Truth Tables and Karnaugh Maps
(http://en.wikipedia.org/wiki/Karnaugh_map) are the primary tools I
always used when working on things like this.
Don't forget that you can split inputs (signals, wires, copy
variables, whatever you want to call them) and you can use True and
False constants to make a function (gate) that takes two inputs only
require 1.
