Abstract
Due to ever-increasing bandwidth requirements of modern automotive applications, Ethernet AVB is becoming a standard high-speed bus in automotive E/E architectures. Since Ethernet AVB is tailored to audio and video entertainment, existing analysis approaches neglect the specific requirements and features of heterogeneous E/E architectures and their applications. This chapter presents a virtual prototyping approach to consider Ethernet AVB in complex E/E architectures, reflecting key features such as static routing and stream reservation, fixed topology, and real-time applications. A comparison with a timing analysis on case studies from the automotive domain gives evidence that the proposed simulation technique delivers valuable bounds for complete sensor-to-actuator chains, enabling automatic system synthesis and design space exploration approaches.

Notes
- 1.
Task in this case could either be a functional task executed on or a message that is currently transmitted over the component.
- 2.
A credit overflow may happen in case of a permanent overloaded link by upper class CBS queues, but should not be allowed, because it is a faulty system design.
