Abstract

The invention discloses a PCB device bit number design and wrongly marked position inspection method, and belongs to the technical field of EDA. The design method includes the steps that one layer is reserved in a PCB for bit number design, wherein the layer comprises device edge shapes and device bit numbers, and the bit number positions correspond to the device shape positions in a one-to-one mode; lines with a width of 6 are used for the bit numbers, and lines with a width of 1 are used for the device shapes. Compared with the prior art, the PCB device bit number design and wrongly marked position inspection method has the advantages of being reasonable in design, convenient to operate and the like, corresponding devices can be found when inspection board cards are debugged, wrongly marking can be avoided, the situation that non-corresponding inspection is missed due to man-made reasons is avoided, PCD design efficiency is improved, the problem that the bit numbers cannot be placed due to the fact that the board cards are too dense is solved, and powerful guarantees are provided for debugging, producing and testing board cards later.

Description

In a kind of PCB, device item designs and mislabels position inspecting method

Technical field

The present invention relates to EDA technical field, specifically in a kind of PCB, device item designs and mislabels position inspecting method.

Background technology

EDA technology is exactly taking computer as instrument, designer is on eda software platform, with Hardware Description Language VHDL complete design file, then by automatically completion logic compiling of computer, abbreviation, cut apart, comprehensively, optimization, layout, wiring and emulation, until for work such as adaptation compiling, logical mappings and the program downloads of specific objective chip.The appearance of EDA technology, has greatly improved efficiency and the operability of circuit design, has alleviated designer's labour intensity.

Pcb board is printed circuit board, claim again printed circuit board (PCB), printed substrate, be called for short wiring board, the normal english abbreviation PCB(Printed circuit board that uses) or write PWB(Printed wire board), taking insulation board as base material, be cut into certain size, on it, at least has a conductive pattern, and cloth porose (as component hole, fastener hole, plated-through hole etc.), be used for replacing the chassis of in the past installing electronic devices and components, and realize interconnecting between electronic devices and components.Because this plate is to adopt electron printing to make, therefore be called as " printing " circuit board.

Along with pcb board is towards high-accuracy future development, device is more and more less, plank design is more and more less, space is more and more less, practical function is more and more, item can not be adjusted and be shown on plank, and is easy to the corresponding mistake of mark, therefore in the urgent need to improving our corresponding method for designing of platform.

Summary of the invention

Technical assignment of the present invention is to provide device item in a kind of PCB and designs and mislabel position inspecting method.

Technical assignment of the present invention is realized in the following manner, in this PCB, device item method for designing step is as follows: in PCB, reserve an aspect and design item, this layer comprises device edge shape, device item, and item position and device shape position are corresponding one by one; The line that item is 6 with width, the line that device shape is 1 with width.

Described item lines and the color of device shape lines can freely arrange.

Described item lines are different with the color of device shape lines.

In PCB, to mislabel position inspecting method step as follows for device item: when inspection when item and device shape are mated when correct without prompting, displaying symbol "×" in the middle of edge shape in the time that coupling is incorrect, corresponding output item error checking table, in the time that coupling is correct, check table prompting all coupling is correct; In the time having matching error to occur, the corresponding output of the check table item information of makeing mistakes; Then according to prompting amendment error message, after amendment, rerun device item error checking table, until all correct.

Described symbol "×" size and color can freely arrange.

Described symbol "×" size and color are different.

In a kind of PCB of the present invention, device item designs and mislabels position inspecting method compared to the prior art, there is the features such as reasonable in design, easy to operate, while utilizing the method can meet bug check board, find corresponding device, can also avoid mark to make mistakes, avoid artificial origin to miss some not correspondence provings, thereby improve PCB design efficiency, and solved due to the too close problem that cannot put item of board, for follow-up debugging, production, test board provide the barrier of trying hard to keep.

Brief description of the drawings

Accompanying drawing 1 is the schematic flow sheet that in a kind of PCB, device item designed and mislabeled position inspecting method.

Embodiment

Embodiment 1:

In PCB, reserve an aspect and design item, this layer comprises device edge shape, device item, and item position and device shape position are corresponding one by one; The line that item is 6 with width, the line that device shape is 1 with width.When inspection when item and device shape are mated when correct without prompting, displaying symbol "×" in the middle of edge shape in the time that coupling is incorrect, corresponding output item error checking table, in the time that coupling is correct, check table prompting all coupling is correct; In the time having matching error to occur, the corresponding output of the check table item information of makeing mistakes; Then according to prompting amendment error message, after amendment, rerun device item error checking table, until all correct.

Embodiment 2:

In PCB, reserve an aspect and design item, this layer comprises device edge shape, device item, and item position and device shape position are corresponding one by one; The line that item is 6 with width, the line that device shape is 1 with width, the color of item lines and device shape lines can freely arrange.When inspection when item and device shape are mated when correct without prompting, displaying symbol "×" in the middle of edge shape in the time that coupling is incorrect, symbol "×" size and color can freely arrange, corresponding output item error checking table, in the time that coupling is correct, check table prompting all coupling is correct; In the time having matching error to occur, the corresponding output of the check table item information of makeing mistakes; Then according to prompting amendment error message, after amendment, rerun device item error checking table, until all correct.

Embodiment 3:

In PCB, reserve an aspect and design item, this layer comprises device edge shape, device item, and item position and device shape position are corresponding one by one; The line that item is 6 with width, the line that device shape is 1 with width, item lines are different with the color of device shape lines.When inspection when item and device shape are mated when correct without prompting, displaying symbol "×" in the middle of edge shape in the time that coupling is incorrect, symbol "×" size and color are different, corresponding output item error checking table, in the time that coupling is correct, check table prompting all coupling is correct; In the time having matching error to occur, the corresponding output of the check table item information of makeing mistakes; Then according to prompting amendment error message, after amendment, rerun device item error checking table, until all correct.

By embodiment above, described those skilled in the art can be easy to realize the present invention.But should be appreciated that the present invention is not limited to above-mentioned several embodiments.On the basis of disclosed execution mode, described those skilled in the art can the different technical characterictic of combination in any, thereby realizes different technical schemes.
