(LaTeX) Abstract:

This paper deals with the problem of safety verification of non-linear hybrid systems. We start
from a classical method that uses interval arithmetic to check whether trajectories can move
over the boundaries in a rectangular grid. We put this method into an abstraction refinement
framework and improve it by developing an additional refinement step that employs constraint
propagation to add information to the abstraction without introducing new grid elements.
Moreover, the resulting method allows switching conditions, initial states and unsafe states
to be described by complex constraints instead of sets that correspond to grid
elements. Nevertheless, the method can be easily implemented since it is based on a
well-defined set of constraints, on which one can run any constraint propagation based
solver. First tests of such an implementation are promising.
