The embodiment of the invention discloses a line inspection method and an inspection device, which are used for inspecting a Dogbone line of a dog bone, and through the inspection method and the inspection device, a large amount of working hours can be reduced, the development period can be shortened, the condition of missing inspection can be avoided, and the stability and reliability of the calculation process can be improved. The method disclosed by the embodiment of the invention comprises the following steps: acquiring the head coordinate and the tail coordinate of the signal line; obtaining coordinates of a processor, wherein the processor is located in a line where the signal line is located; obtaining coordinates of a via hole, wherein the via hole is located in a line where the signal line is located; if the head coordinate is the same as the coordinate of the processor and the tail coordinate is the same as the coordinate of the via hole, or if the tail coordinate is the sameas the coordinate of the processor and the head coordinate is the same as the coordinate of the via hole, determining the length and width of the signal line; and if the length is not in the first preset range and the width is not in the second preset range, determining that the signal line has a fault.
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...
