Open a model configured for AUTOSAR code generation, in which you want to activate a runnable based on receiving an AUTOSAR ExternalTriggerOccurredEvent.

For a sample model that uses external trigger event communication, see autosar_swc_fcncalls. In autosar_swc_fcncalls, asynchronous function-call subsystem SS1 models an AUTOSAR runnable. An ExternalTriggerOccurredEvent activates the runnable.

Open the AUTOSAR Dictionary. Select the Trigger Interfaces view and use the Add button to add a trigger interface to the model. In the Add Interfaces dialog box, specify the name of the new interface and set Number of Triggers to 1.

Expand Trigger Interfaces and select the Triggers view. Examine the properties of the associated trigger. For an asynchronous (nonperiodic) trigger, set CseCode to None, indicating an unspecified trigger period. For more information about specifying trigger periods, click the help button in the triggers view.

Expand AtomicComponents and expand the component. Select the TriggerReceiverPorts view and use the Add button to add a trigger receiver port to the model. In the Add Ports dialog box, specify the name of the new port and set Interface to the name of the trigger interface you created.

Select the Runnables view and select the runnable that you want to activate based on receiving an AUTOSAR ExternalTriggerOccurredEvent. In the Events subpane, set Event Type to ExternalTriggerOccurredEvent. To display event properties, select the event name. For Trigger, select the value corresponding to the trigger receiver port and trigger you created.

To complete the trigger receiver configuration, open the Code Mappings editor and select the Functions tab. Select the Simulink entry-point function for the subsystem that models the AUTOSAR ExternalTriggerOccurredEvent runnable. In the Runnable field, select the runnable name.
