First, the number of layer change: it will cause the change of the test plane, so it will cause the discontinuity of the return path. Therefore, the centralized layer change of the signal should be avoided as far as possible, and the cable should not be changed in the same layer, which can minimize the loop area of the number and reduce EMI problems.

Important idea: In a low-speed circuit, the signal flows back along the path with the least resistance; In a high-speed circuit, the signal flows back along the path with the least inductance, rather than the path with the least resistance. The inductance minimum path reflux is manifested in that the return path of the signal is closely under the signal path to minimize the loop area of the signal and reduce the EMI problem.

Second, the loop area: the route taken by the signal must constitute a closed loop, that is, including the signal path and the return path. The area of the signal loop is determined by the signal path and the signal return path. In order to ensure that the loop area of the signal is as small as possible, the parameter plane of the signal should be kept continuous, and the signal change layer should be reduced as much as possible.

Third, the attention of the number of concentrated layer change:

(1) When one GND is changed to another GND after the signal concentration is changed, more GND holes should be carried at the signal concentration is changed, so as to provide the shortest signal return path and reduce the signal loop area.

(2) When a certain GND becomes a POWER after the signal is changed, some decoupling capacitors connected to the GND POWER should be placed in the middle of the signal at the layer change

(0.01uF~0.1uF) to provide the shortest AC signal return path and reduce the signal loop area.

(3) When the signal concentration changes layer, when the reference flat mower POWER changes to mower POWER, more P0WER holes should be carried at the signal concentration change layer to provide the shortest AC signal return path and reduce the signal loop area.
