Method and system for processing restricted area of ​​circuit board wiring

Abstract

A method and system for processing a restricted area of ​​circuit board wiring. In the process of designing a circuit board, the first design rule check is performed on the circuit board wiring diagram, and the position of the wiring diagram object that does not meet the first design rule is marked as high Highlight the pattern; provide a setting interface to set the first constrained area to surround the highlighted pattern; obtain the boundary coordinates of the highlighted pattern in the first constrained area, and generate the second constrained area accordingly; finally set The plurality of objects included in the second constraint area respectively have the second design rule attribute, and the highlighting of the highlighting pattern is eliminated. Accordingly, the purpose of precisely setting the restricted area to reduce interference to other signal lines can be achieved, thereby improving the quality and efficiency of circuit board wiring.

Description

technical field [0001] The invention relates to a method and system for processing a restricted area of ​​circuit board wiring, in particular to a method and a system for processing a restricted area of ​​circuit board wiring that executes design rule checks on circuit board wiring files and sets the restricted area. Background technique [0002] In the entire information, communication and consumer electronics products, the printed circuit board (Printed Circuit Board, PCB) is an indispensable basic component. The printed circuit board can connect the electronic parts together and provide the mutual current connection of each electronic part. , and as electronic equipment becomes more and more complex, more and more parts need to be installed on the circuit board, and the lines on the circuit board tend to be denser, therefore, great challenges arise in circuit board wiring. [0003] At present, the more common method of circuit board layout (Layout) is the combination of s...

[0006] However, in the prior art, once the restricted area is set, all the wiring layers from the top to the bottom of the circuit board will be set as this restricted area. In this way, the following effects will be produced: within the same wiring layer, the restricted All the lines in the area are affected by the restricted area, that is, even the lines that meet the design specifications may be modified together, resulting in poor line signal transmission and a decline in the quality of the circuit board

In the same way, because the restricted area runs through all the wiring layers of the circuit board from top to bottom, it also interferes with the lines in other wiring layers, which will also lead to poor signal transmission of the lines and degradation of the quality of the circuit board.

[0007] To sum up, how to overcome the defects of the above-mentioned prior art, and then provide a method and system for processing the restricted area of ​​circuit board wiring, so as to set the restricted area for the position that does not meet the design rules when checking the circuit board design rules , to avoid that the range of the set restricted area cannot accurately cover objects that do not conform to the design rules of the circuit board or the range is too large, so that the wiring of each layer of the circuit board is affected by the restricted area, resulting in signal interference on each layer and a decrease in the quality of the circuit board has become an urgent problem to be solved
