[0043] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] To clearly display trace layouts on 2D drawings, surface traces in DXF files are often rendered as thin lines. However, when such DXF files are imported into 3D software for further design analysis or simulation, surface traces often become zero-width thin lines after export, as 3D software handles line width differently from 2D design software. This results in the loss of some surface traces and compromises the integrity of the PCB design.

[0045] Based on this, this application proposes the following technical solutions, please refer to the following for details:

[0046] In one embodiment, Figure 1 As shown, Figure 1 A schematic diagram of a process flow of a surface routing export method provided in an embodiment of the present application; the present application provides a surface routing export method, which specifically includes the following:

[0047] S110: unlocking the locked elements in the target file, clearing the element selection set corresponding to the target file, extracting the element ID of each routing element in the target file, and adding the ID to the element selection set.

[0048] In this embodiment, when exporting surface routing, the computer device can first unlock the locked elements in the target file to ensure that all routing elements are in an operable state, and at the same time clear the element selection set corresponding to the target file to extract the element ID of each routing element in the target file and add it to the cleared element selection set, thereby ensuring that the selection set only contains valid routing elements to avoid irrelevant elements interfering with subsequent operations.

[0049] It's understood that the target file refers to the PCB design file currently being processed by the computer—the engineering file containing circuit layout and routing information. The element ID, on the other hand, is the unique identifier for each PCB element in the target file, used to index the corresponding element. The element selection set refers to the set of selected element IDs in the target file, allowing the computer to batch process objects using that element selection set.

[0050] Specifically, the computer device can use the axlUnfixAll function to perform an unlocking operation on all elements in the target file to ensure that those routing elements that may be in a locked state and originally could not be edited or extracted are restored to an operable state to avoid missing data due to locking restrictions. At the same time, the computer device can also use the axlClearSelSet function to clear the original element selection set in the target file to clear the irrelevant selected functions that remained in the target file before, preventing old data from interfering with subsequent processing procedures. Based on this, the computer device can reselect each routing element in the target file and add its element ID to the cleared element selection set, so that the element selection set only contains all valid routing elements in the current file, thereby providing an accurate and clean data foundation for the subsequent surface routing export process.

[0051] S120: Generate a polygon list corresponding to each element ID in the element selection set in sequence, where the polygon list contains at least one point set.

[0052] In this step, after determining the element selection set of the target file through step S110, the computer device can sequentially generate a polygon list corresponding to each element ID in the element selection set. The polygon list contains at least one point set, so that the boundary information of the routing element can be more accurately described, so that the shape and position of the routing can be more accurately represented.

[0053] Specifically, when exporting surface traces, the computer device can sequentially traverse each element ID included in the element selection set and, based on the trace element corresponding to each element ID, call a specific processing function to generate a corresponding polygon list. This polygon list consists of one or more point sets, each of which represents the specific coordinate points that constitute the trace boundary, accurately converting the actual trace outline into a closed area.

[0054] It's understandable that using polygon lists allows computers to more accurately capture the boundary shapes of routing elements, thereby accurately reflecting their spatial position and dimensional characteristics on the design layer. Compared to the traditional method of representing routing using only centerlines, this polygonal representation method avoids routing identification errors caused by ignoring width information, ensuring that routing maintains its true physical size and direction when exported to subsequent 3D software or structural analysis tools.

[0055] S130: For each polygon list, perform closed filling on each point set in the polygon list to obtain a polygonal area of ​​the routing element corresponding to the polygon list.

[0056] In this embodiment, after generating the polygon list corresponding to each routing element through step S120, for each polygon list, the computer device can close and fill each point set in the polygon list to obtain the polygon area of ​​the routing element corresponding to the polygon list, so as to clarify the actual width range of the routing and avoid the loss of the routing due to missing width.

[0057] Specifically, by closing and filling each point set in the polygon list, the computer device can convert the open contour line composed of multiple boundary points into a completely closed polygonal area, so that a two-dimensional area model corresponding to the actual physical width of the route can be constructed at the geometric level, thereby more accurately expressing the true shape and spatial coverage of the route.

[0058] It's understandable that by closing each point set into a closed area and then filling it, we can ensure that the routing element, when subsequently exported as a DXF file or imported into 3D software, no longer exists as an abstract path without width, but is transformed into a structural unit with complete geometric properties. In other words, closed filling gives the routing element a clear outer contour, giving it complete width information and visible boundaries, avoiding the risk of information loss caused by using only centerlines or line segments.

