Exploring Timing Model Extractions at EAST-ADL Design-Level Using Model Transformations

摘要

We discuss the problem of extracting control and data flows from vehicular distributed embedded systems at higher abstraction levels during their development. Unambiguous extraction of control and data flows is vital part of the end-to-end timing model which is used as input by the end-to end timing analysis engines. The goal is to support end-to-end timing analysis at higher abstraction levels. In order to address the problem, we propose a two-phase methodology that exploits the principles of Model Driven Engineering and Component Based Software Engineering. Using this methodology, the software architecture at a higher level is automatically transformed to all legal implementation-level models. The end-to-end timing analysis is performed on each generated implementation-level model and the analysis results are fed back to the design-level model. This activity supports design space exploration, model refinement and/or remodeling at higher abstraction levels for tuning the timing behavior of the system.
