[0002] After the PCB (Printed Circuit Board) layout design is completed, layout personnel need to check the component placement to confirm its rationality. Currently, this check process mainly relies on manual work by layout personnel. The inspection effectiveness is affected by the subjective factors of the personnel performing the work; different personnel may have different results for the same layout, making it difficult to guarantee consistent inspection quality. Furthermore, with the increasing complexity of PCBA (Printed Circuit Board Assembly) design, the number of components on a PCB can reach tens of thousands. Manual inspection is labor-intensive and time-consuming, making it difficult to meet the demands for efficient and accurate layout inspection.

[0003] Therefore, how to reduce the subjective influence of manual inspection and improve the accuracy and efficiency of component spacing inspection is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a spacing inspection method, device, medium and procedure product to reduce the subjective influence of manual inspection and improve the accuracy and efficiency of device spacing inspection.

In the preset two-dimensional information structure, the target row index item corresponding to the device type of the target device and the target column index item corresponding to the device type of adjacent devices in the same layer are determined; wherein, the row direction and column direction of the two-dimensional information structure correspond to the recording of the device type set; the intersection position of any row index item and any column index item records the spacing reference parameters corresponding to the two device types in multiple relative directions respectively; Read the target spacing reference parameter corresponding to the target relative direction from the intersection of the target row index and the target column index; the target relative direction is: the direction of adjacent devices in the same layer relative to the target device; The actual distance is compared with the target distance benchmark parameter, and corresponding risk warning information is generated based on the comparison results.

[0006] Secondly, this application provides a spacing inspection device, comprising: The acquisition module is used to acquire the design file and extract the device information of each component from the design file; the device information includes the component type and the component location. The measurement module is used to determine the adjacent devices in the same layer of the target device based on the device position of the target device and the stacking structure in the design file, and to measure the actual distance between the target device and the adjacent devices in the same layer. The determination module is used to determine the target row index item corresponding to the device type of the target device and the target column index item corresponding to the device type of adjacent devices in the same layer in a preset two-dimensional information structure; wherein, the row direction and column direction of the two-dimensional information structure correspond to the recording of the device type set; the intersection position of any row index item and any column index item records the spacing reference parameters corresponding to the two device types in multiple relative directions respectively; The reading module is used to read the target spacing reference parameter corresponding to the target relative direction from the intersection of the target row index item and the target column index item; the target relative direction is: the direction of adjacent devices in the same layer relative to the target device; The comparison module is used to compare the actual distance with the target distance benchmark parameters and generate corresponding risk warning information based on the comparison results.

[0010] As can be seen, the technical effects of this application include: automatically extracting the device type and location of each component from the design file, reducing the workload of manually verifying device information one by one. By identifying adjacent components on the same layer and measuring the actual spacing, it avoids discrepancies in inspection results caused by the subjectivity of manual inspection, ensuring consistency in inspection results for the same layout by different personnel. By finding the spacing reference parameters corresponding to the device type and relative direction in a preset two-dimensional information structure, and comparing the actual spacing with the spacing reference parameters to generate risk warning information, it standardizes the spacing judgment criteria, reducing judgment deviations caused by differences in personnel experience. Simultaneously, this solution can automatically complete the measurement and comparison of device spacing, shortening the inspection cycle and improving inspection efficiency for PCB design files with a large number of components. Furthermore, by distinguishing relative directions and reading the corresponding spacing reference parameters separately, it can adapt to differentiated spacing requirements in different directions, making the inspection results more consistent with actual design needs, reducing the subjective influence of manual inspection, and improving the accuracy and efficiency of device spacing inspection.

