Bounded Model Checking (BMC) based on SAT methods consists in searching for a counterexample of a particular length and to generate a propositional formula that is satisfiable iff such a counterexample exists. Our paper shows how the concept of bounded model checking can be extended to deal with \TACTL\ (the universal fragment of \TCTL ) properties of a network of concurrent Timed Automata.

PL

Ograniczona Weryfikacja Modelowa, bzaująca na metodach SAT, polega na poszukiwaniu kontrprzykładów o długości ograniczonej przez pewną liczbę całkowitą k > 0 oraz generowanie formuły zdaniowej, która jest spełniana wtedy i tylko wtedy, gdy taki kontrprzykład istnieje. Celem tej pracy jest przedstawienie koncepcji ograniczonej weryfikacji modelowej dla automatów czasowych reprezentowanych przez siec współbieżnych i wzajemnie komunikujących się komponentów oraz własności wyrażanych w języku logiki TACTL (uniwersalnego fragmentu TCTL).
