  • Editorial: automated compositional verification

    Publication Year: 2010, Page(s):179 - 180

    Compositional verification presents a divide-and-conquer, thus more scalable approach to verification: it decomposes the verification task for a system into simpler verification problems for individual components of the system. In checking components in isolation, one typically needs to include information about the contexts/environments in which components are expected to operate. Although compos... View full abstract»

  • Compositional verification for component-based systems and application

    Publication Year: 2010, Page(s):181 - 193

    The authors present a compositional method for the verification of component-based systems described in a subset of the behaviour-interaction-priority language encompassing multi-party interaction without data transfer. The method is based on the use of two kinds of invariants. Component invariants are over-approximations of components' reachability sets. Interaction invariants are global constrai...

  • Environment generation for validating event-driven software using model checking

    Publication Year: 2010, Page(s):194 - 209
    Cited by:  Patents (3)

    Event-driven systems maintain an ongoing dialog with their environment. Examples include: distributed programs, where each process reacts to received messages by performing computation and sending messages to peers; graphical user interfaces (GUI), where the interface software and the underlying application react to user inputs and web-based applications, where presentation, business logic and sto...

  • Assume-guarantee verification of software components in SOFA 2 framework

    Publication Year: 2010, Page(s):210 - 211
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (599 KB)

    A key problem in compositional model checking of software systems is that typical model checkers accept only closed systems (runnable programs) and therefore a component cannot be model-checked directly. A typical solution is to create an artificial environment for the component such that its composition forms a runnable program that can be model-checked. Although it is possible to create a univer...

  • Synthesising certificates in networks of timed automata

    Publication Year: 2010, Page(s):222 - 235

    The authors present an automatic method for the synthesis of certificates for components in embedded real-time systems. A certificate is a small homomorphic abstraction that can transparently replace the component during model checking: if the verification with the certificate succeeds, then the component is guaranteed to be correct; if the verification with the certificate fails, then the compone...
