Development of interactive digital MSI circuit model via Microsoft Excel

Abstract

This paper describes how a spreadsheet application (Microsoft Excel) can be used to model a 74LS83 (4-bit parallel binary adder) Medium Scale Integration (MSI) circuit operation. Using a spreadsheet application rather than conventional simulation software has several advantages in term of cost and the portability of the model between applications especially for the Microsoft Office Family application such as PowerPoint which were used commonly for teaching purposes. It can also be integrated into a webpage for self learning purposes [1].
