Consistency of Property Specification Patterns with Boolean and Constrained Numerical Signals

12 Dec 2017  ·  Narizzano Massimo, Pulina Luca, Tacchella Armando, Vuotto Simone ·

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 assertions from a constraint system... This extension enables us to reason about functional requirements which could not be captured by basic PSPs. We contribute an encoding from constrained PSPs to LTL formulas, and we show experimental results demonstrating that our approach scales on requirements of realistic size generated using an artificial probabilistic model. Finally, we show that our extension enables us to prove (in)consistency of requirements about an embedded controller for a robotic manipulator. read more
