Pin routing inspection method of differential line and related device

Abstract

The invention discloses a pin routing inspection method of a differential line. The pin routing inspection method comprises the following steps: acquiring a to-be-inspected signal line; calculating aninspection distance according to the medium thickness in the laminated structure of the to-be-inspected signal line; constructing an inspection area by taking the to-be-inspected signal line as a center line according to the inspection distance; judging whether a differential signal line exists in the inspection area or not; and if so, taking the differential signal line as a crosstalk differential signal line. The inspection distance is calculated through the obtained medium thickness in the laminating mechanism corresponding to the to-be-inspected signal line. The detection distance and thesignal line are used as the center line to construct the detection area. Finally, the differential line in the detection area is detected, thereby achieving the automatic detection of the differential line, improving the detection efficiency, and maintaining the detection precision and accuracy. The invention further discloses a pin routing inspection device of the differential line, computer equipment and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method for inspecting pin routing of differential lines, a device for inspecting pin routing, computer equipment, and a computer-readable storage medium. Background technique [0002] At present, in the field of chip design, the pins of the chip are usually designed and checked in advance by using calculation software. Generally, there are a large number of pins in a chip, and some of the pins are reserved, and the routing of the reserved pins may affect the signals of normal high-speed differential routing. For example, if a reserved pin is adjacent to a pair of high-speed differential signal line pins and they go out in the same direction at the same time, then the noise introduced by the signal line pair pulled out from the reserved pin will cause the two differential lines to feel inconsistent. That is, the crosstalk felt by one of the differential lines a...

At present, in the prior art, the PCB board is still inspected manually

However, there are many traces in the general PCB. Manual inspection of the reserved pin traces in the PCB not only requires a lot of labor and time costs, reduces efficiency, but also cannot avoid omissions and errors in manual inspections, reducing accuracy and Accuracy
