A simple SPICE in C/C++

(C) 2010 Andrew Liu (C) 2010 Stimim Chen

Compile

Tools like lex and yacc are used in parsing, please install flex' and bison'. Simply just `make', tested on 32/64bit GNU/Linux.

Usage

  cspice [NETLIST] [PLOT]

The output format is a gnuplot setting file, using `gnuplot [PLOT]' to plot the output of simulation. For more information of gnuplot, please check the website (http://sourceforge.net/projects/gnuplot/files/gnuplot/4.4.2/).

Support elements and simulations

Support elements
