Symbolic Register Automatam both symbolic and register automata, with a view on applications that were previously out of reach. We study their properties and provide algorithms for emptiness, inclusion and equivalence checking, together with experimental results.

Microgram

Abstraction Refinement Algorithms for Timed Automatative algorithm where a lazy abstraction approach is adopted, meaning that possibly different abstract domains are assigned to each exploration node; and a?symbolic algorithm where the abstract transition system is encoded with Boolean formulas.

CORE

Automated Hypersafety Verificationithm based on a counterexample-guided refinement loop that simultaneously searches for a reduction and a proof of the correctness for the reduction. We demonstrate that our tool .?is very effective in verifying a diverse array of hypersafety properties for a diverse class of input programs.

Synthesizing Approximate Implementations for Unrealizable Specificationsthe synthesis of approximative implementations from unrealizable specifications. Such implementations may violate the specification in general, but are guaranteed to satisfy the specification on at least a specified portion of the bounded-size lassos. We evaluate the algorithms on different arbiter specifications.

Systematische Probleml?sung in Unternehmen been remarkably more challenging when the automaton has diagonal constraints in guards..In this paper, we propose a new termination mechanism for timed automata with diagonal constraints based on a new simulation relation between zones. Experiments with an implementation of this simulation show significant gains over existing methods.
