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 computer-based method and a computing device for checking stub lengths of via stubs of a printed circuit board (PCB) layout are provided. The computing device displays a check interface, selects signal transmission line from a currently run PCB layout through the check interface, receives a reference stub length input through the check interface, and determines the actual stub length of each via stub of each via each selected signal transmission line connected to. The computing device further determines that a design of one via stub satisfies the design standards, if the actual stub length of the one stub via is less than or equal to the reference length, and determines that a design of one via stub does not satisfy the design standards if the actual stub length of the one via stub is greater than the reference stub length.
