Abstract
The SAE Architecture Analysis & Design Language (AADL) is an architecture description language for real-time, fault-tolerant, scalable, embedded, modular multiprocessor systems. It enables the development of highly evolvable systems, early and quantitative analyses of a system's architecture, and evolution of an architecture model for continued analysis throughout the lifecycle. In this tutorial, we provide an overview of the AADL; demonstrate the AADL's capabilities in creating and analyzing component-based models of the task and task interaction architectures of embedded software; discuss interfacing to physical devices; highlight AADL capabilities for predictive analyses of operational characteristics such as meeting deadline, response time, and throughput requirements; and describe how the AADL can discover system integration problems early in a development effort.
