SPICE variations

SPICE (simulation program with integrated circuits emphasis) is a powerful computer software program used for rapid simulation and analysis of circuits. It is now an industry standard. Many EDA (electronic design automation) companies offer variations of the basic SPICE -- in most of the cases they are not free. Most of these variations are equipped with a GUI (graphical user interface). There are also SPICE variations which are free. The table below surveys some of the most popular SPICE variations. In this course you'll use Orcad and/or LTSpice, both of which are available in the computer-cluster room.
