News:

Spectrum Software has released Micro-Cap 11, the eleventh generation of our SPICE circuit simulator.

For users of previous Micro-Cap versions, check out the new features available in the latest version. For those of you who are new to Micro-Cap, take our features tour to see what Micro-Cap has to offer.

32,000 Part Library

With over 32,000 parts in the latest release of our device model library, you'll be able to quickly find most digital logic parts, and analog parts - like diodes, MOSFETs, BJTs, IGBTs, Opamps, JFETs, magnetic cores, crystals, and SCRs.

Micro-Cap directly uses the SPICE subckt models provided by most electronics manufacturers.

You can also fashion new elements from macros or subcircuits and enhance their power by passing them parameters. These elements can be used in other circuits, extending and focusing Micro-Cap to your area of interest. The ability to pass parameters to macros and subcircuits makes the task of device modeling easier.
