Hardware-in-loop (HIL) testing is performed at the validation testing stage. It occurs at the last stages of V-Cycle after the integration testing of the application has been performed.
At this juncture, the application is validated against the requirements based on which it has been developed. Ideally, the application that is to be tested, is put inside an automotive ECU called the Device Under Test (DUT). During validation, the DUT must be tested in an environment where it communicates with the signals of other ECUs in the vehicle.
However, testing an ECU inside a vehicle is not a viable option as it escalates the cost enormously. Moreover, the entire target vehicle system may not be available at the time of testing this application.
HIL testing is the answer to these challenges!
