[0005] In the PCB revision design, the version of the part may be inconsistent. However, the Cadence Allegro wiring design software cannot check whether the current version of the part in the PCB is consistent with the corresponding package library version in the specified package library. If there is a current version of the part Inconsistency with the version of the package library, but not checked out, may make the PCB unable to achieve the functions required by the design

Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings.
[0024] figure 1 It is a schematic flow chart of the PCB inspection method of the present invention, as figure 1 shown, including the following steps:
[0025] Step 11, obtaining package information of all parts on the PCB, wherein the package information includes package names and current versions of the parts on the PCB.
[0026] The inspection of the PCB in the present invention can be completed by using the Cadence Allegro wiring design software and the Cadence AXLSKILL development language. Specifically, use the SKILL design program of the Cadence AXLSKILL development language, and load the SKILL design program into the Cadence Allegro wiring design software for user-defined development and use, and can write functions that realize required functions, such as in the present invention , the user can pre-set the function used to cal...

The invention provides a PCB check method and device. The method includes the steps that packaging information of all parts on a PCB is acquired, wherein the packaging information contains packaging names and current versions of the parts on the PCB; the path of an assigned packaging base of the PCB is acquired; according to the acquired packaging names of the parts, the packaging base version corresponding to each part on the PCB is searched for in the packaging base; the current version and the packaging base version of each part on the PCB are compared respectively, so that the PCB is checked. Through the PCB check method and device, the accuracy of the versions of the parts of the PCB is guaranteed, operation is easy, and less time is consumed.
Description
technical field [0001] The invention relates to the technical field of printed circuit board (PCB, Printed Circuit Board) design, in particular to a PCB inspection method and device. Background technique [0002] PCB is one of the important components of the electronics industry. Almost every kind of electronic equipment, ranging from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, for the sake of communication between them For electrical interconnection, PCBs are used. [0003] With the rapid development of science and technology, the design performance and function requirements of PCB are getting higher and higher, so it is difficult to meet the design requirements through one design. The completed PCB for the initial design needs to go through various stages of verification such as design verification, simulation verification, and test...
