COMPUTING DEVICE AND METHOD OF CHECKING WIRING DIAGRAMS OF PCB

摘要

In a method for checking a wiring diagram in a printed circuit board (PCB) design, a pair of differential signal lines in a PCB file is located according to a designation of a user. Components connected by the differential signal lines and vias which the differential signal lines pass through are obtained from the PCB file. A determination of whether obtained components and the obtained vias meet predetermined requirements is made by checking whether copper foils between each pair of the obtained vias or between pins of the obtained components in ground layers and power layers of the PCB file are hollowed.
