflow is event triggered system. There is a difference.

They are the same in terms of multiple choice. But since you need to activate/deactivate subsystem block, Switch-case is ready to be used with the action subsystem block.
