Mapping AADL models to a repository of multiple schedulability analysis techniques

Abstract

To fill the gap between the modeling of real-time systems and the scheduling analysis, we propose a framework that supports seamlessly the two aspects: (1) modeling a system using a methodology, in our case study, the Architecture Analysis and Design Language (AADL), and (2) helping to easily check temporal requirements (schedulability analysis, worst-case response time, sensitivity analysis, etc.). We introduce the usefulness of an intermediate framework called MoSaRT, which supports a rich semantic concerning temporal analysis. We show with a case study how the input model is transformed into a MoSaRT model, and how our framework is able to generate the proper models as inputs to several classic temporal analysis tools.
