Problems solved by technology

However, since the PCB is a multi-layer board structure, in addition to the xy-axis interference of the device on the same wiring layer, there is also interference from different layers in the vertical direction. Therefore, on the PCB, other layers below the sensitive device also need to be isolated. Signal traces pass through to prevent interference

Abstract

The invention discloses a wiring detection method of a PCB (Printed Circuit Board). The wiring detection method comprises the following steps: acquiring a bit number identifier of a sensitive device;detecting bit numbers of all devices on all the design files according to the bit number identifiers to obtain sensitive devices on each design file; acquiring a layout area of the sensitive device onthe design file; and capturing all signal lines in the layout area on each design file through a filter, and marking prompt information for the signal lines and the sensitive devices corresponding tothe layout areas where the signal lines are located. The invention further discloses a corresponding device. According to the method and device, the design stability is improved, the design efficiency is greatly improved, and the design period is shortened.

Description

technical field [0001] The present invention relates to the field of circuit technology, and more specifically, to a method and device for detecting traces of a PCB printed circuit board. Background technique [0002] PCB (Printed Circuit Board, printed circuit board), also known as printed circuit board, is the carrier of electronic components in electronic products and the provider of circuit connections for electronic components. The traditional circuit board adopts the method of printing etching resist to make the circuit and the drawing surface of the circuit, that is, for a complete copper skin surface, the unnecessary part is removed by etching, and the remaining copper skin carries the transmission current ( signal), so it is called a printed circuit board or a printed circuit board. [0003] Since PCB involves a combination of various circuit designs, including clock circuits, logic control circuits, high-speed SerDes, power modules, etc., there must be interferenc...
