Automatic Gateway Prototype Generation for Optimization of E/E-Architectures Based on High-Level Models 2011-01-1029

To fulfil the increasing requirements of electric/electronic architectures in automotive environments new concepts for future Electronic Control Units (ECU) are needed. Novel hardware architectures offer much higher potential compared to standard microcontroller devices. In previous publications the advantages of modular gateway architectures over standard microcontroller solutions were shown, especially regarding performance, low latency times, busload independency and configurability. However developing hardware gateway configurations is neither convenient nor practical. But recent development showed a trend towards early e/e-architecture models in tools like PREEvision which are usually used for architecture exploration. In this contribution we demonstrate an approach that closes the gap between such modeling tools and the reconfigurable gateway architecture. Based on our framework automatic generation of high performance gateways even in very early development phases is now feasible. We also demonstrate and discuss the low amount of additional modeling effort being necessary for “automatic-generation-ready” models.
