Atomic Subcharts

Encapsulate modal logic in reusable subcomponents

Reuse state components in multiple charts by using atomic subcharts. Generate reusable code from atomic subcharts. Reduce recompilation time for your model by recompiling only the atomic subcharts that you modify.

Model an Elevator System by Using Atomic Subcharts

Model a two-car elevator system by using linked atomic subcharts in Stateflow®. The elevator system consists of a Simulink® model and a user interface (UI). The model contains two Stateflow charts: Elevator System models the core logic that delegates incoming requests from the UI to the nearest available elevator car. This chart contains a pair of atomic subcharts that implement identical logic for the cars.
