7-variable simplification

  1. Jun 9, 2006 #1
    Assume 7 variables like: C0,C1,C2,C3,C4,C5,C6

    and the output function is : A=C6+C5'C4+C4'C3+C3'C2+C2'C1+C1'C0

    well i know that the simplified function is:


    but i don't know why? and don't know how to simplify such 7-variables function using known algorithms (karnaugh,quinne-mccluskey....)
    i think that it would be more comfortable to use CAD (computer aided design) rather than those algorithms in this case of more than 6 input variables.....

    anyway could anyone guide me through this problem and if i'm right about using CAD , i need to have a clue about it !

    Well, C6 doesn't appear in any terms other than the one that it is in by itself, so you can ignore it initially and add it back in later. This leaves you with a six-variable equation, which is significantly easier to make a Karnaugh map out of.