[0011] Correspondingly, the spacing inspection device, equipment, medium, and program product provided in this application also have the above-mentioned technical effects. Attached Figure Description

[0016] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Currently, layout inspection primarily relies on manual work by layout personnel. The inspection effectiveness is influenced by the subjective factors of the personnel performing the work, and different personnel may yield different results for the same layout, making it difficult to guarantee consistent inspection quality. Furthermore, with the increasing complexity of PCBA (Printed Circuit Board Assembly) designs, the number of components on a PCB can reach tens of thousands, resulting in a large workload and long inspection cycle for manual inspection, which is insufficient to meet the demands for high-efficiency and high-accuracy layout inspection. Therefore, this application provides a spacing inspection scheme that can automatically measure and compare component spacing. For PCB design files with a large number of components, this can shorten the inspection cycle and improve inspection efficiency. In addition, by distinguishing relative directions and reading the corresponding spacing reference parameters, it can adapt to differentiated spacing requirements in different directions, making the inspection results more consistent with actual design needs. This reduces the subjective influence of manual inspection and improves the accuracy and efficiency of component spacing inspection.

[0018] See Figure 1 As shown in the figure, this application discloses a spacing checking method, including: S101. Obtain the design file and extract the device information of each device from the design file; the device information includes device type and device location.

[0019] In this embodiment, the design file is a PCB (Printed Circuit Board) design file, such as a .brd format file exported after the design is completed. The component type is used to characterize the material type of the component, such as resistors, capacitors, connectors, chips, etc. Different component types correspond to different spacing requirements. The component location is used to characterize the physical coordinates of the component on the PCB and its layer information, such as the center coordinates of the component and whether the component is located on the top or bottom layer. By extracting the component type and component location, a data foundation can be provided for subsequently determining adjacent components on the same layer, measuring the actual spacing, and querying the two-dimensional information structure, thereby avoiding manual verification of component information one by one and reducing manual workload.

[0020] S102. For the target device in each device, determine the adjacent devices in the same layer of the target device according to the device position of the target device and the stacking structure in the design document, and measure the actual distance between the target device and the adjacent devices in the same layer.

[0021] Among them, the stacked structure is the structural information defined in the design file to distinguish between the top and bottom layers.

[0022] In one implementation, the design file contains multiple devices, each of which can be sequentially used as a target device for spacing checks. Distinguishing between top-level and bottom-level devices through a layered structure ensures that spacing comparisons are performed only within the same physical layer, avoiding confusion in coordinate calculations between top-level and bottom-level devices. Adjacent devices on the same layer refer to devices located on the same layer as the target device and surrounding it, such as devices whose distance from the target device is less than a preset threshold. Measuring the actual spacing between the target device and its adjacent devices on the same layer provides numerical data for subsequent comparison with spacing benchmark parameters.

[0023] In one embodiment, measuring the actual spacing between a target device and adjacent devices on the same layer includes: using the maximum range of the stencil layer outline and the silkscreen layer outline of the target device as the measurement layer for the target device; using the maximum range of the stencil layer outline and the silkscreen layer outline of adjacent devices on the same layer as the measurement layer for those adjacent devices; and measuring the distance between the edge of the target device and the edge of the adjacent devices on the same layer based on the measurement layers of the target device and the adjacent devices to obtain the actual spacing. Here, the stencil layer is a layer used for solder paste printing, and its range corresponds to the actual mounting area of ​​the device; the silkscreen layer is a layer used to represent the outline of the device, and its range corresponds to the silkscreen outline of the device. For some devices, due to their special body shape, the silkscreen outline may be larger than the body pads, meaning the silkscreen layer range is larger than the stencil layer range. By selecting the larger of the two ranges as the measurement layer, the actual physical space occupied by the device can be accurately reflected, avoiding overly lenient spacing determination due to measuring only the pads or overly strict spacing determination due to measuring only the silkscreen. If the outline of the stencil layer and the outline of the silkscreen layer of any device overlap, either one can be selected as the measurement layer.

[0024] In one implementation, adjacent devices on the same layer of the target device are determined based on the device location and the stacking structure in the design file. This includes: determining the target layer where each device is located based on the stacking structure; the target layer being either the top or bottom layer; and identifying devices located on the same layer as the target device and whose distance from the target device is less than a preset threshold, as adjacent devices on the same layer. This method of first filtering by layer and then by distance narrows the comparison range, eliminates devices on different layers and those that are far apart, reduces unnecessary calculations, and improves inspection efficiency.

