Abstract
Graphical model-based system design is very appealing and a natural evolutionary step following
from machine code over assembler to higher level textual programming languages. Graphical modeling
languages have been in existence for several decades now, and much progress has been made regarding
their syntax and semantics. However, graphical modeling is still not the rule in system design. We believe
that one explanation is the so far rather limited exploration of modeling pragmatics. This area includes
the actual editing process, the visualization of complex graphical models, visualization of model behavior,
and user interaction, i.e. the mechanics of model editing, browsing and simulation.
The Kiel Integrated Environment for Layout for the Eclipse RichClientPlatform (KIELER) is a test bed
for the exploration of modeling pragmatics. A guiding principle is to avoid effort-prone manual tasks
in the graphical layouting that instead can be done automatically by the modeling environment. The
automatic synthesis of graphical model layouts enables a wide set of novel modeling paradigms that help
the developer to cope with the complexity of real-world applications.
The predecessor of KIELER used built-in simulation engines for a small set of graphical modeling
languages. KIELER aims to broaden the approach and to support a wide set of graphical Domain Specific
Modeling Languages (DSMLs). To this end, we are currently investigating how to leverage the wide range
of capabilities and DSMLs already offered by Ptolemy. Concretely, Ptolemy may serve as a simulation back-
bone for multiple different DSMLs. In short, one may say the Ptolemy provides the modeling semantics,
and KIELER supports the pragmatics; accordingly, we refer to this pro ject as KIELER leveraging Ptolemy
semantics (KlePto).
Conversely, we would like to make the technologies employed in KIELER available to Ptolemy users as
well. KIELER is composed into modules such that some of them might be used by the Ptolemy community
to enhance the Ptolemy user interface. For example we develop special automatic layout algorithms that
respect port constraints for actor-oriented data-flow diagrams with ports and result more appealing
layouts than standard graph layouters.
We will present the current state of the KIELER pro ject. A focus will be laid on the visualization of
model behavior, e.g. by introduction of a generic simulation engine for different model types. We try to
find a mapping between an arbitrary graphical DSML, such as Statecharts, Matlab/Simulink or SCADE,
to a Ptolemy model. This mapping can hardly be generally applicable to any graphical formalism but
requires precise knowledge of the exact semantics of the graphical language. Hence for each language
this knowledge needs to be provided to the mapping engine prior to the transformation from the DSML
to an equivalent Ptolemy model. We will present the current state of the first approach of creating
formal meta-models for both, the DSML and Ptolemy, and perform the mapping by a model-to-model
transformation with the semantics information provided in form of transformation stylesheets into the
process. Electronic downloads
