Compositional Model Checking of Interlocking Systems for Lines with Multiple Stations, Such a system is safety critical and demands thorough formal verification during its development process. Within this context, our work has focused on the extension of a compositional model checking approach to formally verify interlocking system models for lines with multiple stations. The idea of

Modular Model-Checking of a Byzantine Fault-Tolerant Protocol,arly challenging to model-check given their large state spaces and non-determinism. The typical approach to controlling complexity is to construct ad-hoc abstractions of faults, message-passing, and behaviors. However, these abstractions come at the price of divorcing the model from its implementati

A Relational Shape Abstract Domain, compute a description of the input-output relations of programs. In the case of numeric programs, several analyses have been proposed that utilize relational numerical abstract domains to describe relations. On the other hand, designing abstractions for relations over memory states and taking shape

The first originality of our approach is to combine forward and backward static analyses, done by abstract interpretation. The backward analysis computes the minimal precision needed for the inputs and intermediary values in order to have

This paper develops a verification technique to prove correctness of compiler directives combined with functional correctness of the program. We propose syntax and semantics for a simple core language, capturing the main forms of deterministic parallel program

Systematic Predicate Abstraction Using Variable Roles,me of a model checker, or determines if a model checker is able to solve a verification task at all. In this paper we present a method to systematically specify heuristics for generating program-specific abstractions. The heuristics can be used to generate initial abstractions, and to guide abstract
