Description:
GNU Circuit Analysis package
GNUCAP is a general purpose circuit simulator. It performs nonlinear dc and transient analyses, Fourier analysis, and ac analysis linearized at an operating point. It is fully interactive and command driven. It can also be run in batch mode or as a server. The output is produced as it simulates. Spice compatible models for the MOSFET (level 1,2,3) and diode are included in this release.
