Abstract

The Architecture Analysis and Design Language (AADL) is an SAE International Standard dedicated to the precise modeling of complex embedded systems, covering both hardware and software concerns. Its definition relies on a precise set of concepts inherited from industry and academics best practice: clear separation of concerns among layers, rich set of properties to document system metrics and support for many kind of analysis: scheduling, safety and reliability, performance, but also code generation.

In this tutorial, we will provide an overview of AADLv2 and illustrate how several analyses can be combined on an illustrative example: a radar platform.

The tutorial will illustrate the two key dimensions of AADL:

  1. a modeling process, following a system engineering approach: elicitation of high-level requirements and corresponding architecture, refinements and then full implementation,

  2. connection with various analysis down and up the traditional engineering V-cycle.

The tutorial will cover both language and state-of-the-art tools: OSATE2, Cheddar and Ocarina and connections with other modeling frameworks and tools like Simulink, SCADE or OpenFTA.

We will illustrate how to merge various modeling and analysis concerns using AADL: validation of mission-level objectives, high-level system validation, verification of schedulability and reliability and then discuss alternatives to generate part of the system. Motivation for the tutorial

AADL is notation which is part of the model-based families, along with OMG SysML, MARTE or AutoSAR. It has been defined with a strong focus on analysis capabilities from its inception, while being versatile enough to be applied to a wide set of embedded systems. European projects (FP5-ASSERT, TASTE, Flex-eWare), but also US projects (SAVI, Meta) demonstrated that AADL could help engineers in their design effort in the space, avionics and embedded domains.

In the mean time, the academic community adopted AADL as a conveyor to bind numerous tools, covering model checking, scheduling, power evaluation or simulation capabilities to name a few. The AADL committee pages list more than 200 publications around AADL illustrating the variety of analysis being implemented.

The motivation of the tutorial is two-fold: 1) to underline the value of model-based as a viable solution to support design activities of embedded systems, but also 2) to illustrate how to extend AADL capabilities to meet specific project requirements.

List of topics to be covered

The tutorial will cover the following topics: 1. Introduction to the AADL, history and key concepts (1 hour) 2. Presentation of the case study, analysis challenges (30 minutes) 3. How to map AADL concepts onto an analysis domain, illustrations on a scheduling analysis (45 minutes) 4. From model to code: code generation strategies, connection with external behavioral models (Simulink) and code (45 minutes)

All topics will be illustrated through demonstration of tools; the models and the tools will be made available to participants and on author’s pages. Form of the tutorial

The tutorial will have the form of a lecture, with hand-outs and tools made available to participants. We will not ask participants to run the tools, but instead rely on interactive discussion while enriching the various models.
