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 computing device and a method selects a signal transmission line from a circuit board, computes an actual length of each line segment of the selected signal transmission line, and computes an actual distance between each line segment of the selected signal transmission line and a corresponding line segment of each neighboring signal transmission line. If each actual length is less than or equal to a corresponding reference length and each actual distance is more than or equal to a corresponding reference distance, the device and method determines a design of the selected signal transmission line satisfies the design standards. Otherwise, if any actual length is more than a corresponding reference length, or if any actual distance is less than a corresponding reference distance, the device and method determines the design of the signal transmission line does not satisfy the design standards.

摘要： A computing device and a method reads a circuit board layout file from a storage device, and selects a first signal transmission line from circuit board layout file as a target line. The computing device and method computes a distance between the target line and the aggressor line corresponding to each unit sample length. If the distance is more than or equal to a height of a sample region, the computing device and method defines the height of the sample region as a crosstalk space between the target line and the aggressor line corresponding to a unit sample length. Otherwise, if the distance is less than the height of the sample region, the computing device and method defines the distance as the crosstalk space between the target line and the aggressor line corresponding to the unit sample length.
