Abstract:
1. A method being executed by a processor of a computing device for checking design of a printed circuit board (PCB) layout file, the method comprising: reading the PCB layout file from a storage device by using the processor, wherein the PCB layout file comprises arrangement information of signal lines, power lines, and power through-holes of a PCB; receiving a reference distance by using the processor, the reference distance according to a distance between a selected power through-hole of the PCB and a neighboring signal line that neighbors the power through-hole of the PCB; determining whether the design of the PCB layout file needs to be amended by searching one or more line segments of one or more signal lines by using the processor, wherein a distance between each of the one or more line segment and the selected power through-hole is less than the reference distance, and the selected power through hole is selected according to steps of: searching all power lines in the PCB layout file, and displaying names of the power lines in a first region of a user interface displayed on a display device, selecting a power line from the first region,and searching power through-holes that the selected power line passes through in the PCB layout file, and displaying names of the power through-holes in the first region, the names of the power through hole including a name of the selected through-hole; and determining that the design of the PCB layout file needs to be amended in response that the one or more line segments have been searched.
