Control Logic Design

Communication engineers develop control algorithms to control the:

• media access controller (MAC)
• logical link control (LLC)
• data link, user interface
and other event driven elements of a system.

Finite state machines are an effective technique for modeling event-driven or reactive control logic, such as initialization and link protocols.

Stateflow® software enables you to design event-driven control logic. It models finite state machines as graphical state diagrams or truth tables in the Simulink® environment. Stateflow blocks can be triggered by Simulink signals. They make decisions based on Simulink signals, call MATLAB® code and C code, and output data and events to control the rest of the Simulink model. The ability to incorporate both the PHY and Control Logic in the same model reduces design risks. With the animation features of Stateflow, you can visualize state transitions and relate these to system signals.
