Abstract

The way of representing Boolean functions has a great influence on VLSI computation time and memory requirements. The need for analyzing the complexity behavior of different logic representations becomes growing importance. Last few decades the XOR/XNOR gates are fully exploited as a potential candidate for incorporation into the design in addition to the AND and OR gates. This paper discusses the complexity behavior of XOR/XNOR min-terms. We propose a novel method to analyze their effectiveness in Reduced Ordered Binary Decision Diagram (ROBDD) representation. Theoretical and Practical results are reported to underline the efficiency of this approach.
