The detailed features and advantages of the present invention are described in detail below in the implementation mode, and its content is enough to make any person familiar with the related art understand the technical content of the present invention and implement it accordingly, and according to the content disclosed in this specification, the scope of the patent application and the drawings , anyone skilled in the art can easily understand the purpose and advantages of the present invention. The following examples are to further describe the concept of the present invention in detail, but not to limit the scope of the present invention in any way.

The method for comparing electronic circuit diagrams provided in various embodiments of the present application can be executed by a processor, such as a central processing unit, a programmable logic controller, a microcontroller, or other electronic devices with data processing functions. The processor can receive two different versions of electronic circuit diagram files (such as the previous version of the electronic circuit diagram file and the later version of the electronic circuit diagram file), and in this paper, the two electronic circuit diagram files are respectively defined as the first electronic circuit diagram file and the second electronic circuit diagram file. 2. Electronic circuit diagram files. It is worth noting that the above-mentioned first and second electronic circuit diagram files do not allude to the version of the electronic circuit diagram file sequence, and the first and second electronic circuit diagram files can also be two versions of a parent electronic circuit diagram file, or electronic circuit diagram files separated by several generations of version differences, in short, as long as the two can produce corresponding comparison All of the electronic circuit diagram files can become the first and second electronic circuit diagram files mentioned in this case, and this part should not be a limitation of this case. In addition, as for the method of comparing more than three electronic circuit diagram files at the same time, if the process is based on pairwise comparison, it can be based on the claims of this case and thus fall within the scope of protection of this case.

Please refer to FIG. 1 . FIG. 1 is a flowchart of a method for comparing electronic circuit diagrams according to an embodiment of the present invention. As shown in Figure 1, the electronic circuit diagram comparison method includes step S1: converting the first electronic circuit diagram file into a first text file; step S3: converting the second electronic circuit diagram file into a second text file; step S5: converting The first text file is compared with the second text file to obtain a difference text file including at least one text difference between the first text file and the second text file; and step S7: generating a difference image file according to the difference text file, wherein the difference image file At least one difference point on is marked corresponding to the at least one text difference.

Before step S1 and step S3, after receiving the first and second electronic circuit diagram files, the processor may convert the first electronic circuit diagram file into a first text file (step S1) and convert the second electronic circuit diagram file It is the second text file (step S3). The processor may also perform step S1 upon receiving the first electronic circuit diagram file in advance, and then perform step S3 upon receiving the second electronic circuit diagram file. As mentioned above, there is no difference in order between the first electronic circuit diagram file and the second electronic circuit diagram file, so the order of step S1 and step S3 can be exchanged or processed in parallel.

In step S5, the processor compares the first text file with the second text file to obtain a difference text file including at least one text difference. Specifically, the comparison referred to in this case can be used to judge whether two text files are equal, that is, whether or not in the program operation is equal, which can generate Such as the result of Boolean value (Boolean); however, for other types of comparison, such as subtracting two data to obtain a zero value (indicating the same) or a non-zero value (indicating the difference), or other types can produce similar The calculation method of efficacy should also fall within the protection scope of this case because it also has comparative effects. On the other hand, the main difference between the text file and the image file referred to in this case lies in the different presentation methods, so the text file can contain text, numbers, indicators (pointer) or other above-mentioned text, numbers and indicators (pointer) with attributes ) data structures or types such as tree (tree), linked list (linked list), stack (stack) and array (array), etc., rather than data types containing only simple text, so this part should not be included in this case limitation factor.

In step S5, the text differences can represent similar difference information in other electronic circuits such as circuit differences or component differences; on the other hand, if there is no difference between the two text files, a difference text file that does not include the text differences can be obtained , so that relevant personnel can confirm whether parts of the electronic circuit diagram files of the two versions have been changed; of course, under normal circumstances, the above-mentioned text difference files may contain at least one text difference. By converting the two electronic circuit diagram files into two text files, the comparison of the two text files is more meaningful to the difference between the two electronic circuit diagram files, because simply comparing the diagram files may contain more meaningless information, Such as graphics differences caused by typesetting and pagination, etc. This problem is more likely to occur especially in the case of a large number of graphics files or a large number of pages.

