ngspice 26

An Open Source CLI circuit simulator tool derived from the Berkeley's spice 3f4(5)
Ngspice is an open source command-line software written in C and designed as a mixed-signal and mixed-level circuit simulator originally based on the Spice3f5, Xspice and Ciber1b1 circuit simulators.

The application’s main goal is to improve the Spice3f5 circuit simulator, as well as to support as many operating systems as possible. In addition, Ngspice adds many new features, enhancements and bug fixes to the original code of the circuit simulators that is based on.

Ngspice is a cross-platform software that has been successfully tested on the Linux, BSD, Solaris, Microsoft Windows and Mac OS X operating systems.
