NMLib: A Nanomagnetic Logic Standard Cell Library

Abstract

The Nanomagnetic Logic (NML) is a promising new technology that can build low-power devices at room temperature. Furthermore, this technology allows mixing logic and memory on the same device. The creation of Electronic Design Automation (EDA) tools and flows is an essential step towards developing NML for integrated designs. There is plenty of room for creating new EDA methodologies for this kind of emerging nanotechnologies since the scarce number of works in this field. Standard cells is an important step in this context since they strongly relate to the routing and placement algorithms. This work presents NMLib, an NML cell library developed for the NMLSim 2.0 simulator. In contrast to CMOS, the NML features require logic cells and interconnection cells, since all circuit is developed using the same building block. Moreover, we present a full-adder, and a ripple carry adder circuit designs using NMLib to demonstrate NMLib feasibility.

Design Automation for Emerging Technologies

“…Because of the challenges of building NML circuits, the considerable dependence on the particle's geometry and their positions, and the complexity of organizing the magnets into clock zones to guide the signal propagation properly, [57] proposed a library of NML standard cell libraries to develop NML circuits. The library was developed on the NMLSim and presented a design protocol to make the designer's life easier during the physical mapping.…”

A Model for the Evaluation of Monostable Molecule Signal Energy in Molecular Field-Coupled Nanocomputing

“…The model computes the signal energy without the need for computationally expensive ab initio calculations. This enables the model to be easily integrated into CAD and simulation tools [18,19], which are gaining more and more importance in the field of FCN design [8,18,[20][21][22][23][24], enabling the analysis of signal energy in large circuits with considerable accuracy and without strongly impacting the demand of computational resources, thus favoring the design of future molecular FCN devices. The proposed model is generic and can be applied to any molecule provided it is monostable.…”
