Signal Integrity Analysis and Optimization of Serial Link IBIS-AMI Model
摘要
Abstract
In order to solve the problem of signal integrity caused by the lack of fine configuration of equalizer in high-speed serial link communication,the influence of equalization structure of IBIS-AMI model on signal integrity is studied,and the simulation experiment is established by using Taguchi test method to optimize the equalization parameters,which solves the problem of fine configuration of equalizer parameters.The first-order linear model is established and analyzed,and the eye diagram under the optimal parameter combination is predicted.The simulation value is compared with the predicted value to verify the accuracy of the best parameter combination.Under the optimal equalization parameters,the maximum deviation of the predicted and simulated values obtained by the transmitter and receiver is less than 6％,which proves that the optimal parameter combination is accurate.The degree of eye map expansion is increased by 25％,and the signal quality is obviously improved,which provides better guidance and reference value for the research of system driver setting and signal integrity.关键词
