KARMA HELP


Karnaugh Map

The Karnaugh Map appears at the center of the screen.

You can interact with it by clicking on the minterms (cells) to define a function. Each time you click on a cell the value is changed. The possible values are zero, one and dont-care.

You can also change the order of the variables by clicking on the boxes above the map. When you change the order the map is updated to reflect the new order.


Truth Table

The Truth Table appears at the left of the screen. You can interact with it by clicking on the outputs to define a function.

All the changes that are done in the truth table update the Karnaugh map and vice-versa.


Minimize

Runs Quine-McCluskey algorithm for the function that is currently defined on the Karnaugh map.


Reset

Resets the function that is defined on the Karnaugh map. This means that the value of all minterms will be set to zero.




Covering Table

Shows the covering table of the function that is currently on the Karnaugh map.

You can click on the primes to see them on the map. Red balls indicate that the prime is essential.

It is possible to save the selected primes in a file. If the selected primes do not cover the function completely then a warning message is displayed.
