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
