While these elements enable a great variety of simulation work, users familiar with SPICE in other environments will be used to incorporating models of commercially-available commercially-available semiconductors, integrated circuits and other devices as more complex SPICE models. Indeed, semiconductor manufacturers often freely supply these to help users simulate and develop circuits using
