Optimizing Circuits for QCA Routing

Quantum-Dot Cellular Automata (QCA) is a new promising technology with great advantages to integrated circuits like faster speed, low power computation and very small size. QCA technology faces several implementation challenges which are being addressed by recent advances. One of the most difficult challenges related to the process of creating circuits with QCA technology is the routing process. In this paper we redesign some circuits with equivalent logic through simplification of functions in order to analyze the circuit routing, also making a comparison among the circuits.
