Electronic WorkBench (EWB) is a simulation package for electronic 
circuits. It allows you to design and analyze circuits without using
breadboards, real components or actual instruments. EWB's click-anddrag
operations make editing a circuit fast and easy. You can change 
parameters and circuit components on the fly, which make "what-if"
analysis straight foreward.  

This tutorial is intended as a quick introduction to EWB's basic
features. It first leads you through the fundamental steps of putting a 
circuit together and analyzing its function using the instruments. The
final part of the tutorial consists of two exercises that try to illustrate the
power of EWB. It also tries to encourage you to apply the "what if"
approach to circuit design. It will greatly help your understanding of
electronics if you use EWB in an interactive manner: Make change to the
circuits you are working on, observe the effects that these changes have, 
and try to understand them. EWB puts very little constraints on
parameters so do not be too timid, don't just change things by 10%, try
out what happens when you change them by a couple of orders in

Directly printing EWB schematics and graphs does usually not 
produce satisfactory result, and leads to a tremendous waste of paper.  It
is better to incorporate EWB results by copying them to the clipboard 
using the copy as bitmap command, and then pasting this into a
something like a word document.   To open EWB click on its icon. Initially you will see an empty
circuit window and two toolbars, the circuit toolbar with the common file
management, editing and graphics tools, and a Parts Bin toolbar from 
which you can select a wide range of circuit elements, and instruments.
The following will guide you on your first attempt to simulate circuits.
