The embodiment of the present application discloses a line inspection method and an inspection device, which are used to inspect dogbone lines. The inspection method and the inspection device can reduce a lot of man-hours, shorten the development cycle, and avoid missed inspections. It improves the stability and reliability of the calculation process. The method according to the embodiment of the present application includes: acquiring the first and last coordinates of the signal line; acquiring the coordinates of the processor, where the processor is located in the line where the signal line is located; acquiring the coordinates of the via hole, where the via hole is located where the signal line is located ; if the first coordinate is the same as the processor's coordinate and the tail coordinate is the same as the via's coordinate, or, if the tail coordinate is the same as the processor's coordinate and the first coordinate is the same as the via's coordinate If they are the same, the length and width of the signal line are determined; if the length is not within the first preset range and the width is not within the second preset range, it is determined that the signal line is faulty.
Description
technical field [0001] The present application relates to the field of system design, and in particular to a method and an inspection device for circuit inspection. Background technique [0002] In the field of printed circuit board (printed circuit board, PCB) design of cloud computing products (servers, storage, etc.) of Intel Purley and next-generation Whitley platform central processing unit (central processing unit, CPU), it is necessary to design DDR4 dog bones (Dogbone ) traces for inspection. [0003] Since Intel has strict wiring requirements for this part of the wiring, manual inspection is generally used to check the line width and line length of the DDR4Dogbone wiring. [0004] Due to the large number of DDR4 traces, manual inspection is too cumbersome and uncertain, which affects the reliability and stability of the inspection. Contents of the invention [0005] The embodiment of the present application provides a method for circuit inspection. The inspectio...
