Abstract
In 2011, property directed reachability (PDR) was proposed as an efficient algorithm to solve hardware model checking problems. Recent experimentation suggests that it outperforms interpolation-based verification, which had been considered the best known algorithm for this purpose for almost a decade. In this work, we present a generalization of PDR to the theory of quantifier free formulae over bitvectors (QF BV), illustrate the new algorithm with representative examples and provide experimental results obtained from experimentation with a prototype implementation.
