In this thesis, we propose an algorithm for merging the simultaneous switching behavior on a general bus. First of all, we find there is indeed data dependency on data bus. Due to the Miller Effect considering data dependency, we minimize the coupling capacitance induced between adjacent wires. By analyzing the data transmitted on data bus, we reduce the numbers of the worst case of the switching patterns through wire reordering. Experimental results demonstrate that we can achieve 5% improvements on average in the bin files, 4.3% in the .pdf files, and 20% in the .txt files.Acknowledgements ii 摘要 iii Abstract iv Content v List of Tables vi List of Figures vii Chapter 1 Introduction 1 1.1 Motivation 1 1.2 Our Contribution 5 1.3 Organization of the Thesis 7 Chapter 2 Preliminaries 8 2.1 Crosstalk Introduction 8 2.2 Bus Model 10 2.3 Miller Effect 12 2.4 Terminology 14 2.5 Related Work on Crosstalk Minimization 15 2.6 Problem Formulation 18 Chapter 3 Algorithm 21 3.1 Algorithm Overview 21 3.2 SoC Architecture 22 3.3 Wrapper Algorithm 24 3.3.1 Objective 24 3.3.2 Total Crosstalk Induced on Bus 25 3.3.3 The Minimum Hamiltonian Path 28 3.4 Further Discussion 31 3.4.1 Data Types 31 3.4.2 Permutation Transmission Mechanism 31 3.4.3 Tradeoff between Overhead and Area 33 Chapter 4 Experimental Results 35 4.1 Results 35 4.2 Justification 48 Chapter 5 Conclusions and Future Work 51 Bibliography 53330331 bytesapplication/pdfen-US資料相依性串訊排線重組data dependentcrosstalkwire permutationthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/57427/1/ntu-96-R94943152-1.pdf
