System and method for arranging ground protectionlines in PCB

Abstract

The invention provides a system and method for arranging ground protectionlines in PCB. The method comprises the following steps: selecting to-be-protected signal lines; reading a design specification for signal lines, wherein line widths and safety clearances of the signal lines are defined in the design specification; performing a widening configuration on the line widths and the safety clearances of the signal lines in the design specification; arranging the signal lines according to the design specification and the widening configuration; after completing the signal line arrangement, performing a call-back configuration on the signal lines, and recovering the line widths and the safety clearances of the signal lines; automatically paving ground lines and enabling ground lines to surround the signal lines. Compared with the prior art, the signal lines are arranged after being subjected to a certain feature configuration, and the ground lines are automatically arranged finally, so that the system and the method for arranging the ground protectionlines in the PCB have the advantages that the ground lines can be ensured to surround the signal lines, excellent grounding protection to the signal lines is implemented, the whole line arrangement procedure is automatically completed without reworking and is simple, quick and highly efficient, the plate manufacturing time and the design time can be saved, and the working efficiency of a designer is remarkably improved.

Description

technical field [0001] The invention belongs to the field of printed circuit boards, in particular to a wiring system and a wiring method for ground protection lines in a PCB board. Background technique [0002] With the development of technology, the lines on the PCB are getting thinner and denser. [0003] When designing a PCB, some important signal lines, such as clock lines, radio frequency lines, reset lines, etc., often need to be ground-covered. At present, HDI boards, especially mobile phone motherboards, have a high density and squeeze space, and many important signal lines are routed by the way. There are two ground wires on both sides, in case the ground wire cannot be wrapped after the final board design is completed, but in many cases due to space reasons, the ground wire will be squeezed out during the drawing process of the board, and it needs to be redrawn, even if the ground wire is locked in advance Finally, due to the high density and insufficient space, ...
