GNU Circuit Analysis Package (Gnucap) is a general purpose
circuit simulator
Electronic circuit simulation uses mathematical models to replicate the behavior of an actual electronic device or circuit.
Simulation software allows for the modeling of circuit operation and is an invaluable analysis tool. Due to its highly ac ...
