Problems solved by technology

[0002] In the process of new projects or revisions, designers often encounter: In order to consider signal quality or processing costs, customers usually use signal lines to be changed to different layers or change the stacking method, so there will be routing changes and The tedious work of line width adjustment
Designers spend a lot of time changing layers and adjusting line widths. Since they are all manual operations, it is easy to miss some signal lines that have not been changed in line width, and it is difficult to find out.

Embodiment

[0014] (1) Layer change and line width adjustment operation under the same stack: Change the line width of ART03 layer to ART07 layer, and the line width of 4.2mil becomes 4mil, and the line width of 3.5mil becomes 3mil. Such as figure 1 As shown, the specific operation is as follows

[0015] A: First execute Export->Sub-Drawing to export all the lines of ART03, and generate the file standard.clp.

[0016] B: Open the standard.clp file with a text editor, use the replace function to replace all ART03 with ART07, replace all 4.200000 and 3.500000 in the standard.clp file with 4.000000 and 3.000000, and finally save the file.

[0017] C: Execute Import->Sub-Drawing in the Allegro software to import the standard.clp file saved in the previous step. At this time, all the lines of ART03 are changed to ART07, and the line widths are all adjusted.

[0018] (2) Change the wiring layer and adjust the line width after the stack changes: Change the 6-layer board to the 8-layer board: ...

Abstract

The invention discloses a wire layer exchange and wire width adjustment method based on Allegro software. The method includes the steps: exporting a clp file of a wire by the aid of a Sub-Drawing instruction in the Allegro software; amending the clp file to achieve wire layer exchange and wire width adjustment. According to the method, parameters (wire layer and wire width) are replaced on the clpfile and then imported into a target PCB (printed circuit board) file, so that wire width adjustment and wire layer exchange can be achieve. Compared with manual operation, operation difficulty is greatly reduced, accuracy is improved, operation time is shortened, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of circuit board layout design, in particular to a method for changing layers of wiring and adjusting line width based on Allegro software. Background technique [0002] In the process of new projects or revisions, designers often encounter: In order to consider signal quality or processing costs, customers usually use signal lines to be changed to different layers or change the stacking method, so there will be routing changes and The tedious work of line width adjustment. Designers spend a lot of time changing layers and adjusting line widths. Since they are all manual operations, it is easy to miss some signal lines that have not been changed in line width, and it is difficult to find. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a method for routing layer change and line width adjustment based on Allegro...
