چکیده

We present an algorithm for checking whether an innnite transition system, deened by a graph grammar of a restricted kind, is a model of a formula of the temporal logic CTL. We rst present the syntax and the semantics of CTL, that are deened with respect to transition systems, labelled with atomic propositions. Then, we show how to adapt the formalism of graph grammars, for expressing such innnite transition systems. Our algorithm treats such a nite representation, and modify it, ensuring that the labelling for formulas remains coherent with the truth values of the diierent states of the innnite transition system. Model-checking de CTL sur des structures de Kripke innnies d eenies par des grammaires de graphes simples R esum e : Nous pr esentons un algorithme qui d etermine si un syst eme de transition innni, d eeni par une grammaire de graphes d'un type restreint, est ou non un mod ele d'une formule de la logique temporelle CTL. Nous pr esentons d'abord la syntaxe et la s emantique de CTL, qui sont d eenies suivant des syst emes de transitions etiquet es par des propositions atomiques. Puis, nous montrons comment adapter le formalisme des grammaires de graphes pour exprimer de tels syst emes de transition innnis. Notre algorithme travaille sur ce type de repr esentation nie, et la modiie de mani ere a assurer que l' etiquetage par les formules demeure coh erent avec les valeurs de v erit e des dii erents etats du syst eme de transition innni.

Model Checking on Product Structures

We present an algorithm for checking CTL formulas in Kripke structures with side conditions, where the side conditions define new variables in terms of path formulas. Given any CTL formula where the defined variables may occur, the presented algorithm will determine the set of states where the CTL∗ formula holds that is obtained by replacing each new variable defined by a side condition by its ...

Reducing CTL-live Model Checking to Semantic Entailment in First-Order Logic (Version 1)

The core of temporal logic model checking is the reachability problem, which is not expressible in first-order logic (FOL). Most model checking algorithms, both for finite and infinite Kripke structures, contain a loop that iterates to reach a fixed-point. As a result, reasoners with input languages no more expressive than FOL have been used iteratively for model checking rather than having the...

Applications of Fuzzy Program Graph in Symbolic Checking of Fuzzy Flip-Flops

All practical digital circuits are usually a mixture of combinational and sequential logic. Flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. The concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...
