Starting from a continuous-time, continuous-valued behavioral representation of an analog part in terms of a differential -algebraic equation system, a discrete-time, discrete-valued behavioral model is derived. This kind of model both captures dynamic aspects of the analog behavior and can be implemented using the synthesizable subset of a hardware description language like VHDL. With the help of the proposed approach, the continuous-time, continuous-valued analog parts' behavioral descriptions can be replaced by digital behavioral models leading to a verification-oriented model of the underlying mixed-signal circuit. The resulting model can be formally verified using established methods and tools from formal digital verification.en621conference paper
