The described tool, TANGRAM (Tool for Analysis of Diagrams), performs automatic translation from UML diagrams into timed automata, which can be verified by the UPPAAL model checker. We focus on the CORBA Component Model. We demonstrate the overall process of our approach, from system design to verification, using a simple but real application, used in train control systems. Also, a more complex case study regarding train control systems is described
