Building Validation Suites with Eclipse for Model-based Generation Tools
Abstract: The need for the application of validation suites for tools that may be used in safety critical processes that conform to international standards like ISO26262, DO178b,IEC61508 is growing, especially if the output of the tools shall be trusted, e.g. code generators, target compiler, or test tools.
In the talk a method is presented that systematically generates input and expected output values for tools with corresponding ecore models (reengineered or developed) in Eclipse EMF. The specification of the models in the validation suites is done using a DSL (based on xText), the generation of the tests is done using M2M (ATL). The end of the tests is determined using a model-projection mechanism that shows that all elements of the model that are used in reference projects have been tested. The method has been successfully applied by Validas AG to build two different validation suites for different code generators of leading modelling tools used in automotive sector. Further information is published at www.validas.de

Visual Tools for Analysis of Embedded Applications
Abstract: This presentation will explain visual tools for the analysis of embedded and time-critical applications. Short live demos will give an insight into the use of these tools during everyday development. The tools that will be shown are VeriFlux and aicas ThreadMonitor. VeriFlux is a JVM independent static analysis tool for Java thatperforms a program-wide analysis using abstract interpretation. As results, it finds possible run-time exceptions or deadlocks.Several views are used to browse through these errors: A source-code centric view highlights errors at package, class, method, source-codeand byte-code level, while a problem-centric view enables browsing through the errors detected and zooming down to the corresponding source positions. aicas ThreadMonitor enables remote recording of events that occur ina JVM running on an embedded device. These events include thread-switches, Java monitors, garbage-collection, user events, etc. The time-scale of these events ranges from hundreds of nanoseconds up to seconds or minutes, such that data at timeresolutions that are many orders of magnitude apart need to be displayed properly. The techniques used for the visualization andbrowsing through this data will be demonstrated together with specific tools such as worst-case execution time determination froma run-time measurement.

eTrice: a proposed Eclipse project for embedded MDD based on ROOM
Abstract: The proposed Eclipse project called eTrice is introduced. It will be pointed out why ROOM (Real-Time Object Oriented Modeling, Bran Selic et al.) is better suited for the modelling of embedded systems than UML2 - despite the fact that ROOM inspired some new concepts in UML2 like ports and composite structure diagrams. eTrice will not only deliver a ROOM meta-model but also state of the art tooling support with complete code generation in C, C++ and Java. An easily portable run time framework for each supported language and exemplary Hardware/OS combinations are also in the scope of the project.

Morpheus: the first telematics IDE based on Eclipse
Abstract: Mobile Devices main goal is to provide to telematics field an easy way to add an modify features arising from demand. Based on the existing fully functional MCT SDK, Morpheus provides a full telematics IDE for our products using a large set of Eclipse technologies & frameworks. In the presentation, we'll see how we used EMF technology to provide userfriendly editors based on SWT. A GUI editor based on GEF is one of our prior challenge for this IDE, it creates EMF generated XML files that are transformed using XSL into Java classes to reduce users interaction. For testing purpose, and as we speak of embedded software, we created a device simulator plugged into Eclipse Debug tools.

Scaling configuration management: from single embedded device deployment to fully customized multi-customer, multi-device software. A case study
Abstract: In this talk I will show the path we took from an initial application that ran on a specific embedded platform to a software solution that allows the management of customer configurations and supports software packaging and deployment on a whole range of embedded platforms. This talk is a case study of the path we took from from configurable software to customized software.
The following applications were developed by MicroDoc GmbH for SkiData AG.
The initial application is called DEI (Device Enabling Interface) and it is an OSGi, embedded Java application that runs on an ARM, embedded-Linux platform. DEI is a hardware centric framework for running Skidata specific components called Modules, Protocols and Ports. A good example for a Module is a RFID reader, a Protocol can be CRC32, a Port implementation can be USB, and so on. DEI controlls the lifecycle, configuration and interaction of the various components and offers services like lookup and automatic discovery to the application.
The next step is called MDM (Multi Device Management). MDM deals with devices in a N:1 relation instead of a 1:1 relation as it is the case in DEI. Due to the fact that 3rd party equipment often doesn't have enough resources to run DEI on-board, the DEI is run outside of the device on a hardware instance that is powerful enough to run all the necessary instances of DEI.
The final step is called SCM (Software Configuration Management) and addresses the typical problems that arise in a multi-customer, multi-device environment: the management the lifecycle of software components, the management of customer configurations, the packaging and deploying of software compilations. A software compilation is a software distribution consisting of several customized software components, which can be deployed on a device.

