Patent ID: 8255866

Claim:
A computer-based method for checking distances between transmission lines and anti-pads arranged on a printed circuit board (PCB), the method comprising: reading a PCB layout file from a storage device of a computing device, wherein the PCB layout file comprises layout information of components arranged on the PCB; selecting one or more transmission lines having the same design standards from the PCB layout file; setting a standard distance between each selected transmission line and each neighboring anti-pad arranged on the PCB; reading a transmission line from the one or more selected transmission lines; determining neighboring anti-pads of the read transmission line, and determining an actual distance between the read transmission line and each neighboring anti-pad; determining that the transmission line and a neighboring anti-pad do not satisfy design requirements, on condition that an actual distance between the read transmission line and the neighboring anti-pad is less than the standard distance; and highlighting the read transmission line and the corresponding anti-pad in the PCB layout file, to prompt a user to modify design of the highlighted transmission line and anti-pad.
