In this contribution we present the first method for model checking on nonlinear analog systems. Based on digital CTL model checking algorithms and results in hybrid model checking, we have developed a concept to adapt these ideas to analog systems. Using an automatic state space subdivision method the continuous state space is transfered into a discrete model. In doing this, the most challenging task is to retain the essential nonlinear behavior of the analog system. To describe analog specification properties, an extension to the CTL language is needed. Two small examples show the properties and advantages of this new method and the capability of the implemented prototype tool.

In this contribution we present a new method for developing discrete models for nonlinear analog systems. Using an adaptive state space intersection method the main nonlinear properties of the analog system can be retained. Consequently, digital model checking ideas can be applied to analog systems. To describe analog specification properties an extension to the standard model checking language CTL and the appropriate, algorithmic modifications are needed. Two nonlinear examples are given to show the feasibility and the advantages of this method.
