Abstract:

In view of the complex high speed signaling channel loss problem,this paper puts forward the PDA (Peak Distortion Analysis) algorithm to evaluate the channel.The impulse response of the superposition method is used to obtain the worst eye diagram and the worst pattern of the high speed signal system.The PDA algorithm is a powerful tool for the analysis of jitters and noise characteristics of the signal chain.Simulation results show the effectiveness of the algorithm which achieves fast,efficient and accurate calculation of the worst-case eye diagram and pattern of the system.
