s35: performing the step S31 again and the step S33, the number of vertical direction vias is decreased by 1;
s36: the step S35 is repeatedly executed until n is 0, and then the vertical-direction via number is reduced to m.
6. A through-hole generation system, characterized in that the through-hole generation system is used for realizing the through-hole generation method according to any one of claims 1 to 5, and comprises an input module, a judgment module, an assignment module, a processing module, a calculation module and a list processing module, wherein the input module is used for inputting the custom parameters, the custom parameters comprise the number of through holes in the horizontal direction, the number of through holes in the vertical direction, the distance between two adjacent through holes in the horizontal direction, the distance between two adjacent through holes in the vertical direction, a metal-wrapped through-hole type parameter, a through-hole shape parameter, a defined through-hole readable value and a wrapped through-hole metal layer number, the judgment module is used for judging the size of the custom parameters to generate a judgment result, and controlling the assignment module and the processing module according to the judgment result and the calculation result, the processing module is used for realizing the circular processing to generate a list for the system parameters after assignment, the system parameters comprise the vertical direction size of a metal wrapping through hole, the horizontal direction size of the through hole, the vertical direction size of the through hole, the bottom layer metal readable value of the wrapping through hole and the high layer metal readable value of the wrapping through hole, the processing module is used for realizing the circular processing according to the judgment result, the number of the metal layers of the wrapping through hole is judged to be more than 1, the circular processing is executed, the circular processing comprises the first small circular processing and the second small circular processing after the number of the through holes in the horizontal direction and the number of the through holes in the vertical direction are judged, so that the user-defined parameters and the system parameters are substituted into the through hole number list generating formula to generate a through hole horizontal direction number list and a through hole vertical direction, substituting the user-defined parameters and the system parameters into the metal list generation formula to generate a bottom metal list and a high metal list, then subtracting 1 from the number of the wrapped through hole metal layers, wherein the calculation module is used for calculating the user-defined parameters, and the list processing module is used for loading a through hole horizontal direction quantity list, a through hole vertical direction quantity list, the bottom metal list and the high metal list to generate a layout.
