Compositional Model Checking of Real Time Systems
A major problem in applying model checking to finite–state systems is the potential combinatorial explosion of the state space arising from parallel composition. Solutions of this problem have been attempted for practical applications using a variety of techniques. Recent work by Andersen [And95] proposes a very promising compositional model checking technique, which has experimentally been sho...
متن کاملCompositional and Symbolic Model-Checking of Real-Time Systems
In this paper, we present symbolic and compositional techniques to avoid state explosion problems in model-checking for networks of timed automata. The symbolic technique is based on partitioning the inherently in nite state-space of timed automata in terms of simple constraints over the clocks variables instead of into regions. This allows the partitioning to take into account the particular s...
متن کاملCompositional Abstraction in Real-Time Model Checking
The idea to use simulations (or refinements) as a compositional abstraction device is well-known, both in untimed and timed settings, and has already been studied theoretically and practically in many papers during the last three decades. Nevertheless, existing approaches do not handle two fundamental modeling concepts which, for instance, are frequently used in the popular Uppaal model checker...
متن کاملModel Checking Real-Time Systems
This chapter surveys timed automata as a formalism for model checking real-time systems. We begin with introducing the model, as an extension of finite-state automata with real-valued variables for measuring time. We then present the main model-checking results in this framework, and give a hint about some recent extensions (namely weighted timed automata and timed games).
متن کاملSymbolic Model Checking of Real-Time Systems
We present a new real-time temporal logic for the specification and verification of discrete quantitative temporal properties. This logic is an extension of the well-known logic CTL. Its semantics is defined on discrete time transition systems which are in turn interpreted in an abstract manner instead of the usual stuttering interpretation. Hence, our approach directly supports abstractions of...