Lessons Learned und die Vorteile des Einsatzes von textuellen domänenspezifischen Modellen auf Basis von Open Source-Tools
Abstract: Textual domain specific languages are a strong trend in software development. What experiences are made in SME when introducing model-driven-software development for embedded systems? We will introduce the lessons learned and benefits of open source textual DSL tools from a real industry project. Embedded developers are often concerned about performance problems when using models. However, state-of-the art modelling technologies do not suffer from these impacts. The authors will show how the introduction of MDSD affects requirements engineering, project management, design and implementation. MDSD will not only be discussed from a technical point of view, but from a more holistic project-oriented view.

Sphinx – an Industrial Strength Tool Platform Fostering Model-driven Development of Embedded Systems
Abstract: It is a known fact that embedded system complexity doesn’t stop increasing and model-driven software development turns more and more out to be an adequate approach to keeping this complexity under control. But it is still a major hassle to provide corresponding integrated tool environments which are sufficiently domain-oriented, scalable, and robust. Eclipse as an open and extensible tool platform is a very good starting point but not a solution per se. The Eclipse Modeling Project provides many of the additionally required building blocks but is very fragmented and not up to the point where it could provide the level of tool support embedded system designers expect. The recently proposed Sphinx project is meant to significantly improve this situation. It will be seeded with code from Artop – a platform for creating modeling tools supporting the AUTOSAR standard which has already been deployed at several larger automotive companies. Complementary building blocks will come from the Papyrus project. Sphinx will provide a modeling tool platform enabling IDE-like tool support for specific modeling languages to be developed at reasonable effort and cost. It will leverage and foster the industrial strength known from Artop and head towards a domain- and vendor-independent interoperability layer (backbone) for modeling tools of any kind.
Stephan Eberle works as product development manager at Geensys in France. He leads the development of the core parts in the Artop open source project (www.artop.org) which provides reusable building blocks for Eclipse-based AUTOSAR design tools used in automotive software engineering. He is also committer for the Teneo component in EMF, EMF Search in EMFT, and will be co-lead of the recently announced Sphinx project under MDT. Stephan holds a Ph.D. in Engineering and a Diploma degree in Electrical Engineering, both from the University of Stuttgart (Germany).
How to Improve Your Geographically Distributed Software Development Process using Git or Mercurial
Abstract: Since Linus Torvalds presented his revolutionary invention Git Distributed Version Control Systems (DVCS), its adoption and interest amongst software developers has been consistently rising for such systems. Reaching the limits of legacy version control systems, software developers are seeking alternatives to replace their centralized systems.
Some notable advantages of DVCS like Git, Mercurial and Bazaar over centralized systems:
- More transparency in communication,
- Increased collaboration between peers resulting in improved productivity,
- Better facilitated development processes,
- Less complexity and administration efforts,
- Reduced costs for hardware, support and maintenance costs
- Less network load, less dependence on network
- Working in online / offline mode
Compared to legacy high-end version control systems, the latest DVCS make it easier to collaborate on projects by designing communication more transparent and processes lighter: it's easy to join projects, to understand and integrate changes, and to branch or tag source code. DVCS also provide incomparable performance with large code bases, support offline work, and are inherently built to mitigate against a single point of failure.
In our live presentation, we will demonstrate the development process of a geographically distributed team using Eclipse and Mercurial. With focus on the relevant challenges – complexity handling and costs – we clearly emphasize the achievable results by using a Distributed Version Control System.

