Property Specification Patterns (PSPs) have been proposed to solve recurring specification needs, to ease the formalization of requirements, and enable automated verification thereof.

This extension enables us to reason about functional requirements which would not be captured by basic PSPs. We contribute an encoding from constrained PSPs to LTL formulae, and we show experimental results demonstrating that our approach scales on requirements of realistic size generated using a probabilistic model.

Abstract

Property Specification Patterns (PSPs) have been proposed to solve recurring specification needs, to ease the formalization of requirements, and enable automated verification thereof. In this paper, we extend PSPs by considering Boolean as well as atomic numerical assertions. This extension enables us to reason about functional requirements which would not be captured by basic PSPs. We contribute an encoding from constrained PSPs to LTL formulae, and we show experimental results demonstrating that our approach scales on requirements of realistic size generated using a probabilistic model. Finally, we show that our extension enables us to prove (in)consistency of requirements about an embedded controller for a robotic manipulator.
