ArgoUML is a Java base CASE tool. It can generate C++ code from UML and it is very useful in large scale firmware development.
One project is capturing RTEMS design in ArgoUML. RTEMS is converting some of the RTEMS C++ class into ArgoUML's UML.
If ArgoUML can generate code, another project is to support RTEMS as a run-time.
