MacSpice

Circuit simulation is a way of building and testing virtual models of electronic devices. Simulating a design is usually cheaper and quicker than building a prototype. MacSpice requires a text file description of the circuit as input. This 'netlist' lists components and the nodes they connect to. Users may prepare netlists with a text editor or derive them from a circuit diagram using a third-party schematic-capture application. MacSpice then builds a numerical model of the circuit and analyses
