Meaning of kmapThe Karnaugh map, also known as a Veitch

diagram (KV-map or K-map for short), is a method to simplify Boolean algebra expressions. In a Karnaugh map the map method provides a simple straight forward proc for minimizing Boolean functions.

The kmap method-pictorial form of truth tableThe boolean function is recognised graphically in

the mapMap presents visual diagram of all possible ways

of function

Applications of kmap

Karnaugh Maps are used for many small design problems. It's true that many larger designs are done using computer implementations of different algorithms. However designs with a small number of variables occur frequently in interface problems and that makes learning Karnaugh Maps worthwhile. In addition, if you study Karnaugh Maps you will gain a great deal of insight into digital logic circuits.

conclusion

K-map simplification project is very helpful in simplification of various minterms. One can understand how draw K-map and to solve so that required logic gate can be drawn.

Future enhancementThis project can be enhanced with the following

features :

Here we have only used 16 cells K-map, instead of that we use 32cells,64 cells and so on.

We have ignored the non essential prime implicant to minimize the complexity

Other gates such as NOT, NAND, NOR, XOR, XNOR.
