Abstract:
1. A computerized method for inspecting layout of a printed circuit board (PCB) using a computing device, the method comprising: determining, by using the computing device, a component to be checked from an electronic layout diagram of the PCB; selecting a power transmission line of the PCB from the electronic layout diagram; determining whether the component is connected to the power transmission line on the electronic layout diagram; determining whether more than one ground pin of the component is connected to the power transmission line on the electronic layout diagram, when the component is determined to be connected to the power transmission line; determining vias of the PCB that are shared by two or more ground pins of the component on the electronic layout diagram, when more than one ground pin of the component is connected to the power transmission line; marking the shared vias on the electronic layout diagram of the PCB; and wherein the component is determined by: receiving one or more keywords of the component input from a user interface of the computing device; searching components of the PCB for inclusion in the keywords from the electronic layout diagram; and determining the component to be checked according to user selection from the searched components.
