Dataflow Modeller

The Dataflow Modeller is a multi-platform Graphical User Interface for editing, debugging and analyzing dataflow models. It supports various dataflow formalisms including (Homogeneous) Synchronous Dataflow, Cyclo-Static Dataflow, Boolean Dataflow and Scenario-Aware Dataflow. The Dataflow Modeller can be extended with plugins for Importing, Exporting, Analyzing and Transforming models. The Dataflow Modeller uses the Qt-based C++ libraries to realize deployment on multiple platforms and comes with the GNU Lesser General Public License 3.0.

Plugin Development Kit

The Dataflow Modeller can be extended with your own plugins for Importing, Exporting, Analyzing and Transforming dataflow models. To assist in the development of such plugins, a development kit is available. This development kit includes Qt-based source code for an example plugin, the C++ libraries of the Dataflow Modeller that are required to compile your plugin (including a doxygen configuration to create documentation) and instructions for deployment and installation.