[0059] S140: Exporting each routing element in the target file as a surface routing based on each polygonal area to obtain a routing file.

[0060] In this step, after generating the polygonal area corresponding to each routing element through step S130, the computer device can export each routing element in the target file as a surface routing based on each polygonal area to obtain a routing file, i.e., a DXF file, to ensure that the exported surface routing information is accurate and complete.

[0061] Specifically, based on polygonal areas with clear boundaries and width information, the computer device can process and convert each routing element in the target file one by one, export it as surface routing data, and generate a DXF file that conforms to the standard format. During the export process, the computer device can accurately map the coordinate point information and layer properties of each polygonal area to the corresponding layer and geometric structure in the DXF drawing, so that each routing is presented as a closed graphic with physical width, thereby achieving a true reproduction of the routing in the CAD drawing and avoiding the risk of interference and short circuit between the surface routing and structural parts due to partial loss of the surface routing.

[0062] Schematically, as Figure 2 As shown, Figure 2 A comparative schematic diagram of the surface routing export results provided in an embodiment of the present application; Figure 2 In the present invention, the existing technology and the method of the present application are respectively used to Figure 2 The PCB design file shown in the figure on the left is exported for surface traces. The export results of the existing technology are as follows Figure 2 As shown in the middle figure, the export results of this application are as follows Figure 2 As shown in the figure on the right, by comparing the two, the actual physical width and direction position of the surface trace derived by this application are clearer and more complete.

[0063] Furthermore, the computer device can also package the exported routing files into a compressed file for archiving, so that they can be directly transmitted and uploaded when needed later, thereby improving efficiency.

[0064] In the above embodiment, when exporting surface routing, the locked elements in the target file can be unlocked first to ensure that all routing elements are in an operable state. At the same time, the element selection set corresponding to the target file is cleared to extract the element ID of each routing element in the target file and add it to the element selection set, thereby ensuring that the selection set contains only valid routing elements and avoiding irrelevant elements from interfering with subsequent operations. Then, a polygon list corresponding to each element ID in the element selection set can be generated in sequence. The polygon list contains multiple point sets, which can more accurately describe the boundary information of the routing element, so that the shape and position of the routing can be more accurately represented. For each polygon list, each point set in the polygon list can be closed and filled to obtain the polygon area of ​​the routing element corresponding to the polygon list, so as to clarify the actual width range of the routing and avoid the loss of the routing due to missing width. Finally, based on each polygon area, each routing element in the target file can be exported as a surface routing to obtain a routing file, ensuring that the exported surface routing information is accurate and complete.

[0065] In one embodiment, the process of extracting the element ID of each routing element in the target file and adding it to the element selection set in step S110 may include:

[0066] S111: Setting a search filter, and using the search filter to search for routing elements in the target file to obtain a search result.

[0067] S112: All routing elements are selected in the target file according to the search result, and the element ID of each routing element is added to the element selection set.

[0068] In this embodiment, after clearing the original element selection set, the computer device can set a search filter and use the search filter to search for the routing elements in the target file to obtain the search results, and then select all routing elements in the target file based on the search results, and add the element ID of each routing element to the element selection set to batch process each routing element through the element selection set.

[0069] Specifically, the computer device can set a search filter through the axlSetFindFilter function, specifying that the search condition of the search filter is a routing type element, thereby limiting subsequent operations to only the routing elements in the circuit board design; after the search filter is set, the computer device can use the search filter to perform precise search operations in the target file, and automatically traverse all elements of the target file according to the set conditions, filtering out routing elements that meet the conditions as search results. Subsequently, the computer device can automatically select routing elements in the target file based on the search results, and use the axlAddSelectAll function to obtain the element ID of each routing element, so as to add them one by one to the element selection set. Here, through the centralized management of the element selection set, the efficiency and consistency of batch processing of routing elements can be improved, thereby reducing the selection omissions or data deviation problems caused by human operations.

[0070] In one embodiment, the process of sequentially generating a polygon list corresponding to each element ID in the element selection set in step S120 may include:

[0071] S121: For each element ID in the element selection set, determine the layer where the element ID is located.

[0072] S122: extracting the routing outline of the corresponding routing element from the design database based on the element ID and the layer where it is located, and generating a polygon list according to the routing outline.

[0073] In this embodiment, for each element ID in the element selection set, the computer device can determine the layer where the element ID is located, and then extract the routing outline of the corresponding routing element from the design database based on the element ID and the layer where it is located, and generate a polygon list based on the routing outline to clarify the actual width range of the routing and avoid routing loss due to missing width.

