Ngspice is a free, open source software package for circuit simulation. It requires a modern computer with a compiler for the C programming language and a UNIX-like environment (Linux, Mac OS X, or Windows with Cygwin). Ngspice requires a minimum of 32 MB RAM and 10 MB of disk space, although more memory and disk space may be necessary for more complex simulations. Ngspice also requires the GNU Readline library, and the optional Gnuplot plotting software.
