The eTrice Eclipse Project aims to provide modeling tools for embedded systems using the Real Time Object Oriented Modeling (ROOM) language. It will include graphical and textual editors for ROOM, code generators for multiple languages, and debugging support. The project is currently in an incubation phase, with prototypes of ROOM editors and code generation for Java. Future plans include expanding language support and gathering an open source community to contribute to the project.

Motivation: Why ROOM and not UML2?

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

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

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. © 2010 protos Software GmbH 6 03.11.2010
ROOM Editors: Statemachines
hierarchical Statemachines define the dynamical behaviour
of Actors

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 (http://trace2uml.tigris.org/)

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)

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
