Stateflow User's Guide

Defining an Inherited Stateflow Block

These are essential conditions that define an inherited trigger Stateflow block:

• The chart Update method (set in the Chart Properties dialog box) is set to Triggered or Inherited. (See Specifying Chart Properties)
• The chart has an Input from Simulink data object defined (added and defined using either the graphics editor Add menu or the Explorer). (See Sharing Input and Output Data with Simulink.) The chart sample time is determined by Simulink to be consistent with the rate of the incoming data signal.

Inherited Stateflow Block Example

Simulink can trigger a Stateflow block that is not explicitly triggered by a trigger port or a specified discrete sample time. In this case, the Stateflow block is called by Simulink at a sample time determined by Simulink.

In this example, more than one Input from Simulink data object is defined. The sample times are determined by Simulink to be consistent with the rates of both incoming signals.

The outputs of an inherited trigger Stateflow block are held after the execution of the block.
