Problems solved by technology

Due to the large number of wiring on the motherboard, manually checking whether each winding position of the differential line meets the 2S3W rule not only consumes a lot of manpower and financial resources, but is also extremely inefficient and prone to errors and omissions.

Abstract

The invention discloses a wiring detection method and device of a printed circuit board and a computer readable storage medium. The method comprises the following steps: segmenting and extracting alldifferential pair winding line segments in a differential signal line; based on the position information of each line segment in the differential pair winding line segments, determining a plurality oftarget line segment groups located at the protruding positions, for each target line segment group, determining a corresponding first target line segment according to the position information of a preset position on a parallel line segment in the current target line segment group, and determining a second target line segment which is the same differential pair as the first target line segment; calculating the length value of the first target line segment and the vertical distance between the first target line segment and the second target line segment to serve as the winding parameter value of the target line corresponding to the current target line segment group; and judging whether the target wire meets a preset wire winding rule or not based on the wire winding parameter value and thewire winding parameter standard value, therefore, the defects that time and labor are wasted and errors are likely to occur when whether the differential wire wiring rule meets the requirement or notis manually detected in the related technology are overcome.

Description

technical field [0001] The present application relates to the technical field of printed circuit board design, in particular to a method, device and computer-readable storage medium for detecting traces of printed circuit boards. Background technique [0002] With the rapid development of PCB (Printed Circuit Board, printed circuit board or printed circuit board) technology, there are more and more types of PCB board design methods. For example, Cadence, as the most widely used software in the industry, not only has powerful functions and multiple Supported by related software, it also provides an open secondary development interface and a relatively complete development language library, and users can carry out secondary development according to their own needs. The skill language is a high-level programming language based on C language and LISP language built into the Cadence software. Cadence provides a wealth of interactive functions for the skill language. Researching t...
