VERDICT-a tool for model-based verification of real-time logic process controllers

This paper provides an overview of a project in which a practically applicable tool for the algorithmic formal verification of logic controllers (including timers) for processes with at least piecewise continuous dynamics is developed. In contrast to existing verification techniques from computer science, the presented approach is based on a model of the uncontrolled plant. Condition/event systems are used as the underlying modeling framework. They provide the possibility to build discrete, real-time, and modular models. The paper presents the basic tool architecture and discusses the current project status.
