Cadence® PSpice® A/D is the de-facto industry-standard Spice-based simulator for system design. It simulates complex mixed-signal designs containing both analog and digital parts, and it supports a wide range of simulation models such as IGBTs, pulse width modulators, DACs, and ADCs. Its built-in mathematical functions and behavioral modeling techniques enable fast and accurate simulation of designs with efficient debugging. PSpice A/D also allows users to design and generate simulation models for transformers and DC inductors.
