Diagnostic Fault Injection for Coverage Testing AUTOSAR Components

The AUTOSAR standard defines Basic Software (BSW) services that run in the AUTOSAR run-time environment. The services include Diagnostic Event Manager (Dem), Function Inhibition Manager (FiM), and NVRAM Manager (NvM) services. In the AUTOSAR run-time environment, AUTOSAR software components typically access BSW services using client-server or sender-receiver communication.

Learn about a function inhibition integration model, which integrates two sensor components, a monitor component, and an operation cycle component. The sensor components call BSW FiM and Dem (and NvM) services, the monitor component calls BSW FiM and Dem services, and the operation cycle component calls a BSW Dem service. Then learn how AUTOSAR diagnostic faults can be defined in a test harness to better simulate and verify component models using basic software services.