[0074] Among them, the design database refers to the internal data system used by PCB design software to store and manage various design element information of the circuit board during the design process. It can contain data such as the element type, element ID, geometric information, layer information, etc. of each element in the target file.

[0075] Specifically, the computer device can first determine the layer in the target file where the routing element corresponding to the element ID is located, that is, determine whether it belongs to the top layer, bottom layer or other signal layer, to ensure that the subsequent contour extraction process can be carried out in the correct layer context. After obtaining the layer, the computer device can further retrieve the geometric information related to the routing element from the design database based on the element ID and its layer, and accurately parse the geometric information of the routing element by calling the axlPolyFromDB function to extract the routing contour that describes its boundary shape. The routing contour can be composed of multiple coordinate points in sequence, representing the true geometric boundary of the routing, rather than just the center line segment; therefore, based on the routing contour, the computer device can construct a polygon list corresponding to the routing element, so as to fully reflect the actual physical width and direction position of the routing element, ensuring that it has a clear geometric meaning in the graphic expression and data export process.

[0076] In one embodiment, the process of generating a polygon list according to the routing profile in step S122 may include:

[0077] S1221: Determine a geometric structure of a routing profile; the geometric structure is composed of at least one line segment.

[0078] S1222: Describe the boundary of the geometric structure to obtain the structure outline corresponding to each line segment.

[0079] S1223: Determine the coordinates of multiple points of each structure outline, form a point set corresponding to each structure outline, and generate a polygon list based on each point set.

[0080] In this embodiment, after obtaining the routing profile of a routing element, the computer device can determine the geometric structure of the routing profile. This geometric structure is composed of at least one line segment. Therefore, the computer device delineates the boundary of the geometric structure and obtains the structural outline corresponding to each line segment. The computer device then determines the coordinates of multiple points in each structural outline to form a point set corresponding to each structural outline, and generates a polygon list based on each point set.

[0081] Specifically, the computer device can identify and analyze the geometric structure of the routing contour, which is usually composed of at least one line segment, including but not limited to straight line segments, arc segments or other continuous path units. These line segments constitute the basic contour form of the routing element in physical space. On this basis, the computer device can depict the boundary of the geometric structure, that is, outline each line segment according to its starting point and end point, thereby generating a corresponding structural outline for each line segment. The structure not only records the type, size, direction and other attributes of the line segment, but also includes the spatial position relationship of its boundary. Then, the computer device can extract the coordinates of multiple points that constitute the boundary from each structural outline. These point coordinates can accurately describe the distribution of the edge of the line segment in the plane space. The computer device organizes these coordinates in order into a point set, representing a closed or semi-closed geometric area, and summarizes each point set to obtain a list of polygons corresponding to the routing element.

[0082] In one embodiment, the process of performing closed filling on each point set in the polygon list to obtain the polygonal area of ​​the routing element corresponding to the polygon list in step S130 may include:

[0083] S131: For each point set in the polygon list, perform line segment closing and area filling according to the coordinates of each point in the point set to generate a structure.

[0084] S132: Perform region combination according to the region positions of each structure to obtain a polygonal region.

[0085] In this embodiment, for each point set in the polygon list, the computer device can close the line segments and fill the area according to the coordinates of each point in the point set to generate a structure, and then combine the areas according to the area positions of each structure to obtain a polygonal area.

[0086] Specifically, the computer device can use the axlDBCreateShape function to process the coordinates of each point in the point set, and connect these points in a certain order, perform a line segment closing operation, ensure that the coordinates of the first and last points form a closed contour, and then perform a region filling operation on the inside of the closed contour, define the spatial area surrounding the contour boundary as a valid graphic entity, and encapsulate the graphic area in the form of a structure. Each structure contains the geometric properties of the represented area, a coordinate point set, layer information, and related routing attribute labels. After the closure and filling of each point set is completed, the computer device can perform position identification and spatial association judgment on all generated structures, and perform region combination operations based on the regional coordinate position and spatial relationship of each structure, that is, merge multiple adjacent, overlapping, or nested structures into a larger continuous polygonal area, and finally generate a polygonal area that represents the actual spatial distribution of the routing.

