The eTrice Eclipse Project aims to provide an implementation of the Real Time Object Oriented Modeling (ROOM) modeling language. It will include editors for creating ROOM models graphically and textually, code generators for Java, C++ and C, and support for model-level debugging and sequence diagram creation from running software. The project is currently in an incubation phase, with prototypes of the ROOM grammar, Xtext editors, and a Java code generator and middleware. The next steps involve initial contributions in December, supporting more modeling capabilities by April, and conducting a pilot industry project by July 2011.

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
 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 event-driven, distributed embedded
systems

Motivation: Why ROOM and not UML2?
 ROOM was developed to suit the needs of event driven
real-time software systems
 ROOM has well defined semantics (e.g. for hierarchical
state machines, message passing)
 ROOM offers powerful concepts like layering and model
level inheritance for structure and behavior
 UML2 is way more complex than ROOM

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

ROOM Editors: Statemachines
hierarchical State Machines define the dynamical behaviour
of Actors

6. © 2010 protos Software GmbH 6 23.11.2010
Model Level Debugging: MSC Generator
The events can be logged on the target to create Sequence Diagrams of
the running application
Logs can be viewed with Trace2UML (http://trace2uml.tigris.org/)
