[0003] However, in the prior art, if the design method of the above-mentioned scheme is applied, if the distance between any two signal lines arranged on different layers of the PCB is less than a distance critical value, signal interference will also be caused. Therefore, through the current The PCB designed by the design scheme in the technology cannot solve the interference between the signals transmitted on the signal lines set on different layers of the PCB

The embodiment of the invention provides a method and device for detecting design of a PCB (Printed Circuit Board) and the PCB, relating to the technical field of PCB manufacturing and aiming at reducing interference of the PCB among transmission signals of signal wires arranged at different layers. The PCB is of a structure with at least two layers. The method comprises the following steps of: receiving position information of a signal wire to be arranged on any layer of the PCB; determining a critical zone on each layer of the PCB on which the signal wire is arranged according to the position information of the signal wire to be arranged and a distance critical value; if any position information of the arranged signal wire does not exist in the critical zone determined on each layer on which the signal wire is arranged, determining that the signal wire to be arranged is arranged at the right place; and if the position information of any point of the arranged signal wire exists in the critical zone determined on any layer on which the signal wire is arranged, determining that the signal wire to be arranged is arranged at the wrong place, and sending prompt information. The method and device disclosed by the invention is used for detecting the design of the PCB.
Description
technical field [0001] The invention relates to the field of printed circuit board manufacturing, in particular to a method and device for detecting the design of the printed circuit board and the printed circuit board. Background technique [0002] In the existing at least two-layer PCB (Printed Circuit Board, printed circuit board) design, the purpose of signal transmission is achieved by setting signal lines. At the same time, in order to reduce interference between signals and ensure signal integrity, it is usually necessary to Only when the distance value between two adjacent signal lines on the same layer is greater than or equal to the distance threshold value can the design rule be complied with. [0003] However, in the prior art, if the design method of the above-mentioned scheme is applied, if the distance between any two signal lines arranged on different layers of the PCB is less than a distance critical value, signal interference will also be caused. Therefore,...
