SPIN 2014 Talk: SpinCause: A Tool for Causality Checking

Today I talked at the SPIN 2014 symposium in San Jose, CA about the SpinCause tool. The slides for my talk are available here. In this paper we present the SpinCause tool for causality checking of Promela and PRISM models. We give an overview of the capabilities of SpinCause and briefly sketch how the causality checking …

AVM 2013 Talk: Recent Advances in Causality Checking

On Tuesday May 28th 2013 I gave a talk at the Alpine Verification Meeting in Trento Italy with the title “Recent Advances in Causality Checking”.  Abstract: In recent work on the safety analysis of systems we have shown how causal relationships amongst events can be algorithmically inferred from probabilistic counterexamples and subsequently be mapped to fault …

CausCheck : Causality Checking for Complex System Models

I’m currently developing a new method for automated safety analysis of complex systems. This method is called Causality Checking and allows for the automated generation of fault trees out of system or software architectures in SysML or UML. This post gives an overview of how Causality Checking works. CausCheck : Causality Checking for Complex System Models …
