KarnaughMap 4 (kmap445.exe version 4.4.5) is an educational CAD program that runs on Windows 95/98/ME/NT/2000/XP. It is an interactive Boolean Algebra program extremely easy to use. You enter the specification through the truth table. The moment you click on a cell, the corresponding cell on the Karnaugh map also gets updated. Alternatively, you may enter data into the Karnaugh map directly. If you do so, the truth table will be updated real-time to reflect the Karnaugh map. The program constantly updates the screen, drawing the largest circle around the group of adjacent bits. The output box always displays the prime implicant solution. KarnaughMap is so intuitive that it almost requires no instructions to use. Yet, it contains the following powerful features:The price of kmap 4 is $15.00. You may purchase this with Visa or Master Card. Verification of card takes 1 minute and download takes an additional minute and a half on a 28.8 Kbps modem. kmap445.exe is a self-contained executable that requires no unzipping or installation. It does not install any DLL's to your system because it does not require any special DLL's other than those that are a part of the Windows operating system. kmap445.exe is not copy protected, so you may make copies for yourself, but not for others.

Professor Jack Levine, Department of Electrical and Computer Engineering at Cal State Los Angeles has been using versions of kmap in his Intro to Digital Logic classes for a long time now. He has just begun using kmap 4 and says he is delighted with its new features:
"It is an excellent tool in teaching digital logic, especially in a classroom equipped with computer and projector. In addition to allowing me to enter values in a truth table--including don't-cares--and having these values automatically transferred to a K-map, I can derive an expression from the map in either SOP or POS form. This expression can then be optimized and I can highlight the terms of the simplified expression on the map one by one."
"In the newest version, kmap 4, I can also back-fill the map from a boolean expression and show students how this (1) allows the expression to be simplified if not already in simplest form, and (2) allows the truth table for the expression to be derived in turn from the map."
"Students can also use kmap 4 at home. If they use it properly--i.e. first do their homework problems by hand and then check it with kmap 4--they will gain a great deal of understanding of the value of kmaps. I really recommend this program to anyone teaching digital logic."

Mr. Craig Kief, Lab Director of University of New Mexico Electrical and Computer Engineering Department, has installed Kmap 4 in the EECE 238 lab computers for students to use. Mr. Kief says his students really enjoy Kmap 4 and it fits easily into the course curriculum.
Professor Luiz Antonio Vargas Pinto (ETE Rubens de Faria e Souza), a customer from Brazil who bought my program in 2000, wrote me an email in 2003 saying Kmap 4 had been very helpful in creating a student project involving the design of a highly complex elevator control system.
