A Note on Abstract Interpretation Strategies for Hybrid Automata
نویسندگان
چکیده
We report on several abstract interpretation strategies that are designed to improve the performance of HyTech, a symbolic model checker for linear hybrid systems. We (1) simultaneously compute the target region from di erent directions, (2) conservatively approximate the target region by dropping constraints, and (3) iteratively re ne the approximation until su cient precision is obtained. We consider the standard abstract convex-hull operator and a novel abstract extrapolation operator.

Uniformity for the Decidability of Hybrid Automata
We present some new decidability results on the veri cation of hybrid automata by symbolic analysis (abstract interpretation using polyhedra). The results include de ning a class of hybrid automata for which all properties expressed in the real-time temporal logic Tctl are decidable. The obtained class of automata is shown powerful enough to model reactive applications in which every task event...
متن کاملDiscretizing Affine Hybrid Automata with Uncertainty
Over-approximating the set of all reachable states of a given system is an important task for the verification of safety properties. Such an unbounded time verification is in particular challenging for hybrid systems. We recently developed an algorithm that over-approximates the set of all reachable states of a given affine hybrid automata by performing linear template-based abstract interpreta...
متن کاملCounterexample-Guided Refinement of Template Polyhedra
Template polyhedra generalize intervals and octagons to polyhedra whose facets are orthogonal to a given set of arbitrary directions. They have been employed in the abstract interpretation of programs and, with particular success, in the reachability analysis of hybrid automata. While previously, the choice of directions has been left to the user or a heuristic, we present a method for the auto...
متن کاملAnalysis and Verification of Navigation Strategies by Abstract Interpretation of Cellular Automata
We present a new approach to the analysis and verification of simple properties of character navigation. We model navigation strategies for virtual characters by cellular automata, and use standard abstract interpretation techniques for abstracting and verifying navigation properties.
متن کاملExtracting Hybrid Automata from Control Code
Formal methods—and abstract interpretation in particular— can assist in the development of correct control code. However, current approaches to deploying formal methods do not always match the way practicing engineers develop real control code. Engineers tend to think in code first—not formal models. Standard practice is for engineers to develop their control code and then build a model like a ...
