## 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

Resistor, Inductor, Capacitor, Voltage Control Current Source, Voltage source input, Current source input

### Support simulations

Transient response, Frequency response
