• Nanomagnetic Logic (NML) is a new technology based on nanomagnets. Logic operations are performed at room temperature through dipolar magnetostatic interactions. The low switching energies involved in the operation of NML circuits in addition to the possibility of higher integration density are remarkable advantages of this technology over CMOS-based systems. Although intense work has been done on the physical behavior of the NML systems, simulation tools for the study of large and complex NML architectures are lacking. In this paper, we present a fast and robust computational tool that allows the design and simulation of complex NML circuits. We developed a new fast simulation engine based on single-domain approximation able to capture both the static and dynamic behaviors of the system. The tool simulates the clock, the magnet influence in between neighbors and the thermal effect on the circuit. Initial results show a good agreement with experimental and micromagnetic simulations works. To the best of our knowledge, this is the first open-source NML simulator available and serves as a complete tool to design and evaluate complex NML circuits.
