Verifying Industrial Hybrid Systems with MathSAT

Gilles Audemard, Marco Bozzano, Alessandro Cimatti, Roberto Sebastiani
2005 Electronical Notes in Theoretical Computer Science  
In this paper, we propose a technique for bounded reachability of linear hybrid automata, based on the reduction of a bounded reachability problem to a MathSAT problem, i.e. satisfiability of a boolean  ...  Unfortunately, continuity of the physical behaviour over time, or triangular constraints, must often be assumed, which yield an undecidable class of hybrid automata.  ...  An example of property to be checked is given by (the negation of) the following formula: This is a typical safety property expressed via the LTL until operator.  ...
