In recent years there is a drastic increase in the road accident. This was mainly because of the drivers inattention. Thus safety of the passengers and the driver became one of the important aspect of automotive industries. Automotive industries developed features that assist the driver to avoid accidents. These features are called Advanced Driver Assistance System(ADAS). These features are implemented using sensors and Electronic Control Unit(ECU). There is need to test and verify the ECU to make sure that they perform the ADAS functions. Hardware-In-Simulation(HIL) testing is used to test the ADAS ECU. It is a testing technique used to test the ECU in a real-time environment.