[0025] S103. In the preset two-dimensional information structure, determine the target row index item corresponding to the device type of the target device and the target column index item corresponding to the device type of adjacent devices in the same layer; wherein, the row direction and column direction of the two-dimensional information structure both correspond to the recording of the device type set; the intersection position of any row index item and any column index item records the spacing reference parameters corresponding to the two device types in multiple relative directions respectively.

[0026] It should be noted that the two-dimensional information structure is a pre-established data structure, where both row and column indices correspond to the same set of device types. That is, the row and column directions record the same complete set of device types, and the order is consistent. The intersection of any row index item and any column index item records the spacing reference parameter between two device types. By using the device type as an index, the spacing reference parameter corresponding to the target device and its adjacent devices on the same layer can be directly located from the two-dimensional information structure without intermediate classification conversion, resulting in a short query path and facilitating fast system execution. The spacing reference parameter is a standard value used to determine whether the actual spacing is reasonable; its specific value is determined based on industry process capabilities.

[0027] In one implementation, the process of generating the two-dimensional information structure includes: configuring type identifiers for each device type according to device naming rules; arranging the type identifiers in a predetermined order to form a device type set; using the device type set as row and column indices, setting the spacing reference parameters for the two device types in the upward, downward, leftward, and rightward directions at the intersection of any row index item and any column index item, thus obtaining the two-dimensional information structure; the spacing reference parameters corresponding to any direction include: median spacing, lower limit spacing, and upper limit spacing. It can be seen that multiple relative directions include the upward, downward, leftward, and rightward directions. This integrates the device type definition and spacing standard values ​​into the same data structure, facilitating unified maintenance and querying. When a new device type is added, it is only necessary to add the type simultaneously in the row and column directions and supplement the spacing reference parameters at the corresponding intersection positions to complete the data expansion, simplifying maintenance.

[0028] S104. Read the target spacing reference parameter corresponding to the target relative direction from the intersection of the target row index item and the target column index item; the target relative direction is: the direction of adjacent devices in the same layer relative to the target device.

[0029] The target relative direction is determined based on the actual orientation of adjacent devices on the same layer relative to the target device. The intersection positions of the two-dimensional information structure are recorded with corresponding spacing reference parameters for each relative direction. Therefore, the spacing requirements for the same pair of devices can differ in different directions. By distinguishing the relative directions and reading the corresponding spacing reference parameters, the system can accommodate the differentiated spacing requirements of asymmetric devices in different directions, avoiding overly strict or lenient judgments in some directions due to the use of a single spacing value.

[0030] In one implementation, the target relative direction is determined as follows: First center coordinates of the target device and second center coordinates of adjacent devices on the same layer are obtained; based on the first and second center coordinates, the difference in horizontal and vertical coordinates between the adjacent devices and the target device are calculated; according to the magnitude of the difference in horizontal and vertical coordinates, the target relative direction is determined to be one of multiple relative directions. For example, when the difference in vertical coordinates is greater than the absolute value of the difference in horizontal coordinates and the difference in vertical coordinates is positive, the adjacent device on the same layer is determined to be above the target device; when the difference in horizontal coordinates is greater than the absolute value of the difference in vertical coordinates and the difference in horizontal coordinates is positive, the adjacent device on the same layer is determined to be to the right of the target device. Automatically determining the direction using coordinate differences avoids errors caused by specifying the direction.

[0031] S105. Compare the actual distance with the target distance reference parameters, and generate corresponding risk warning information based on the comparison results.

[0032] The target spacing benchmark parameters include the median spacing, lower spacing limit, and upper spacing limit. The actual spacing is compared to both the lower and upper spacing limits, and different levels of risk warning information are generated based on the range the actual spacing falls into. The median spacing can be displayed as a recommended distance value on the interface for personnel reference. By comparing the actual spacing with the standardized spacing benchmark parameters, the inspection results of the same layout by different personnel can be kept consistent, reducing judgment bias caused by differences in personnel experience.

