Electronics Workbench (EWB) is a software simulation tool that is used to reinforce the theory presented in each chapter of the Floyd textbook. It provides an accurate simulation of digital and analog circuit operation along with a simulation of instruments used by a technician to measure IC, component, and circuit characteristics. With this software, you have the ability to build and test most of the circuits presented in this text.

Here is a circuit simulation tutorial linked to Chapter 20 in EWB Version 5.12.

Here is a circuit simulation tutorial linked to Chapter 20 in multiSIM Version 6.2.

The problems at the end of each chapter are based on circuit files found on the CD, which is provided free with the textbook. The 99 circuit files can be found on the CD in the subdirectory called Samples. The problems are based on the circuits and theory presented in the section corresponding to the file name. Before attempting any EWB problem you must thoroughly understand the material presented in that textbook section. The problem definition for each EWB circuit is fully explained in the Description Window that appears in each EWB file.

Note 1: A free demo of Electronics Workbench can be downloaded from:

Note 2: All of the circuit files are compatible with EWB version 5.12 and MultiSIM version 6.2. If you have version 5.0 you can download a free upgrade to version 5.12 from:

Note 3: To get the best view of the circuits, set your computer monitor resolution to 800 x 600 or better. This can be done via display in the control panel.

Note 4: If you have EWB version 5.12 or MultiSIM but don't have the CD that comes with the Floyd text, you can download the following files, which contain samples of these circuit files for evaluation purposes. These files have all been Zipped.
