  • Patent number: 7346870
    Abstract: A method for verifying trace widths of a printed circuit board (PCB) layout includes the steps of: loading a PCB layout document from a database; defining a verifying area for a PCB layout specified in the PCB layout document; receiving preset design rules; creating a data structure, and loading information on traces in the verifying area into the data structure; selecting an unverified trace from the data structure; selecting an unverified segment from the selected trace; verifying the selected segment by comparing a width of the selected segment with the rules, and determining whether the selected segment satisfies the rules according to the comparison result; and annotating design rule check (DRC) information if the segment does not satisfy the rules. Other segments of the selected trace and other traces are verified by repeating appropriate of the above-described steps. A related system for implementing the method is also disclosed.

  • Patent number: 7206711
    Abstract: A system for automatically comparing test points of a PCB includes an application server (1) and a database (6). The application server includes: a PCB file selecting module (10) for selecting a target file and a source file from the database; a test point data extracting module (12) for extracting test point data from the target file and the source file; a table generating module (14) for generating a target table according to the extracted test point data from the target file and generating a source table according to the extracted test point data from the source file; a comparing module (16) for comparing the test point data of the target table and the source table one by one and storing comparison results on those test points which have been modified; and a report generating module (18) for generating a comparison report. A related method is also disclosed.
