MDE: Model Driven Engineering of Embedded Software

Person in charge: Jean-Marc Jezequel (mail)

Pedagogical team: Jean-Marc Jezequel, Benoit Combemale, Benoit Baudry (mail)

Description

Due to ongoing advances in hardware, embedded software has been growing in size and complexity at an exponential rate for the past 20 years, pleading for a component based approach to embedded software development. However, embedded software components interact among themselves and with the real world in complex ways involving many extra-functional dimensions. Like in other sciences, people have been relying more and more on modelling to try to master this complexity. Modeling, in the broadest sense, is indeed the cost-effective use of a simplified representation of an aspect of the world for a specific purpose. Model-Driven Engineering (MDE) can be defined as a software development method where all the relevant information in the project is stored in some kind of abstract model. Software design and validation is then carried out as a set of model transformations.

The goal of this course is to provide the fundamentals of Model Driven Engineering (MDE), organized around the notions of Aspects and Models, Meta-models, and Model Transformations, as well as introducing general principles of Component Based Embedded Software (component and composition models, contracts and assume/guarantee reasoning). In the context of Embedded Software Product-Line Engineering, students will be able to use MDE to mechanize software engineering activities ranging from requirement analysis, aspect weaving, design pattern application, product derivation, to code generation and design validation and verification through a connexion to model-checking techniques as described in the TVA module.

Keywords: Aspects, Models, Meta-models, Model Transformations, Components, Contracts, Product-Lines, Validation and Verification.

Prerequisites: OO Modeling (inc. Class Diagrams, Component Diagrams, Statecharts, Message Sequence Charts, etc.) ; OO Design, programming and testing (main design patterns, either Java/C#/Eiffel/C++ languages, JUnit/C#Unit testing frameworks)

Evaluation mode

Evaluation is based on quizzes, reviews, and/or other academic exercises mostly outside scheduled class times.
The final grade is determined by performance on:

  • one homework: 50%
  • the oral presentation of the homework: 20%
  • one quizz (60 minutes): 30%
