Suppose that you have functions named f, g, and h in a chart. These functions can be any combination of graphical functions, truth table functions, MATLAB functions, or Simulink functions.

To avoid recursive behavior, do not:

• Have f calling g calling h calling f

• Have f, g, or h calling itself

Follow these rules:

• Use directed event broadcasts with the syntax send(event,state). The event is a chart local event and the state is the destination state that you want to wake up using the event broadcast.

• If the source of the event broadcast is a state action, ensure that the destination state is not an ancestor of the source state in the chart hierarchy.

• If the source of the event broadcast is a transition, ensure that the destination state is not an ancestor of the transition in the chart hierarchy.

  Also, ensure that the transition does not connect to the destination state.
