Embodiment 1

[0028] Refer to attached figure 1 - attached figure 2 , the cutting method of a kind of PCB layout of this embodiment, finds all passages in the area to be cut in PCB layout and divides passages into groups, divides the passages with similar distance into the same group, carries out external expansion according to the shape of the passages, external expansion Stop expansion when overlapping is required during the process, combine the overlapping channels into a group, and obtain the outer contours of all groups after expansion, and obtain the number of channels in each contour. When the number of channels is greater than 16, it needs to be cut until the cutting Cutting is stopped when the number of channels in the final outline is less than 16, and the desired model after cutting is obtained.

[0029] Preferably, it specifically includes the following steps:

[0030] S100. Obtain the area to be cut, find the vias of all channels in the area to be cut according to the given ...

Abstract

The present invention provides a cutting method of a PCB layout. The method comprises the steps of: finding and grouping all channels in a to-be-cut area in the PCB layout, dividing the channels withthe close distances into the same group, performing outward expansion according to the shapes of the channels, stopping outward expansion when overlapping is needed in the outward expansion process, combining the overlapped channels into one group, and obtaining the outer contours of all the groups after outward expansion; and obtaining the number of channels in each contour, cutting when the number of the channels is greater than 16, and stopping cutting until the number of the channels in the cut contour is less than 16 to obtain a required cut model. A large layout is effectively cut into models with corresponding sizes according to user requirements, through hole channels with close distances are cut into the same model, crosstalk analysis on signals in the models is facilitated, and real and effective crosstalk data is provided for users.

Description

technical field [0001] The invention belongs to the technical field of electronic design simulation, and specifically relates to a method for cutting a PCB layout. Background technique [0002] PCB designers use this software to design layouts. During the design process, they need to simulate and check the crosstalk in the layout to find out the modules with excessive crosstalk. However, since there is almost no excellent crosstalk analysis and simulation software on the market today, designers need to obtain crosstalk information through cumbersome calculations. [0003] Aiming at this problem, the present invention proposes a method of cutting the layout and performing simulation calculation. According to the user's setting parameters, the layout is cut according to certain cutting rules, and the signals within a certain distance range are cut into a model, and The model information is transmitted to the simulation solver, the crosstalk is calculated through simulation, a...
