What is ngspice?
Ngspice is a mixed-level/mixed-signal circuit simulator. Its code is based on three open source software packages: Spice3f5, Cider1b1 and Xspice.
- 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.
