A Design Framework for End-To-End Timing Constrained Automotive Applications

Abstract : In modern cars more and more algorithms are imple- mented as distributed systems. For example, an ACC- System (Adaptive Cruise Control) today requires a min- imum of 5 ECUs (Electronic Control Units): Engine ECU, Gearbox ECU, Breaking ECU, the MMI-Interface, and an ECU operating the radar system. Mastering the overall timing behaviour of such a distributed system is a funda- mental challenge during design. The so-called end-to-end timing from a sensor to an actuator must meet a certain deadline, also claimed by functional safety regulations like IEC 61508 and ISO DIS 26262. In order to fulfil such requirements, the timing on the bus, the ECU-timing, and the timing of the communication controller have to be taken into account.
