SPICE simulation in the schematic

Use Simulation to verify circuit designs. SPICE (Simulation Program with Integrated Circuit Emphasis) is a program for the simulation of analog, digital and mixed mode electrical circuits. Operations can include a simple check to make sure all diodes are receiving the current they require based on chosen values, or verifying that the gain and frequency response of an analog amplifier match hand calculations.

Electronics includes a copy of ngspice, an open-source mixed-level/mixed-signal circuit simulator, based on Berkeley spice3f5.

ngspice supports Operating Point, Transient (time), AC (frequency), and DC Analysis types, full digital and mixed-signal simulation modes. You can simulate any valid SPICE circuit, which means all components in your schematic have been mapped to SPICE models, either primitive or model-based.

Electronics comes with a small library of simulation-ready parts called ngspice-simulation, which are library parts that have been pre-mapped to their proper SPICE types, and models have been provided, where applicable. This means you can easily create simulation-ready schematics with these parts. You can also make your own simulation-ready library parts, or setup your parts within an existing schematic, no matter what library they came from.

Digital simulation enables you to simulate digital circuits that make use of digital logic primitive gates, such as AND, OR, and NOT. There are many built-in digital primitives, and Fusion Electronics provides some of these mapped to library parts in the ngspice-digital shared library.
