Dem Status Inject

Inject an event failure to test recovery

Since R2022a

Libraries:
AUTOSAR Blockset / Classic Platform / Basic Software / Diagnostic Event Manager (Dem)

Description

The Dem Status Inject block can be configured to instantaneously set the diagnostic status for an AUTOSAR event simulated in the Diagnostic Service Component block. This status value can be configured according to the Unified Diagnostic Services (UDS) standard. Specifically, you can use this block to inject a transient failure into a system to test its ability to recover. This block simulates and responds to other blocks affecting its status to show system recovery.

Examples

Simulate and Verify AUTOSAR Component Behavior by Using Diagnostic Fault Injection

Simulate and verify the behavior of AUTOSAR components modeled in Simulink® that contain calls into the AUTOSAR Diagnostic Event Manager (Dem). You can gain quick testing coverage by overriding the diagnostic status of specific events or verify component recovery by injecting transient event failures.
