FUNCODE: Effective Device-to-System Analysis of Field-Coupled Nanocomputing Circuit Designs

摘要

Many beyond-CMOS technologies, based on different switching mechanisms, are arising. Field-coupled technologies are the most promising as they can guarantee an extremely low-power consumption and combine logic and memory into the same device. However, circuit-level explorations, like layout verification and analysis of the circuit performance, considering the constraints of the target technology, cannot be done using existing tools. Here, we propose a methodology to take on this challenge. We present function and connection detection (FUNCODE), an algorithm that can detect element connections, functions, and errors of custom layouts and generate its corresponding very high-speed integrated circuits hardware description language netlist. It is proposed for in-plane and perpendicular nanomagnetic logic as a case study. FUNCODE netlists, which take into account the physical behavior of the technology, were verified using circuits with increasing complexity, from 6 up to 1400 gates with a number of layout elements varying from 200 to 2.3e6.
