Spice3f5

A general-purpose circuit simulator for nonlinear dc, nonlinear transient and linear ac analysis, based on Berkeley Spice3f, with a Qt front end, BSIM3 and BSIM4 models, and .meas, .step and .optimise.

Getting started

New to SPICE? Start with the introduction and circuit description, then try one of the examples.
Coming from Berkeley Spice3? See what's new.
Running a circuit: open it with File › Load netlist in the Qt window, or run spice circuit.cir; see the spice program.
Looking something up: the commands, the device parameters, or search, at the top of every page.
