| Abstract: | Such signal integrity(SI) issue as timing,reflection,crosstalk,ringing in high speed PCB design is discussed.The simulation and analysis of a PCB of AD/DAC module with the sampling rate of 125MHz are given by using SPECCTRAQuest and Sigxp from CADENCE.The placement and routing in high speed PCB are controled by proper constraints according to the result of pre-route and post-route simulation.The signal integrity of high speed circuit is assured in all steps. |
