Abstract

The µZ tool is a scalable, efficient engine for fixed points with constraints. It supports high-level declarative fixed point constraints over a combination of built-in and plugin domains. The built-in domains include formulas presented to the SMT solver Z3 and domains known from abstract interpretation. We present the interface to µZ, a number of the domains, and a set of examples illustrating the use of µZ.
