Problems solved by technology

[0004] However, when this method achieves the same impedance value, the line width of the signal line needs to be reduced. When the line width of the signal line is small, it may lead to a high scrapping rate of the board during production by the PCB manufacturer.

Abstract

The invention provides a method and system for determining a signal line reference layer, and the method comprises the steps: setting a line width range of the signal line; determining attribute parameters of a printed circuit board, and setting a wiring layer and a resistance value corresponding to the signal line; according to the attribute parameters, the wiring layer and the resistance value, determining a reference layer when simulated line width of the signal line is in the line width range; when an interval laminating layer being arranged between the wiring layer and the reference layer, and according to the wiring position of the signal line on the wiring layer, performing hollowing operation on at least one interval laminating layer. According to the scheme, the signal line realizing more signal functions in a proper line width can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a method and system for determining a signal line reference layer. Background technique [0002] With the continuous development of big data technology, users have higher and higher requirements for server functions. Therefore, in order to meet user needs, it is necessary to realize as many signal functions as possible within a limited structural space. [0003] In the prior art, when designing a high-density board, the thickness of the PP sheet of the printed circuit board (PCB) is generally reduced, so that the PCB can include more stacked layers in a limited structural space. , so as to realize more signal functions. [0004] However, when this method achieves the same impedance value, the line width of the signal line needs to be reduced. When the line width of the signal line is small, it may cause PCB manufacturers to have a high board scrap rate during product...
