Abstract
This report describes the techniques used to obtain two three-variable universal logic blocks from NAND circuits. The emphasis for one of these ULB's is on minimizing NAND blocks; for the other ULB, it is on minimizing input pins. The techniques used for the three variable ULB realization are extended to handle realization of a four-variable ULB. Possible compromises to be made in the ULB approach to logic design, and a proposed system application of the ULB, are also discussed.Keywords
