An approach to model checking for nonlinear analog systems

We present the first approach to model checking for nonlinear analog systems. Based on digital CTL model checking ideas, results in hybrid model checking and special needs in analog verification, a new model checking tool has been implemented Published model checking tools for hybrid systems require discrete or partly linear system descriptions. Our focus is on nonlinear analog behavior, therefore a new approach is necessary. There are mainly two aspects to be considered. Firstly, a discrete model retaining the essential nonlinear analog behavior has to be developed Secondly, model checking for analog systems requires extensions of the language to define analog system properties in a reasonable way.