After the difference text file is obtained, as in step S7, a difference graphic file can be generated according to the difference text file, wherein text differences will be correspondingly marked with difference points on the difference graphic file. That is to say, relevant personnel can clearly and visually identify the difference between the first electronic circuit drawing file and the second electronic circuit drawing file through the difference drawing file generated in this step, whether it is marked by color or other patterns The differences between the two electronic circuit diagrams make the comparison of multi-page electronic circuit diagrams easier and more efficient.

Furthermore, the first text file may include the first circuit data and the first component data, and the second text file may include the second circuit data and the second component data. Please refer to FIG. 2 . FIG. 2 is a flow chart showing the comparison steps of the method for comparing electronic circuit diagrams according to an embodiment of the present invention. As shown in Figure 2, the comparison step S5 of Figure 1 may include the following steps: Step S51: compare the first circuit data with the second circuit data to obtain the circuit comparison result; step S53: compare the first component data with the second Comparing the component data to obtain a component comparison result; and step S55 : generating a difference text file according to at least one text difference associated with the circuit comparison result and the component comparison result.

Specifically, the line data can be the connection relationship between each node (node) and other nodes in the circuit diagram, and the implementation methods belong to the prior art and will not be described here. Through step S51, it can be known whether the topological structures of the two electronic circuit diagrams are equal, and the differences are obtained and recorded. Step S53 is to compare the components on each node. By comparing the components, different types of component changes can be screened out, such as resistors being replaced with capacitors, or components of the same type but with different impedance values can be screened out. It should be noted that all components must be located on the nodes, but the nodes do not necessarily have components (such as grounding points, equipotential points or endpoints, etc.). Taking step S55 as an example, no matter whether only the circuit comparison result has a difference or only the component comparison result has a difference, or both the circuit comparison result and the component comparison result have differences, a difference text file containing the difference can be generated for future use of the method in this case. steps to use.

Furthermore, the first route data may include a plurality of first route files, and the second route data may include a plurality of second route files. For lines containing multiple line files Please refer to FIG. 3 for a detailed implementation of the comparison of circuit data. FIG. 3 is a flow chart of the comparison sub-steps of the method for comparing electronic circuit diagrams according to an embodiment of the present invention. As shown in Figure 3, step S51 of Figure 2 may include: Step S511: According to the multiple file names of the first line file, obtain a plurality of corresponding target line files in the second line file; Each one is compared with each corresponding one in the first line file; Step S515: Record the difference between the target line file and the corresponding first line file as the text difference to the line difference Result; and step S517 : when the first line file and the second line file include the remaining line files that are not corresponding, record the remaining line files as the text difference to the line comparison result.

In this example, the multiple first circuit files of the first circuit data have multiple file names, wherein each file name may correspond to a circuit on the circuit board. Specifically, taking Allegro, a commonly used electronic circuit design software in the market, as an example, the circuit file can be a Nets file, and the circuit file has multiple file names corresponding to each circuit. In step S511, a plurality of file names of the plurality of first route files can be correspondingly obtained to a target route file in the plurality of second route files. In step S513, each of the target circuit files is compared with the corresponding circuit file in the first circuit file, that is, two different versions of electronic circuit files can be compared based on the same circuit. In step S515, those with differences in the circuit comparison can be recorded as the above-mentioned text differences and stored in the above-mentioned circuit comparison results. So far, the differences of the corresponding circuits in the two versions of the electronic circuit diagram files have been recorded. In step S517, for the remaining line files that are not corresponding in the first line file and the second line file, it can also be recorded as the text difference in the line comparison result, that is, for the two line files, did not do If some lines are added or deleted in the later version, the corresponding line data that cannot be generated will be recorded as text differences.

So far, the line comparison results in the difference text file in this example have covered all the line differences in the two versions of the electronic circuit diagram, including the inability to generate corresponding lines, and changes in the number and position of nodes that may be included in the corresponding lines. Regarding the comparison of component data in step S53 of this example, please refer to Figure 4 for detailed implementation. S531: Obtain multiple target component files corresponding to the second component file according to multiple file names of the first component file; Step S533: Match each of the target component files with each corresponding target component file or compare them; step S535: record the difference between the target component file and the corresponding first component file as the text difference to the component comparison result; step S537: when the first circuit file and the second circuit file When the remaining circuit files are included, the remaining component files corresponding to the remaining circuit files in the first component file and the second component file are recorded as the character difference to the component comparison result.

