Embodiment Construction

[0025] In the embodiment of the present invention, the alignment to be adjusted is determined according to the user's instruction, and the line width to be adjusted is determined according to the obtained characteristic impedance to be adjusted, and the endpoint coordinates of the alignment to be adjusted are read from the board-making file. , redraw the line according to the read endpoint coordinates and the line width to be adjusted, so as to achieve the purpose of automatically adjusting the line width.

[0026] see Figure 1B , the main method flow for adjusting the line width in this embodiment is as follows:

[0027] Step 101: Determine the signal layer to be operated according to the obtained signal layer instruction.

[0028] Step 102: Determine, according to the obtained line width instruction, the routing that needs to be adjusted in line width in the signal layer that needs to be operated.

[0029] Step 103: Determine the line width to which the trace needs to be ...

Abstract

The present invention discloses a method for adjusting line width, and is used for increasing the efficiency of line width adjustment and reducing the error rate. The method of the invention comprises the following steps: confirming a signal layer which requires operation according to the obtained signal layer instruction; confirming the routing of line width requiring adjustment in the signal layer which requires operation according to the obtained line width instruction; confirming the line width of routing, which requires adjustment, according to the characteristic impedance included in the obtained characteristic impedance instruction; obtaining the end coordinate of routing requiring line width adjustment from a plate manufacturing file; and redrawing the routing according to the obtained end coordinate and the line width requiring adjustment. The invention also discloses a device used for realizing the method.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for adjusting line width. Background technique [0002] With the development of science and technology, especially the development of integrated circuits, the volume of products is getting smaller and smaller, with more and more functions, and the required integration is higher. The density and number of traces on a printed circuit board (Printed Circuit Board, PCB) are also continuously increasing. [0003] see Figure 1A As shown, a PCB is generally composed of a surface signal layer (top signal layer and bottom signal layer), an inner signal layer, a reference layer, and a dielectric layer (composed of insulating materials). The connection lines between components on the signal layer in the PCB are usually called traces. The signal layer and the reference layer are collectively referred to as a stack, and the stack types include the signal layer and t...
