DepthK: A k-induction verifier based on invariant inference for C programs

Abstract

DepthK is a software verification tool that employs a proof by induction algorithm that combines k-induction with invariant inference. In order to efficiently and effectively verify and falsify safety properties in C programs, DepthK infers program invariants using polyhedral constraints. Experimental results show that our approach can handle a wide variety of safety properties in several intricate verification tasks.
