Computing device and method for automatically checking wiring information

摘要

In a computing device, a computerized method and a non-transitory storage medium are applied in checking whether the transmission lines in a stored wiring diagram meet a certain criterion in relation to vias in the routes of differential pairs. A transmission line is selected to determine whether or not the line belongs to a differential pair and passes through at least one via. Another transmission line of the differential pair is obtained for analysis when the selected transmission line passes through at least one via. Sizes of vias in the respective routes of the differential pair are compared and a distance between the vias of the differential pair is compared. The differential pair, and the sizes of vias which comply or do not comply with the criterion are recorded and displayed in a list of results.

1. A computerized method for automatically checking wiring information, the method being executed by at least one processor of a computing device, and the method comprising:
selecting a transmission line; determining whether or not the selected transmission line passes through at least one via when the selected transmission line belongs to a differential pair; obtaining another transmission line of the same differential pair when the selected transmission line passes through at least one via; determining whether sizes of vias for the differential pair are the same, and determining whether a distance between the vias for the differential pair complies with a check criterion; recording information of the differential pair into a resulting list when the sizes of the vias are different or the distance between the vias does not comply with the check criterion; and displaying the resulting list on a display unit of the computing device.
