UML State Machine Wizard acts as a Visual C++ Add-in, which provides a UML state machine programming mechanism in portable standard C for embedded systems developing and simulating in Visual C++ developer studio. Just like Visual C++ ClassWizard, UML State Machine Wizard, it runs inside the integrated developing environment. No need to switch between tools for design/development. It can model embedded systems with the State Charts or the State Tree without heavyweight, expensive CASE (computer aided software engineering) tools.
