Problems solved by technology

[0004] In the current design software, only the hole spacing can be set for a single board, and the hole type cannot be highlighted. Therefore, it is necessary for the PCB layout engineer to modify the settings individually or manually search for the fan-out area of ​​the part routing one by one. The bottleneck in the board Comparing the area with the highly dense area of ​​blind and buried holes to compare all the hole spacings, the risk of omission is high and time-consuming

Abstract

The invention provides a method for checking hole spacing based on drilling classification, and the method comprises the steps: S1, setting a drilling type through employing a drilling list function physically set by a constraint manager; s2, taking the set drilling list as a benchmark, and setting the selected drilling type to be highlighted; s3, obtaining an actual constraint value list of all hole distances on the PCB; s4, taking the set drilling list as a reference, and inputting a hypothetical constraint value of the factory end; s5, setting an inspection area; s6, comparing the actual constraint value list with the assumed constraint value according to a set inspection range, and displaying the drilling types and the coordinates thereof which do not meet the spacing requirement in awindow; and S7, clicking the coordinates to check one by one. By means of the method, hole spacing checking operation of different types of drilled holes can be achieved in batches, the working efficiency and accuracy are greatly improved, and the design quality can be improved. Meanwhile, the invention also provides a device for realizing the method.

Description

technical field [0001] The invention relates to the field of PCB design, in particular to a method and device for checking hole spacing based on drill hole classification. Background technique [0002] In the PCB design process, Cadence is the most widely used software in the industry, not only because it has powerful functions and a variety of related software as support, but also because it provides an open secondary development interface and a relatively complete development language library. Users can develop according to their own needs. [0003] In the fan-out area of ​​component routing, the bottleneck area of ​​the board or the highly dense area of ​​blind holes and buried holes, usually there will be relatively small hole spacing. Whenever the circuit board completes the routing stage, the PCB Layout engineer is ready to provide relevant files. When the data is submitted to the wiring review (DFM review), how to quickly highlight between different types of drilling...
