Verifying dynamic properties of nonlinear mixed-signal circuits via efficient SMT-based techniques

Abstract

The pressing need for the verification of analog and mixed-signal (AMS) designs is driven by increased design complexity and the integration of such circuits into SoCs. However, verification of AMS circuits remains as a significant challenge. We propose a methodology that leverages SMT-based Satisfiability techniques to tackle the challenges arising from the inherent analog and/or hybrid natures of AMS systems. We demonstrate the feasibility and efficacy of the proposed methodology on conservative verification of dynamic properties of nonlinear AMS circuits.
