GnuCAP (Gnu Circuit Analysis Package) is a general purpose mixed analog and digital circuit simulator. It performs;

It is fully interactive and command driven. It can also be run in batch mode. The output is produced as it simulates. Spice compatible models for the MOSFET (levels 1-7) and diode are included. This project is not based on Berkeley Spice, but some of the models have been derived from the Berkeley models. GnuCAP is separately developed/maintained tools but associated with gEDA. There are, also, some package which contains the complete Berkeley simulator BSIM (there are no modifications to any of the BSIM code), Jspice a simulator for superconductor and semiconductor circuits (it is incorporated with the Josephson junction model) and a package with the complete set of models from NGSpice (version 17 at the moment).
