Automatic Veri cation of Real { Time Systems ?

Uppaal is a tool suite for automatic veri cation of safety and bounded liveness properties of real-time systems modeled as networks of timed automata. It includes: a graphical interface that supports graphical 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 veri cation of a particular real-time systems fails. The current version of Uppaal is available on the World Wide Web via the Uppaal home page http://www.docs.uu.se/docs/rtmv/uppaal.
