Free uml modeling software for windows

UML StateWizard is a add-in for Visual C++, which provides a UML (Unified Modeling Language) state machine programming mechanism in form of portable standard C or C++ classes for either embedded systems development and simulation, or Windows/WinCE application development.
After embedded systems simulation and debugging in IDE, developer can move program to a destination working environment (such as VxWorks, embedded Linux, etc) with little or no extra investment of effort.
- A ClassWizard-like round-trip UML dynamic modeling/development tool runs in popular IDEs.
- A Cross-platform state-oriented framework for Win32, Linux, pSOS.
- For concurrent,distributed and real-time application development.
UML StateWizard supports:
- Visual C++ 6.0 English and German Edition
- eMbedded Visual C++4.0
- Visual Studio 2003
- Visual Studio 2005 (new)
UML StateWizard is a full-featured UML tool:
- UML diagram support: StateWizard supports the state tree, state chart drawing for dynamicl modeling.
- Forward engineering: The StateWizard UML tool does not limit its use to just pictorial depictions of diagrams. Because the structure of the system defined by the diagram is translated by a developer into actual source code, StateWizard bridges this step by generating the source code in a state machine framework with the methods stubbed out. Developers can take up this stub code and fill in with the actual code.
- Reverse engineering: Reverse engineering is exactly the opposite of forward engineering. In reverse engineering, StateWizard loads all the files of the application/system, identifies state relationships among applications, and reconstructs the entire state machine structure along with all relationships.
- Round-trip engineering: A rule in software design is that no design remains unchanged. This is as true for small systems as it is for large systems. During development, the design structure defined in the UML model undergoes changes to incorporate differences in implementation that may not have been envisaged during design. It becomes very difficult to keep the design of the system synchronized with the changes in the source code. StateWizard?s round-trip engineering feature allows the UML tool to synchronize the model with changes in the application code. StateWizard enforces real-time synchronization of its model to modifications in the source code. For example, developers can visually do a drag-and-drop operation in a state chart diagram and the source code will change as well. On the other hand, developers may directly modify the source code and modifications will be automatically shown in the state chart diagram. StateWizard serves as a bridge between state chart diagram and source code.
- Documentation: StateWizard provides some way for the designer to document design decisions in the diagrams. A designer may save a state chart as a BMP file and a state tree as a text file.
- Integration with popular IDE (VC++): With the increasing use of iterative methodologies for building software systems, it becomes very difficult to keep the design of the system in sync with the developed code. Hence, it would be useful if the UML tool provides integration with popular IDEs. This feature would enable the UML tool to be updated with the changes in the source code made in the IDE.
