NER: NanoCAD - Computer-Aided Design Algorithms and Tools for Nanotechnologies

提案编号：303789标题：NER：NanoCAD-用于纳米技术的计算机辅助设计算法和工具近年来在纳米电子器件设计和制造领域出现了巨大的研究活动。这种“纳米器件”包括固态量子效应器件和分子器件。就逻辑和体系结构层面的工作而言，基于量子点单元的量子细胞自动机(QCA)和基于共振调谐二极管(RTD)的实现似乎领先于其他实现，基于这些器件的芯片很可能在本十年内成为可能。虽然已经为各种纳米技术展示了工作装置和逻辑门，甚至一些小电路，但还没有发展出用于在这些技术中自动合成大型逻辑电路的逻辑综合方法。这项提议的目的是开发自动逻辑综合算法，并将其作为软件工具来实现，以弥补这一差距。在这个探索性的研究阶段，我们将以基于QCA和RTD的逻辑电路为目标，具体地，我们将开发一个通用的多电平逻辑综合算法和软件工具，使用门限门和多数门作为原始门。我们将派生不同算术单元的位级流水线版本，以利用纳米流水线的概念。我们还将推导出QCA的物理合成规则，以确保其正确的功能。这项研究中开发的软件工具将在万维网上提供，以便广泛传播。这些材料将包括在一门新的研究生水平课程中，课程内容是新兴纳米技术的计算机辅助设计。本科生也将参与这项研究。普林斯顿大学鼓励女性和少数族裔学生通过特别奖学金提出申请。我们将特别欢迎这样的学生加入这项研究。

Proposal No: 303789Title: NER: NanoCAD - Computer-Aided Design Algorithms and Tools forNanotechnologiesThere has been a huge surge of research activity in recent years in the areaof nanoelectronic device design and fabrication. Such ``nanodevices'' include solid-state quantum-effect devices and molecular devices. In terms of work at the logic and architecture levels, quantum cellular automata (QCA) based on quantum dot cells, and resonant tunelling diode (RTD) based implementations seem ahead of others, and chips based on these devices are likely to be feasible within this decade. While working devices and logic gates, and even some small circuits, have been demonstrated for various nanotechnologies, no logic synthesis methodology has evolved yet for automatically synthesizing large logic circuits in these technologies. The aim of this proposal is to develop automatic logic synthesis algorithms and implement them as software tools to bridge this gap. In this exploratory phase of research, we will target QCA and RTD based logic circuits.Specifically, we will develop a general multi-level logic synthesisalgorithm and software tool using threshold gates and majority gatesas primitive gates. We will derive bit-level pipelined versions of different arithmetic units to exploit the concept of nanopipelining. We will also derive physical synthesis rules for QCA to ensure its correctfunctionality. The software tools developed in this research will be made available on theworld-wide web for wide dissemination. The material will be included in a new graduate-level course on Computer-Aided Design for Emerging Nanotechnologies. Undergraduates will also be involved in this research. Princeton encourages applications from women and minority students through special fellowships. Such students will be specially welcome to join this research.