Development Organisations of the Future
Hans-Jürgen Kugler, KUGLER MAAG CIE GmbH
Abstract: As the demand for software continues to grow, embedded systems rule. There are few, if any, industry domains that have not yet been “infected” by software. Pervasive computing is already here to stay. And as the internet moves from an information network to a command and control network of “things” the distinction between local and global pervasive computing blurs.
Evolving systems is essentially what we are dealing with, systems with emergent properties. And since these systems are or will control real-life situations, the behavior of these systems better be safe, secure and reliable – to name just a few properties. Evolving critical systems is what Lero, the Irish Software Engineering Research Centre, calls what we are dealing with.
The question is: “Can we deal with these?” Conway’s Law states that the properties of a product are a reflection of the properties of the organisation that developed it. And organisations are essentially defined by the processes they employ to innovate, develop, market, sell and generate revenue from their products and services.
A whole array of international and industry standards, researchers, consultants and trainers aim to address what should constitute processes consisting of “good practices” to guarantee that we get what we wanted to get. Significant progress has been achieved in various industry domains. The trend is to favour a process competence level that is harmonised across an organization and deployed in the majority, or even better, all development situations.
Many see this so-called “Level 3” as an oasis of stability, which allows predictable development and cost optimization. Given the rate of growth and change in evolving critical systems this seems understandable, but incongruous. What necessary is a flexible response, an attitude to embrace and welcome change. Are the current models for organisations and processes suitable? How does such a flexible organisation with adaptable processes work? What is the basis of its development processes, how does its management function – and is there a role that the tool infrastructure could play?
Functional Safety Implications for Development Infrastructures
Abstract:More and more embedded systems are safety-related. In the automotive application domain the health of drivers and traffic participants depends on the correct functioning of such systems. That has implications on the way such systems must be developed, including the development environment and tools used. Functional safety standards describe what and how to do in the different development phases.
We shortly explain the key approach of functional safety standards and then concentrate on the automotive domain with its upcoming standard ISO 26262. We address the relevant elements of the standard concerning development environments and software tools used from the perspective of the tool users as well as of the tool manufacturers. Tool qualification is the key word. It is one thing to know what the standard requires. It is something different to know how to interpret the standard in practice. “What do I really have to do?”

Applying OSGi, Modeling, and Eclipse to Embedded System
Abstract:As embedded systems become more powerful they gain the ability to execute feature-rich complex software applications. Applying modular software and hardware techniques to the design of embedded systems facilitates and speeds up the development cycle. On the software side, OSGi can be used as a standardized software service framework that promotes reusable and easily configurable software. On the hardware side, Bug - a highly modular and configurable hardware platform – can be used to quickly build embedded hardware prototypes. The availability of multiple hardware modules enables the designer to quickly extend and modify the hardware platform. Although frameworks and platforms facilitate the development of these systems, developers can benefit greatly by the application of model driven development (MDD). MDD provides developers with domain specific languages, editors, and generators which enables them to program at higher level of abstraction and closer to their problem domain while shielding them from the idiosyncrasies of the solution domain. Interestingly enough, Eclipse provides a mature industrial-strength commercial-quality implementation of both an OSGi framework (Equinox) and a Language Workbench (Eclipse Modeling Project). A Language workbench provides developers with the necessary modeling tools and frameworks that make MDD an economically viable solution.
During this talk we will discuss the benefits of OSGi as applied to a highly modular embedded consumer electronics system. We will also discuss the techniques required to enable Java OSGi services to communicate with hardware as well how to facilitate the development of the applications targeting embedded systems and OSGi by extending Eclipse. We will include the use of MDD as means to tackle the complexities of the applications and the services that run atop the OSGi framework and the hardware modules.
