New for July 2009! And we could surely use some help on this page... Spice is a general purpose analog circuit simulator that is used to predict circuit behavior. Spice is an acronym for simulation program for "integrated circuits emphasis". Spice is to the time domain like linear simulators are to the frequency domain, it can simulate voltage transient behavior, but accuracy is best if you use it below microwave frequencies. Thus in microwave circuits Spice is typically used to simulate rise and fall times of modulator circuits, voltage regulator noise rejection, etc.

History of Spice

Spice was originally developed at the Electronics Research Laboratory of the University of California, Berkeley in 1975.

PSpice is the PC version of Spice.

Spice links

There are a zillion web sites that will give you information on Spice, just google "spice analysis" and you'll see.

Free download

This suggestion came from Fred. Thanks!

QUCS is an open source digital , RF and microwave circuit simulation program that may be of some help to others in the RF field. Its full name is "Quite Universal Circuit Simulator". The great thing is it is FREE and quite powerful. Download it ...... and play with it......there are a large selection of examples available. It has a nice GUI, user friendly, and step by step tutorials. There are Linux, Mac and Windows versions. It's available on sourceforge.

So are many other versions of Spice.
