Due to the time of the listing, the = factor is also as good as manual wiring 18868 5 1290675 has been difficult to do 'and must rely on the special # software for auxiliary design. Wiring 2 AUegrQ is a kind of auxiliary line that is widely used in the current world. AUegro provides a good and interactive working interface and powerful:: for the current high-speed, high-density, multi-layer complex circuit board A better solution 'in addition, it has a strong impact factor' setting, users only need to set the wiring rules according to the requirements, eliminate all design rule checks (DRG) errors in the wiring to meet the wiring design requirements. This saves the complexity; the manual inspection time '俾 improves the work efficiency. · Second, just like this, the current wiring software such as AUegr〇 still has many shortcomings after the completion of the design rule check. First, its Design rule check-checking All design rule check errors are displayed in the same display mode, making it difficult for engineers to distinguish the specific design rules. What type of error is checked, and it is difficult to modify the design rule check errors in different categories. The design rules of the wiring software are generally too rigid, for the part of the appeal It's not the wrong wiring, it still reports the design rules to check the wrong ones. A board often has dozens of hundreds of such errors, engineers must exclude them from the errors that really need to be processed, not only waste a lot of time, but also It may cause unnecessary trouble to the board design due to the process of the exclusion process. Therefore, 'how to provide a design error checking system and method to avoid the above-mentioned various shortcomings of the prior art is an urgent problem to be solved in the industry. SUMMARY OF THE INVENTION 6 18868 1290675 • In view of the above-mentioned problems of the prior art, the main object of the present invention is to provide an inspection system and method for designing errors, which can classify errors that are faced after different rules are set.

[Embodiment] The embodiments of the present invention are described by way of specific specific examples. Those skilled in the art can readily appreciate the advantages and advantages of the present invention as disclosed in the present disclosure. The present invention may also be practiced by other specific embodiments. Or application, the details in this manual can also be based on different opinions and should be Various modifications and changes are made in the spirit of the invention. - Referring to Figure 1, there is shown a block diagram of the design of the design error of the present invention. As shown, the design of the design of the wrong system 1 of the present invention, It is applied to the wiring system of a circuit board, so that when the circuit layer of the circuit board is subjected to the design rule check (DRC), it is determined that the error is correct. Ignoring or not <ignoring, 'to improve the efficiency of debugging. The wiring system of the circuit board described in this embodiment is, for example, A1 legro wiring software. The design of the design of the wrong system 1 includes: setting module 11, The layer selection module 12, the classification module 13, the determination module 14, and the prompt module 15 'where the system 1 includes the export module 16 and the storage module 17 ° or less, that is, the setting module 11 and the layer selection mode The group 12, the classification module 13, the determination module 14, the prompt module 15, the export module 16, and the storage module 17 are described in detail. The setting module 11 is used for the user to set the design error judgment 9 18868 1290675In the present invention, the judging rule includes at least a through-thru via spacing error determination rule and a line to line spacing error judging rule. Occurs in the power supply layer of the circuit board, which may cause errors when the through-holes are overlapped with the traces during wiring. The design rule check is performed in the circuit board wiring system to indicate that the through-hole spacing error occurs. The same as the name of the trace (net > Xia), the circuit board designed according to this will be short-circuited. Therefore, the error caused by the overlap of the through-hole and the trace can not be ignored. The name of the through-hole is different from the name of the trace. Therefore, the circuit board designed after wiring is not in a bad condition. At this time, the error is a negligible error, and the error does not need to be marked as a design rule check. The error is that the error can be eliminated. In this embodiment, the erroneous determination of the through-hole spacing set by the setting module 11 is that the through-hole spacing error is regarded as a non-negligible error when the names of the overlapping lines of the through-hole tray are the same. For errors that can be ignored. The line spacing error occurs on the top layer of the board (t〇p!machi) or the bottom layer (buU〇m layer), which is caused by the distance between two adjacent traces being less than the preset spacing of the user. Wrong, the current circuit board wiring system will prompt the error determined by the design rule check when the board trace is less than the preset distance. However, when the two traces are connected with pins and go When the line length is less than the user's default value, the error does not cause a missing board design 'so the error is considered an error that can be ignored'. It is a non-negligible error only if the above conditions are not met. 18868 1290675 and must be modified. In this embodiment, the line spacing error determination rule set by the setting module u is such that if the coordinates of the two ends of the two lines coincide with the center coordinates of the included pins, and the lengths of the two lines are less than one pre- If the value is set, the line spacing error is regarded as a non-negligible error, otherwise it is regarded as a negligible error 'where' the preset value can be preset according to the user's specific needs. The layer selection module 12 is used to select a wiring layer for design rule checking. The current circuit board is generally a structure such as a five-layer board, a seven-layer board or more layers. Select any layer or a combination of any multiple layers from multiple layers for subsequent design rule checking. The classification module and the group 13 are used to classify the wiring layers selected by the layer selection module 11, and are classified according to errors that are faced after the design rule is checked. In this embodiment, the error that the DRC will face is In a plurality of categories, for example, a through-hole spacing error and a line spacing error, etc., in the present invention, only the DRC processing for the through-hole spacing error and the line spacing error is taken as an example. It is to be noted that the present invention is not limited thereto. The determining module 14 is configured to determine, by the setting rule set by the setting module 11 and the error category of the t type, that the circuit board is wired after the design rule check: whether the determined error is a negligible error, and accordingly The judgment result 'is subsequently processed by the module 15 for the processing result. As described above, if the error faced by the DRC selected by the user belongs to the type of the through-hole 2 error, the determination module 14 determines the rule of the through-hole spacing error set according to the setting module 1丨. The name of the through hole and the trace overlapping with 18868 11 1290675 is the same. If the name is the same, the error is judged to be an unrecognizable design rule check error. If you do not know that ^ is not the same, the error is regarded as a negligible error. At the same time, it is possible to eliminate the error and eliminate the error and avoid a lot of manpower and time to modify it. The error that you will face after changing the DRC selected by the right user belongs to the category of line spacing error. The judgment module 14 compares the two traces according to the line spacing error judgment rule of the setting module 11. Whether the coordinates of the two endpoints coincide with the center of the pin + the ancient hitter τ丄 cake, if the ends of the two traces sit

In the embodiment, the prompting module 15 will not ignore the error; and the display unit can prompt the debugger to display an error in a high-brightness manner through, for example, the illumination module. In addition, the prompt module 15 can also be voice-activated. Or the text does not provide a prompt action, but these prompt methods are known, so it is no longer traced here.
