Abstract
In this article, a verification methodology for mixed-signal Circuits is presented that can easily be integrated into industrial design flows. The proposed verification methodology is based on formal verification methods. A VHDL behavioral description of a mixed-signal circuit is transformed into a discrete model and then verified using well-established tools from formal digital verification. Using the presented methodology, a much higher coverage of the functionality of a mixed-signal circuit can be achieved than with simulation based verification methods. The approach has already been successfully applied to industrial mixed-signal circuits.
