T-type topology line length inspecting method, device, apparatus, and readable storage medium

Abstract

The invention discloses a PCB-based T-type topology structure line length inspecting method, which comprises the following steps: determining a signal line of the T-type topology structure to be checked; Determining a backbone length and a branch length corresponding to the signal line; Using preset line length inspection rules, inspecting the backbone length and branch length of the signal line to determine signal lines that do not meet the line length inspection rules. As can be seen, in this technical scheme, After determining the backbone length and branch length of the signal line, The signal lines which do not meet the requirements can be automatically screened out through the preset line length inspection rules. The method of automatically inspecting whether the T-shaped topology wiring of the PCB meets the requirements can reduce a large number of working hours, shorten the development cycle, avoid detection missing, and has wide application range and high popularity. The invention also discloses a PCB-based T-type topology structure line length inspecting device, an apparatus and a readable storage medium, which can also realize the technical effect.

Description

technical field [0001] The present invention relates to the technical field of PCB thread arrangement, and more specifically, relates to a method, device, equipment and readable storage medium for checking the length of a PCB-based T-shaped topology structure. Background technique [0002] In PCB (Printed Circuit Board printed circuit board) wiring design, T-type topology is a common wiring structure; see figure 1 , is a schematic diagram of a T-shaped topology structure in the prior art. In this figure, Driver is the transmitter, U2 and U3 are receivers, L1 is the main line, the length of L1 is the length of the main line, and L2 and L3 are two branches. The branch line, the length of L2 and L3 is the branch line length. In the chip design specification, corresponding requirements will be given for the line lengths of L1, L2, and L3, and the equal lengths of L2 & L3. At present, Layout engineers set the wiring rules according to the requirements. To realize this rule sett...

Problems solved by technology

Layout engineers manually control the wiring, so it is inevitable that the wiring does not meet the requirements.

When the project is tight and the number of T-topology wiring is large, checking one by one will consume a lot of time and manpower
