Formal execution semantics for asynchronous constructs of AADL

Abstract

The Architecture Analysis and Design Language (AADL) has been widely accepted to support the development process of Distributed Real-time and Embedded (DRE) systems and ease the tension of analyzing the systems' non-functional properties. The AADL standard prescribes the dispatching and scheduling semantics for the thread components in the system using natural language. The lack of formal semantics limits the possibility to perform formal verification of AADL specifications. The main contribution of this paper is a mapping from a substantial asynchronous subset of AADL into the TASM language, allowing us to perform resource consumption and schedulability analysis of AADL models. A small case study is presented as a validation of the usefulness of this work.

“…So Sokolsky extends the application of ACSR [28] , presents two tools which support AADL simulation respectively to track the resource utilization and analyze the schedulability to determine whether the resources meet the time constraints or not. A subset of the asynchronous Zhou's proposal [29] maps an asynchronous subset of AADL into TASM to support the resource consumption and schedulability analysis.…”
