摘要：
A system and method for checking a ground via of control chips of a printed circuit board (PCB) provides a graphical user interface (GUI) displaying a layout of the PCB. The control chip has a plurality of ground pins. The computer searches for signal path routing of each ground pin and ground vias along each signal path routing of each ground pin. If there are any ground vias having the same absolute coordinates, the computer determines that the ground vias are shared by more than one ground pin.
