The Karnaugh Map represents the most useful functionality of the tool. To change the values of the minterms of the function, click on the cells of the map. As the truth table, the alteration of this values is cyclic. After mounting the function, it is possible to do the logical
minimization going to the "Actions" menu, "Find Final
Cover" item or clicking on the
The acquirement of the prime implicants that cover the specified function is done by Quine-McCluskey logical optimization algorithm [Katz 1995], computationally more efficient than the manipulation by Karnaugh Map. Additionally, a window shows text information about the behavior of the algorithm during the optimization process. The resulting equation of the minimization is shown below the map. To visualize the prime implicants (cubes of the solution), just click on the buttons which labels are the own prime implicants, located at the right side of the Karnaugh Map. Other property of the tool is the possibility of changing the order of the variables in the Karnaugh Map. To do so, you must click on one of the boxes located at the upper left corner of the map and select the desired variable. The indices of the minterms showed in each cell are automatically refreshed. |
