Stateflow

Stateflow is an interactive design and simulation tool for event-driven systems. It is developed by The MathWorks.

Stateflow provides modeling and description of items available with which complex processes and links can be created and described in a representation form easily understood. It is tightly linked to MATLAB and Simulink from the same manufacturer.

Stateflow charts enable the graphical representation of hierarchical and parallel state models and the event-driven transitions between individual states. In addition to classic status model elements C code is directly includable.
