چکیده

We give complete mathematial foundations for the method, recently developed by Chou, Mannava, and Park, for verifying safety properties of cache coherence protocols. The method employs a specific form of counterexample-guided abstraction refinement and is originally described on worked-out examples of the German and FLASH protocols. We describe and prove the method at an abstract level, thus establishing its scope and opening the way to its further mechanization.

Invariants for Parameter Abstraction ∗

A new approach to combining invariants computing and guard strengthening methods is presented in the context of parameter abstraction for parameterized model checking of cache coherence protocols. The approach uses a small instance of a parameterized protocol as a ”reference model” to compute candidate invariants. References to a specific node in these candidate invariants are then abstracted a...

Static Guard Analysis in Timed Automata Verification

By definition Timed Automata have an infinite state-space, thus for verification purposes, an exact finite abstraction is required. We propose a locationbased finite zone abstraction, which computes an abstraction based on the relevant guards for a particular state of the model (as opposed to all guards). We show that the location-based zone abstraction is sound and complete with respect to loc...

Strengthened State Transitions for Invariant Verification in Practical Depth-Induction

Bounded Model Checking (BMC) is often able to handle thousands of system variables by encoding the system and its properties via symbolic formulas and using satisfiability (SAT) solvers for verification. To further ease the verification of state invariants, BMC is augmented with a general induction rule called k -induction; however, this sacrifices completeness. Invariant strengthening, a metho...

Verification of Semantically-Enhanced Artifact Systems (Extended Version)

Artifact-Centric systems have emerged in the last years as a suitable framework to model business-relevant entities, by combining their static and dynamic aspects. In particular, the Guard-Stage-Milestone (GSM) approach has been recently proposed to model artifacts and their lifecycle in a declarative way. In this paper, we enhance GSM with a Semantic Layer, constituted by a full-fledged OWL 2 ...
