The best-selling Kmap program since 2001.
Purchase from MyCommerce / Digital River, the most trusted vendor for downloadable software.
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.
