Automatic Verification of Real–Time Systems

Uppaal is a tool suite for automatic veriication of safety and bounded liveness properties of real-time systems modeled as networks of timed automata. It includes: a graphical interface that supports graphi-cal and textual representations of networks of timed automata, and automatic transformation from graphical representations to textual format, a compiler that transforms a certain class of linear hybrid systems to networks of timed automata, and a model{checker which is implemented based on constraint{solving techniques. Uppaal also supports diagnostic model-checking providing diagnostic information in case veriication of a particular real-time systems fails.
