Stateflow

What Is Stateflow?

Stateflow is a graphical design and development tool for control and supervisory logic used in conjunction with Simulink. It provides clear, concise descriptions of complex system behavior using finite state machine theory, flow diagram notations, and state-transition diagrams all in the same Stateflow diagram as described in the following topics:

• Stateflow Is Part of Simulink -- Stateflow integrates with its Simulink environment to model, simulate, and analyze your system.
• Stateflow Is a Finite State Machine -- Stateflow visually models and simulates complex reactive control and simulation based on finite state machine theory. You design and develop deterministic, supervisory control systems in a graphical environment.
• Stateflow Adds Flow Diagrams to the State Machine -- Flow diagram notation creates decision-making logic such as for loops and if-then-else constructs without the use of states. In some cases, using flow diagram notation provides a closer representation of the required system logic that avoids the use of unnecessary states.
• Stateflow Simulates its State Machine -- Easily modify your design, evaluate the results, and verify the system's behavior at any stage of your design.
• Stateflow Generates Code -- Stateflow automatically generates integer, floating-point, or fixed-point code directly from your design (requires Stateflow Coder)

Stateflow brings system specification and design closer together. It is easy to create designs, consider various scenarios, and iterate until the Stateflow diagram models the desired behavior.
