A new methodology for design and simulation of NML circuits

Abstract

Field-Coupled nanocomputing alternatives are promising technologies that can outcome the size/energy limitations of CMOS transistors. Nanomagnet Logic (NML) technology is one of their variations, which incorporates processing and memory using single-domain nanomagnets, operating at room temperature with low energy dissipation. While simple NML logic circuits have been experimentally demonstrated recently, considerable less work has been done on the design and simulation of more complex NML circuits. In this paper, we present a tool for the design and simulation of NML circuits, in which the designer is allowed to manually place the magnets in a grid to construct a desired NML circuit. The outputs from the circuit's logic gates are then calculated using a fast tri-state algorithm.
