Logic Synthesis For Regular Fabric Realized In Quantum Dot Cellular Automata, Marek Perkowski, Alan Mishchenko

Electrical and Computer Engineering Faculty Publications and Presentations

Quantum Dot Cellular Automata are one of the most prospective nano-technologies to build digital circuits. Because of the requirements of only 2 layer wiring and noise avoidance, realizing the circuit in a regular fabrics is even more important for this technology than for classical technologies. In this paper, we propose a regular layout geometry called 3x3 lattice. The main difference of this geometry compared to the known 2x2 lattices is that it allows the cofactors on a level to propagate to three rather than two nodes on the lower level. This gives additional freedom to synthesize compact functional representations. We …
