ToPoliNano: Nano-magnet Logic Circuits Design and Simulation

Among the emerging technologies Field-Coupled devices like Quantum dot Cellular Automata are particularly interesting. Of all the practical implementations of this principle NanoMagnet Logic shows many important features, such as a very low power consumption and the feasibility with up-to- date technology. However, its working principle, based on the interaction among neighbor cells, is quite different with respect to CMOS devices behavior. Dedicated design and simulation tools for this technology are necessary to further study this technology, but at the moment there are no such tools available in the scientific scenario. We present here ToPoliNano, a software developed as a design and simulation tool for NanoMagnet Logic, that can be easily adapted to many others emerging technologies, particularly to any kind of Field-Coupled devices. ToPoliNano allows to design circuits following a top-down approach similar to the one used in CMOS and to simulate them using a switch model specifically targeted for high complexity circuits. This tool greatly enhances the ability to analyze, explore and improve the design of Field- Coupled circuits.
