Validation of perception systems of ADAS/AD ECUs is a complex task. Apart from real world tests and simulation techniques fully based on software (SiL) it is indispensable for a holistic and consistent test coverage to do hardware in the loop tests.

Supplying a domain controller with multiple Cameras, Radar and LIDAR sensor data is a completely different task than supplying a single high-resolution sensor. Thus, interfaces have to fulfil various requirements for a rapid response in development during prototyping, when only an ECU PCB prototype is existing, to the final validation of a system.

A crucial requirement is temporal correlation of data streams during replay and side-band signals along with GMSL, FPDLink and I²C for the emulation of the perception engine.
This requires an architecture for Hardware in the Loop systems that is looking into an integrative setup of interfaces for single sensors up to a hybrid sensor emulation and data center technologies for big scale domain controllers.