In this example, the first component data includes a plurality of first component files, and the second circuit data includes a plurality of second component files, and the first component file has a plurality of file names similar to the first circuit file, wherein each Each file name can correspond to a circuit on the circuit board. Specifically, taking the common electronic circuit design software Allegro in the market as an example, the component file can be Components file, and the component file has multiple file names corresponding to each circuit. Specifically, steps S531 to S535 are similar to the above steps S511 to S515, so details are not repeated here. However, it should be noted that although step S531 is to obtain the target component file in the second component file according to the multiple file names of the first component file, if you are familiar with this It can be understood by those skilled in the art that the file name in the first component file and the file name in the first circuit file belong to the first text file converted from the first electronic circuit diagram file, so they naturally have part of the same file name, or are file names that have a one-to-one relationship, i.e., have the same line. Therefore, step S531 can also obtain multiple target component files corresponding to the second component file according to multiple file names of the first circuit file. This part is a simple change and should not be a limiting condition of this case.

In step S537, in combination with the above paragraph, the remaining component files in the first circuit file and the second component file corresponding to the remaining circuit files are equal to those not corresponding to the step S531 in the first circuit file and the second component file The rest of the component files. So far, the processor in this example has obtained the text differences containing the circuit comparison results and component comparison results. In addition, it should be noted that in this example, the comparison of circuit data takes precedence over the comparison of component data, but this does not mean that comparing component data first or comparing component and circuit data at the same time is not within the scope of this case. This is just an example. illustrate.

A detailed implementation of the step of generating a difference image file with marked difference points is further described. Please refer to FIG. 5 . FIG. 5 is a flow chart of marking steps of a method for comparing electronic circuit diagrams according to an embodiment of the present invention. As shown in FIG. 5, step S7 of FIG. 1 may include step S71: mark at least one difference point with a first color on the original image file according to the first color attribute to generate a difference image file, wherein the original image file is associated with the first electronic Circuit diagram file or second electronic circuit diagram file; step S73: mark at least one non-difference point other than the difference point on the original diagram file with a second color according to the second color attribute to generate a difference diagram file. Specifically, the processor can convert the difference text file back to an electronic circuit diagram file or directly use the first electronic circuit diagram file or the second electronic circuit diagram file as the original image file, and use the first color attributes such as the red attribute The text difference of the mark produces the difference point with red mark on the original image file; Compared with the difference point, in the program, step S73 can generate a second color such as black on the original image file for the non-text difference In this way, the overall difference image file has only two distinct color contrasts, so that relevant personnel can see at a glance when looking for differences. The above-mentioned color attribute is one of the materials covered by the definition of the text file, so that when the text file is converted into a graphic file, the color attribute can be used to define the ratio of the three primary colors (RGB) displayed on the graphic file to present the desired performance color. Of course, the use of color markings is only an option for easy implementation. In other embodiments, alternative schemes that can be associated with the present invention can also be considered through pattern markings or font changes, so this part should not be a limiting condition of this case.

Among them, it can be seen that there are densely divided circuit connections and various components in Figure 6 and Figure 7, making it time-consuming and laborious for relevant personnel to confirm the differences and changes between the two versions. However, through the conversion of the electronic circuit diagram comparison method in this case After the text files are compared, marked and converted into difference image files, as shown in Figure 8, the difference 2 between the two image files can be clearly identified. In addition, it should be noted that a circuit diagram often has dozens of pages of diagram files, so the method of this case can also help filter circuit diagrams that have no changed circuits or components, so that cross-page search and cross-comparison can be realized. more convenient.

Through the present invention, the software compares the circuit diagrams of the front and back versions, and displays the modified parts in different colors. The inspection and development personnel can compare and search for cross-page comparisons in the files, and directly display the differences between the front and back versions of the files in different colors, which is convenient The R&D personnel check whether the modification is correct and in place.
