eTrice: a proposed Eclipse project for embedded MDSD based on ROOM

  1. 1. The eTrice Eclipse Project Thomas Schütz & Henrik Rentz-Reichert Protos Software GmbH Eclipse Summit Europe 2010, Ludwigsburg
  2. 2. © 2010 protos Software GmbH 2 03.11.2010 Motivation: Why ROOM and not UML2? UML2 Meta Model ROOM Meta Model
  3. 3. © 2010 protos Software GmbH 3 03.11.2010 Motivation: Why ROOM and not UML2?  UML2 is too complex for some/most projects  UML2 tools are very costly to build and maintain  UML2 was not designed for embedded systems  UML2 is not very specific about semantics 0 100 200 300 400 500 600 700 Classifiers Classes Structural Features References Attributes Operations ROOM UML2.1
  4. 4. © 2010 protos Software GmbH 4 03.11.2010 Scope of eTrice  provide an implementation of the modeling language Real Time Object Oriented Modeling (ROOM)  build ready to use editors for ROOM models (textual and graphical)  create code generators and portable target runtime libraries for Java, C++, and C (and …)  provide built-in support for model level debugging of the running target software: state machine animation, data inspection and manipulation and message injection  provide built-in possibilities for sequence diagram creation from the running software  support heterogenous distributed systems out of the box  eTrice is a Modeling Toolset for eventdriven, distributed embedded systems
  5. 5. © 2010 protos Software GmbH 5 03.11.2010 Hierarchical Components called Actors define the Structure of a System ROOM Editors: Actors & Ports Ports are the only Interfaces of an actor and define a specific role in its environment. Graphical Editors (Graphiti) Textual Editors (XText) Models can be edited with graphical or textual editors
  6. 6. © 2010 protos Software GmbH 6 03.11.2010 ROOM Editors: Statemachines hierarchical Statemachines define the dynamical behaviour of Actors
  7. 7. © 2010 protos Software GmbH 7 03.11.2010 Model Level Debugging: MSC Generator The events can be logged on the target to create Message Sequence Charts (MSC) of the running application Logs can be viewed with Trace2UML (
  8. 8. © 2010 protos Software GmbH 8 03.11.2010 Project Plan: Current Status Organizational:  incubation phase  gathering of community Technical:  precursor tool Trice since 1998 -> new implementation with Eclipse  prototype:  ROOM grammar for static structure and behaviour  XText editors  codegenerator and middleware for Java  first graphical editor (Actor Structure)
  9. 9. © 2010 protos Software GmbH 9 03.11.2010 eTrice Demo
  10. 10. © 2010 protos Software GmbH 10 03.11.2010 Project Plan: Next Steps Organizational:  initial contribution in November  gathering community Technical:  Version 0.1 in January or February  Support for modeling of Structure, Behavior and Inheritance (also for FSMs)  Generators and Middleware for Java  Later: Generators and Middleware for C++ and C  First industry pilot project until july 2011, maybe earlier
