Explicit Connectors in Component BasedSoftware Engineering for DistributedEmbedded Systems Dietmar Schreiner, Karl M. G?schka Vienna University of Technology Institute of Information Systems Distributed Systems Group 2007 Overview This talk is about Component Based Software Engineering components connectors contracts Embedded Systems Software distributed dependable resource constrained Software Development Process Model Driven Development Validation and Verification of Composition Models Contribution We show how to simplify the development of component based distributed embedded applications by introducing explicit component connectors within model driven SE (UML 2). how to support validation of communication properties at model level. which types of contracts are required for model level validation of communication within composed structures. Outline Overview of the Automotive Embedded Systems Domain. Component Based Software Engineering and Model Driven Development for distributed embedded systems. Contract Types in Composition Models. Example Composition with Explicit Connectors and Contracts. Automotive Embedded SystemsOverview Todays vehicle networks are truly distributed electronic systems (70+ nodes (=ECUs) [1]). Cars contain numerous (10+) heterogeneous time or event driven bus systems CAN, LIN, FlexRay, MOST x-by-wire steering aids, ABS, ESP(DSC) remote window and lock control engine control airbag control navigation systems entertainment systems Automotive Embedded SystemsTypical Properties Software is mission critical highly dependable hard real-time typically statically scheduled and bound Lifetime is rather long (10-14 years) modular design exchangeable components (modules) Systems are produced in high quantities (56.3 million cars in 2005) costs have to be small bug fixes are extremely expensive Outline Overview of the Automotive Embedded Systems Domain.
