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.

摘要： A computing device and a method reads design standards of signal transmission lines in a printed circuit board (PCB) layout file, and determines a minimum reference length of line segments of the signal transmission lines from the design standards. The device and method then selects a signal transmission line from a circuit board, and computes an actual length of each line segment of the selected signal transmission line. If each actual length is more than or equal to the minimum reference length, the device and method determines length design of the selected signal transmission line satisfies the design standards. Otherwise, if any actual length is less than the minimum reference length, the device and method determines the length design of the signal transmission line does not satisfy the design standards.

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 computing device and a method involves selection of one or more transmission lines from a printed circuit board (PCB) layout file, reading a transmission line from the one or more selected transmission lines, and determining neighboring anti-pads of the read transmission line in the PCB layout file. The computing device and method further determine an actual distance between the read transmission line and a neighboring anti-pad. If the actual distance is less than a preset standard distance, the computing device and method determine that the read transmission line and the neighboring anti-pad do not satisfy design requirements, and highlight the read transmission line and the neighboring anti-pad, to prompt a user to amend design of the read transmission line and the neighboring anti-pad.

摘要： A printed circuit board includes a signal plane and a reference plane. The signal plane includes a pad, a passive element mounted on the pad, and a signal transmission line electrically connected to the passive element via the pad. The reference plane provides a return path for a signal transmitted through the passive element and the signal transmission line. A void is defined in the reference plane corresponding to the passive element, to increase a length of the return path. A length of a first axis, perpendicular to the signal transmission line, of the void satisfies a following equation: W 1 ≈ 8  Wpad + 10  T 0.8  Wtrace + T , wherein Wpad is a width of the pad, Wtrace is a width of the transmission line, T is the height of the pad.
