On the Decomposition of End-to-End Timing Requirements in Distributed Partitioned Automotive Functions 2012-01-0008

The sound decomposition of system level timing requirements, including end-to-end deadlines, into local timing requirements and latency budgets is a key automotive design challenge. In this paper, we analyze the technical and organizational influences on the end-to-end deadline decomposition. We will identify and assess typical design options. From this, we provide two key contributions: First, we provide guidelines for the decomposition and the application of design rules. Secondly, we analyze the specific requirements and specialties of different use cases. The findings of this paper enable optimizations and traceability of timing requirements through the entire Electrics/Electronics (E/E) design cycle. This is a prerequisite for reliable, cost-efficient automotive system design.
