摘要

Today's innovations in the automotive sector are, to a great extent, based on electronics. The increasing integration complexity and stringent cost reduction goals turn E/E platform design into a challenging task. Timing/performance is becoming a key aspect of architecture design, because the platform must be dimensioned to provide just the right amount of computing power and network bandwidth, including reserves for future extensions, in order to be cost efficient. In other words, it must be as powerful as needed but as cheap as possible. Finding this sweet spot is a key challenge. Therefore, OEMs and Tier-1 are in search of new methods, processes, and timing analysis techniques that assist in early platform design stages. In this paper, we demonstrate how some selected techniques that are established for verification (in late design stages) can also be used to guide the design (in early stages). We present examples in the areas ECU (OSEK), buses (CAN, FlexRay) and gated networks. Flow and applicability aspects are highlighted. As a key result, we show that and how we can learn from late-stage verification for early-stage design. Finally, we also outline future challenges in the area of multi-core ECUs.
