** About NGSpice

Ngspice is a mixed-level/mixed-signal circuit simulator. Its code is
based on three open source software packages: Spice3f5, Cider1b1 and
Xspice. Ngspice is part of gEDA project, a full GPL'd suite of
Electronic Design Automation tools.

Spice3 does not need any introduction, is the most popular circuit
simulator. In over 30 years of its life Spice3 has become a de-facto
standard for simulating circuits.

Cider couples Spice3f5 circuit level simulator to DSIM device
simulator to provide greater simulation accuracy of critical
devices. DSIM devices are described in terms of their structures and
materials.

Xspice is an extension to Spice3C1 that provides code modeling support
and simulation of digital components through an embedded event driven
algorithm.