[0087] In one embodiment, the process of exporting each routing element in the target file as a surface routing based on each polygonal area in step S140 to obtain the routing file may include:

[0088] S141: setting export parameters according to the export requirements of the target file, and adjusting and exporting parameters of each polygonal area using the export parameters to generate a surface routing corresponding to each routing element.

[0089] S142: Generate a routing file based on each surface routing.

[0090] In this embodiment, when exporting surface routing, the computer device can set export parameters according to the export requirements of the target file, and use the export parameters to adjust and export parameters of each polygonal area to generate surface routing corresponding to each routing element, and then generate routing files based on each surface routing.

[0091] Specifically, the export parameters set by the computer device include but are not limited to unit settings, routing file format version, layer mapping method, line width processing method, whether to export closed graphics, whether to retain fill information, and exported coordinate accuracy, etc., in order to ensure that the exported content meets the technical standards and format requirements of subsequent usage scenarios. Based on the export parameters, the computer device can perform parameter adaptation and format conversion on each polygonal area generated in the early stage, thereby perfectly matching the geometric structure with the export format; then, the computer device can export each adjusted polygonal area as a separate surface routing graphic, and then encapsulate it into a DXF file, thereby ensuring that the geometric form, spatial position and routing attributes of the surface routing remain consistent and identifiable in the DXF file.

[0092] For example, when the export parameters are set to "-u mm -f 14 -s -p -l -cl", the computer device will specify the dimension unit of the DXF file as millimeters through the "-u mm" parameter, ensuring that all coordinates and geometric dimensions are expressed in millimeters; the "-f 14" parameter specifies that the DXF file format is compatible with AutoCAD 2014 version, enhancing the file's versatility and readability in mainstream CAD software; the "-s" parameter specifies that the surface traces in the DXF file are filled with solid lines to retain the real physical boundaries of the traces; the "-p" parameter specifies that the pads in the DXF file are filled with solid lines, thereby improving the integrity and visualization of the graphics; the "-l" parameter specifies that images representing lines in all layers in the DXF file are created to avoid missing local traces due to missing layers; and the "-cl" parameter specifies that closed graphics in the DXF file are filled with colors, where "l" means filling by layer color, thereby enhancing the readability and recognition efficiency of the DXF file in subsequent viewing and analysis. Therefore, using this export parameter can ensure that the exported DXF file has a standardized structure, complete graphics, and rich information.

[0093] In one embodiment, the method may further include:

[0094] S150: After the polygonal area of ​​the routing element is generated, the element ID of the routing element is removed from the element selection set.

[0095] In this embodiment, after generating the polygonal area corresponding to a routing element, the computer device can remove the element ID of the routing element from the current element selection set to prevent repeated processing of the routing element. By removing the element ID, the element selection set is dynamically updated during the surface routing export process, ensuring that the element selection set only contains routing elements that have not yet completed contour extraction and graphic conversion, thereby achieving orderly control and efficient scheduling of the entire processing flow.

[0096] The surface wiring exporting device provided in an embodiment of the present application is described below. The surface wiring exporting device described below and the surface wiring exporting method described above can be referenced to each other.

[0097] In one embodiment, Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of a surface routing export device provided in an embodiment of the present application. The present application also provides a surface routing export device, including an element selection module 210, a list generation module 220, an area determination module 230, and a file export module 240, specifically including the following:

[0098] The element selection module 210 is used to unlock locked elements in the target file, clear the element selection set corresponding to the target file, and extract the element ID of each routing element in the target file and add it to the element selection set.

[0101] The file export module 240 is used to export each routing element in the target file as a surface routing based on each polygonal area to obtain a routing file.

[0102] In the above embodiment, when exporting surface routing, the locked elements in the target file can be unlocked first to ensure that all routing elements are in an operable state. At the same time, the element selection set corresponding to the target file is cleared to extract the element ID of each routing element in the target file and add it to the element selection set, thereby ensuring that the selection set only contains valid routing elements and avoiding irrelevant elements from interfering with subsequent operations. Then, a polygon list corresponding to each element ID in the element selection set can be generated in sequence. The polygon list contains at least one point set, thereby more accurately describing the boundary information of the routing element, so that the shape and position of the routing can be more accurately represented. For each polygon list, each point set in the polygon list can be closed and filled to obtain the polygon area of ​​the routing element corresponding to the polygon list, so as to clarify the actual width range of the routing and avoid the loss of the routing due to missing width. Finally, based on each polygon area, each routing element in the target file can be exported as a surface routing to obtain a routing file, ensuring that the exported surface routing information is accurate and complete.
