Xholon

The new Xholon Eclipse plugin is a UML/SysML/FSM
(Finite State Machine) simulation environment. The
plug-in transforms your MagicDraw and Topcased
(UML) model into Java and XML, compiles, and
immediately executes it. It also partially works
with Poseidon, Topcased (SysML), and ArgoUML.
Viewers provide runtime animation of state
machines, sequence diagrams, and timing diagrams.
There is initial support for export of models to
Quantum Event Processor, State Machine Compiler,
and State Chart XML formats. The full Xholon tool
includes all of the above functionality, plus much
more.

UML state machine simulation capabilities have
been extended, including animation, and fork,
join, junction. Additional Agent-Based Modeling
functionality is available. The NetLogo-like
syntax has been enhanced. The architecture is more
flexible and is ready to more fully support
integration of multiple domains. Histograms and
probability distributions are now available. Line
charts update in real-time. Numerous other
modeling, simulation, transformation, and
execution features have been added.

Several new domains are supported, including
turtle geometry with limited NetLogo-like syntax,
1D cellular automata, and simple dynamical systems
with numerical integration. UML state machine
simulation capabilities have been enhanced. Grid
or swarm models can be created in UML. Xholon can
transform MagicDraw 12.0 models. The core library
is compatible with Java ME (MIDP). Each class can
specify which Java class implements it. Numerous
other modeling, simulation, transformation and
execution features have been added.

You can now generate complete executable Xholon applications from UML 2 models. Create your models using a third-party UML 2 tool, such as MagicDraw. A lot of common code has been pushed into superclasses, so it's now less work to create Xholon applications without a UML tool. A UML 2 Port class and IPort interface have been added, as well as a PortInterface class and IPortInterface interface. IPort/Port objects can specify provided and required interfaces.

Additional state machine functionality. JFreeChart charts. A GUI with start, pause, and step capabilities. Many new sample applications, with detailed information on each. Support for ECJ genetic programming.
