【摘要】：隨著傳統(tǒng)CMOS器件的飛速發(fā)展,傳統(tǒng)CMOS器件的尺寸越來越小。在此背景下,傳統(tǒng)FPGA取得了空前的發(fā)展。但同時(shí)一些制約傳統(tǒng)FPGA繼續(xù)飛速發(fā)展的因素慢慢凸顯出來,像量子效應(yīng)、大泄漏電流、高功耗密度、復(fù)雜布線與串?dāng)_等問題。在尋找能夠替代傳統(tǒng)CMOS器件過程中,在上個(gè)世紀(jì)90年代,量子細(xì)胞自動(dòng)機(jī)(Quantum-dot Cellular Automata, QCA)被提出。由于其尺寸小、功耗低、運(yùn)算速度快、易于擴(kuò)展等原因迅速被廣大科研工作者關(guān)注。一些傳統(tǒng)電路中的器件像加法器、減法器、觸發(fā)器等器件；在QCA電路中相繼被實(shí)現(xiàn)。并有科研工作者對(duì)QCA器件的可靠性,容錯(cuò)性做了充分的研究。本文先介紹了傳統(tǒng)CMOS器件、FPGA的發(fā)展并說明了面臨的問題。然后詳細(xì)介紹了QCA電路的基本知識(shí)、時(shí)鐘控制方式、信息傳輸機(jī)制以及設(shè)計(jì)仿真軟件。通過對(duì)QCA電路做了充分的研究,利用QCA電路設(shè)計(jì)仿真軟件QCADesigner,本文設(shè)計(jì)并實(shí)現(xiàn)了基于QCA的全新的雙邊沿JK觸發(fā)器、兩種不同漢明碼編碼／解碼電路、模塊化加法器以及乘法器,并對(duì)它們進(jìn)行了詳細(xì)的分析對(duì)比。通過這些基本的電路器件設(shè)計(jì)與分析,充分展示了QCA電路的性質(zhì)與優(yōu)勢(shì),并總結(jié)了這些電路設(shè)計(jì)對(duì)后續(xù)電路設(shè)計(jì)的作用。最后,本文結(jié)合實(shí)際案例總體分析了設(shè)計(jì)基于QCA的FPGA應(yīng)該遵循的實(shí)現(xiàn)方式,并設(shè)計(jì)了一種全新的路由方式。然后利用該路由策略對(duì)提出的案例進(jìn)行改進(jìn),并取得不錯(cuò)的成果。
[Abstract]:With the rapid development of traditional CMOS devices, the size of traditional CMOS devices is becoming smaller and smaller.In this context, the traditional FPGA has made unprecedented development.But at the same time some factors which restrict the rapid development of traditional FPGA such as quantum effect large leakage current high power density complex wiring and crosstalk etc.Quantum-dot Cellular Automata (QCA) was proposed in the 1990s in order to replace the traditional CMOS devices.Because of its small size, low power consumption, fast operation speed and easy expansion, it has been concerned by many researchers.Some traditional circuits, such as adders, subducers and flip-flops, have been implemented in QCA circuits.The reliability and fault tolerance of QCA devices have been studied by some researchers.This paper first introduces the development of traditional CMOS devices and explains the problems.Then, the basic knowledge of QCA circuit, clock control mode, information transmission mechanism and design of simulation software are introduced in detail.Through the full research of QCA circuit, using the QCA circuit design and simulation software QCA designer, this paper designs and implements a new bilateral JK flip-flop based on QCA, two different hamming code coding / decoding circuits, modular adder and multiplier.They are analyzed and compared in detail.Through the design and analysis of these basic circuit devices, the properties and advantages of QCA circuits are fully demonstrated, and the effect of these circuit designs on the subsequent circuit design is summarized.Finally, this paper analyzes the implementation of FPGA based on QCA, and designs a new routing method.Then the routing strategy is used to improve the proposed case, and good results are obtained.
