Abstract

Formal verification by means of model checking avails in discovering design issues of safety systems at the early stages. However, a significant amount of time and effort is required to decipher its results and localize the failure, especially in complex logic. This work continues our previous study on the visual explanation of failure traces and introduces change-based causes. Additionally, inspired by the types of properties that revealed model failures in projects of VTT in the Finnish nuclear industry, we define a new form of explanation – a hybrid influence graph. The new approach was implemented in a tool called Oeritte and evaluated using two practical examples of failures in nuclear instrumentation and control systems.
