摘要： In a method for verifying a printed circuit board (PCB) layout using a computing device, a PCB simulation file is obtained from a storage device of the computing device, and a PCB image is displayed on a display device according to the PCB simulation file. The PCB image includes multiple signal lines and switching voltage regulator nodes (SVRN). A SVRN to be checked is selected from the PCB image, and all signal lines around the SVRN are searched. The method calculates a layout distance between the selected SVRN and each of the searched signal lines, and generates a graphical window interface to position a signal line whose layout distance is equal to or less than the minimum distance. The method further modifies the layout of the positioned signal line to satisfy a layout design specification by increasing the layout distance to the minimum distance.

摘要： A printed circuit board includes a signal layer and a reference layer. The signal layer is covered with copper foil. A circuit topology for multiple loads is set on the signal layer. The circuit topology includes a driving terminal, a first signal receiving terminal, and a second signal receiving terminal. The driving terminal is connected to a node through a first transmission line. The node is connected to the first and second signal receiving terminals respectively through a second and a third transmission lines. A difference between lengths of the second and third transmission lines is greater than a product of a transmission speed and a rise time of signals from the driving terminal. The reference layer is covered with copper foil, and arranged under the signal layer. A region without copper foil is formed on the reference layer, under the second transmission line.
