Open-source SPICE circuit simulator for analogue circuits, device models and mixed-signal simulation.
ngspice is an open-source SPICE circuit simulator for simulating analogue, digital and mixed-signal circuits. It suits semiconductor device model validation, I-V curve fitting, circuit prototype verification and teaching, and is often used as the simulation back end for graphical tools such as KiCad and Qucs-S.
Use cases: SPICE, circuit simulation, analogue circuits, device models, I-V curves, mixed-signal simulation
Recommended combination: ngspice + KiCad / Qucs-S
