Integrated end-to-end timing analysis of networked AUTOSAR-compliant systems
—As Electronic Control Units (ECUs) and embedded software functions within an automobile keep increasing in number, the scale and complexity of automotive embedded systems is growing at a very rapid pace. Hence, the automotive industry has been developing the Automotive Open System Architecture (AUTOSAR) to harness the reusability of common interfaces to communication buses, real-time operating systems and services. These common interfaces foster ease of adoption, interoperability, maintainability, predictability, and analyzability. However, realizing such standards also requires strong support from endto-end design tool chains. In this paper, we describe some key analytical components that together characterize the end-to-end timing properties of hierarchical bus structures composed of FlexRay, CANbus and LINbus. Our analysis shows that the practical constraints imposed by standards such as AUTOSAR can lead to higher levels of schedulable resource utilization. This reduces both the ...
