Extracting End-to-End Timing Models from Component-Based Distributed Embedded Systems

Abstract

In order to facilitate the end-to-end timing analysis, we present a method to extract end-to-end timing models from component-based distributed embedded systems that are developed using the existing industrial component model, Rubus Component Model (RCM). RCM is used for the development of software for vehicular embedded systems by several international companies. We discuss and solve the issues involved during the model extraction such as extraction of timing information from all nodes and networks in the system and linking of trigger and data chains in distributed transactions. We also discuss the implementation of the method for the extraction of end-to-end timing models in the Rubus Analysis Framework.
