Crosstalk Analysis of the Same Layer and Inter Layer Based on ANSYS
In miniaturized and high-density PCB design,the problem of intra-layer crosstalk and inter-layer crosstalk on signal integrity is increasing,the transmission line crosstalk model is extracted in the paper,and the crosstalk principle is analyzed based on the mutual capacity and mutual inductance of transmission lines.On this basis,the signal intra-layer crosstalk and inter-layer crosstalk modeling with the same coupling length and the same line spacing are carried out.Finally,ANSYS software is used to conduct crosstalk simulation analysis.Through the simulation results,it can be seen that the inter-layer crosstalk intensity is obviously greater than that of intra-layer crosstalk,so it is necessary to avoid the overlapping of adjacent layers in PCB design to reduce the crosstalk inten-sity of signals.
