[0003] However, at present, the inspection of whether there is a signal line between the layer-changing vias of the differential signal line depends on the manual operation of the wiring personnel. Due to the huge number of signal lines on the circuit board, manual operation is not only time-consuming and laborious, but also easily missed due to the negligence of the wiring personnel. Inspection of some signal lines, which affects the wiring quality of the circuit board

Embodiment Construction
[0013] refer to figure 1 Shown is an application environment diagram of a preferred embodiment of the signal line inspection system 10 of the present invention. The signal line inspection system 10 is applied to a computing device 100 . The computing device 100 also includes a processor 20 , a memory 30 and a display 40 . The memory 30 stores at least one circuit board layout diagram 50 and information files corresponding to each circuit board layout diagram 50 . Each information file records the type information of the signal line in the corresponding circuit board layout diagram 50 , the information of the signal line connected to the via hole, and the information of whether there is a signal line between the via hole and the via hole. The memory 30 also stores programming codes of the signal line inspection system 10 . The memory 30 may be a storage device such as a computer, a smart media card, a secure digital card, or a flash card. The signal line inspection system 1...

The invention provides a checking system and a method of signal lines. The method comprises the steps of extracting difference signal lines from a displayed circuit board wiring diagram; checking whether traveling signal lines exist among layer changing via holes of the difference signal lines; and providing a mistake display interface, and displaying checked information of the signal lines placed among the layering changing via holes of the difference signal lines. The checking system and the method of the signal lines can automatically check whether the traveling signal lines exist among the layer changing via holes of the different signal lines on the circuit board wiring diagram, efficiency is high, and omission ratio is low.
Description
technical field [0001] The invention relates to a circuit inspection system and method, in particular to a signal line inspection system and method for inspecting whether there is wiring between layer-changing via holes of differential signal lines. Background technique [0002] There are many strict design specifications for the layout of the signal lines on the circuit board. One of the most basic design specifications is that no signal lines are routed between the differential signal lines and via holes when the circuit board is designed. [0003] However, at present, the inspection of whether there is a signal line between the layer-changing vias of the differential signal line depends on the manual operation of the wiring personnel. Due to the huge number of signal lines on the circuit board, manual operation is not only time-consuming and laborious, but also easily missed due to the negligence of the wiring personnel. The inspection of some signal lines affects the wir...
