Abstract
In a method for inspecting the layout of a printed circuit board (PCB), a component to be checked is determined from an electronic layout diagram of the PCB, and a power transmission line which may be serving that component is selected. The layout diagram is checked to determine whether the component is connected to the power transmission line, and further checked to determine whether more than one ground pins of the component is connected to the power transmission line. Vias that are shared by two or more ground pins of the component are determined if more than one ground pin is connected to the power transmission line. Shared vias are marked on the layout diagram.
