Abstract :
An environment for SPICE called NECTAR has been developed which aids in convergence and user-interface problems with SPICE by simulating the actions taken by expert users. NECTAR recognizes patterns which cause nonconvergence and provides ways around the problems. NECTAR identifies errors in the SPICE input file and may automatically correct them. It can be used as a circuit design aid and improves the user interface for SPICE simulations. NECTAR belongs to the class of knowledge-based systems and is based on knowledge acquired from expert SPICE users and circuit designers.<>
