With the development of the Automotive Industry, Internet of Vehicles and Autonomous Driving has become an established trend[6]. In order to support the function requirements, more and more Electronic Control Units have been applied on the vehicles. As the core structure of the automotive electronics, Automotive On-board Gateway Controller (GW) can realize the communication and management functions between different ECUs and different bus types, for example CAN, LIN, MOST, FlexRay. In order to ensure the normal working performance of the GW, the test engineer needs to conduct a comprehensive test on the GW before it can be installed on the vehicle.
