  • Patent number: 11604916
    Abstract: A method for detecting an open/short circuit on a PCB design layout includes: reading PCB data of a to-be-checked PCB design layout, to output an image of each PCB layer included in the PCB design layout; performing a first connectivity analysis on the image of each PCB layer to classify pad patterns connected with each other in the same layer into a corresponding child network group; performing a second connectivity analysis to classify child network groups in which pad patterns connected by the same electroplated hole, into a corresponding parent network group; reading IPC netlist data of the PCB design layout, to obtain a netlist network group in which each pad pattern is; and determining whether a netlist network relationship of the pad patterns is consistent with a network relationship obtained after the second connectivity analysis in order to determine whether there is an open/short circuit.

  • Patent number: 11330705
    Abstract: The present disclosure provides a method, system and apparatus for detecting polarity of component, and a computer-readable storage medium. The component polarity detection method includes: selecting first component symbols similar to graphs in a pre-created template library of component polarity symbols from a polar graph layer of a to-be-detected printed circuit board (PCB), and sifting out second component symbols each having polarity from the selected first component symbols; and traversing each second component symbol having polarity, to detect whether a polarity symbol that has been already stored in the template library is in the second component symbol having polarity; if yes, examining whether a polarity position of the polarity symbol in the second component symbol is correct; and if the polarity position is incorrect, outputting a report indicating that the polarity position of the polarity symbol in the second component symbol is incorrect.

  • Publication number: 20210303542
    Abstract: An EDA pad package library updating/application method and system, a medium, and a terminal. The method includes: extracting a graphic data of a pad and setting information of a component based on the pad from an EDA wiring data; querying and downloading a graphic model of the component according to attribute information of the component; forming a simulated package pad by simulating and assembling the graphical model of the component and the graphical data of the pad according to setting information of the component based on the pad; storing the simulated package pad in a model database, updating an existed EDA pad package library by associating the simulated package pad to a predetermined keyword/words in the model database. A package pad created by others can be quickly obtained without a package pad library. The best pads that have been verified can be updated continuously and quickly.
