    摘要: A computer-based method and a computing device for checking signal transmission lines of a printed circuit board (PCB) layout are provided. The computing device identifies differential pairs in a currently run PCB layout according to an information file for the currently run PCB layout, checks whether any signal transmission line is routed between switching vias of each differential pair according to the information file for the currently run PCB layout, and displays a routing error window to display information of each misrouted signal transmission line.

    摘要: In a method for checking layout of a printed circuit board (PCB) using an electronic device, a signal line is selected from a layout diagram of the PCB. The method searches for signal lines which have an acute angle when deviating from a straight line in the layout diagram of the PCB. The method further locates attribute data of the searched signal lines in the layout diagram of the PCB, and displays the attribute data of the searched signal lines on a display device of the electronic device.