[0033] In one example, the actual spacing is compared with the target spacing baseline parameter, and corresponding risk warning information is generated based on the comparison results. This includes: comparing the actual spacing with both the lower and upper spacing limits; if the actual spacing is less than the lower limit, an alarm risk warning is generated; if the actual spacing is not less than the lower limit but less than the upper limit, a warning risk warning is generated; if the actual spacing is not less than the upper limit, a no-risk warning is generated. Specifically, the alarm risk warning corresponds to a spacing below the minimum allowable distance, indicating a high risk of short circuits or mounting interference, requiring modification; the warning risk warning corresponds to a spacing between the minimum allowable distance and the safe distance, indicating that while the spacing meets the minimum requirements, it deviates from the recommended value, and confirmation is recommended; the no-risk warning corresponds to a spacing greater than or equal to the safe distance, indicating that the spacing meets the requirements and no action is needed. This allows for the categorization and display of spacing issues of different degrees, facilitating the priority handling of high-risk problems.

[0034] Accordingly, different risk warning messages can be displayed in different colors on the display interface. For example, alarm risk warning messages are displayed in red, early warning risk warning messages are displayed in yellow, and no risk warning messages are displayed in green or not displayed at all. By using color differentiation, personnel can intuitively identify the layout of problem points with different risk levels on the display interface, facilitating quick location and priority handling.

[0035] In one implementation, after generating corresponding risk warning information based on the comparison results, the process further includes: identifying and recording the tag number, coordinates, actual spacing, target spacing reference parameters, and abnormal location screenshots of the devices that violate spacing requirements, in order to generate an inspection report; wherein, the tag number is used to uniquely identify the device, such as C1, R1, U1, etc. Generating an inspection report allows for centralized display of abnormal information, facilitating personnel review and archiving. The abnormal location screenshots visually show which edge of a device exceeds the spacing limit with another device, allowing personnel to confirm before modification. After generating the inspection report, in response to the operation command on the target item in the inspection report, the system jumps to the corresponding location in the design file; thus, clicking on the abnormal item in the report directly locates the corresponding device position in the design file, eliminating the need for manual searching and reducing location time. After generating the inspection report, abnormal items marked with alarm risk warnings in the report can be identified as items requiring mandatory modification. In response to the modification instructions for these abnormal items, the corresponding actual spacing is remeasured and a secondary assessment is performed. If the secondary assessment result is still an alarm risk warning, a second alarm risk warning is output. If the secondary assessment result is a warning risk warning or no risk warning, the abnormal item is confirmed to have been repaired. This secondary assessment verifies whether the modified layout meets the spacing requirements, ensuring the accuracy of the inspection results.

[0036] In this embodiment, the two-dimensional information structure can be modified. Specifically, hierarchical permission management can be used to maintain the uniqueness and accuracy of modifications, avoiding confusion caused by accidental modifications by personnel. For example, modifications made under administrator privileges are persisted and take effect on all projects, while modifications made under user privileges only take effect in a single test and are automatically restored after a system restart. Therefore, in one implementation, in response to a modification operation with administrator privileges, the spacing reference parameter in the two-dimensional information structure is modified and persisted; in response to a modification operation with user privileges, the spacing reference parameter in the two-dimensional information structure is modified and marked as effective only once; in response to a system restart, the spacing reference parameter effective only once is restored to the value set by the administrator privileges.

[0037] Furthermore, the modification of the two-dimensional information structure also includes: in response to the operation of adding a new device type, adding the new device type to the end of both the row and column directions of the two-dimensional information structure, and recording the corresponding spacing reference parameters at the intersection position of the new device type. By maintaining data through appending rather than inserting at the end of the original two-dimensional information structure, the consistency of the device type arrangement order in the row and column directions can be maintained, avoiding query errors caused by disordered order.

[0038] As can be seen, the spacing inspection method provided in this embodiment, by automatically extracting component information, identifying adjacent components on the same layer, measuring the actual spacing, querying and comparing the spacing reference parameters in the two-dimensional information structure, can reduce the subjective influence of manual inspection and ensure consistent inspection results for the same layout by different personnel. Through hierarchical risk warnings, inspection report generation, secondary judgment, and access control, it can adapt to different design needs and ensure the accuracy and maintainability of inspection results. For PCB design files with a large number of components, it can significantly shorten the inspection cycle and improve inspection efficiency.

[0039] The following describes an automatic layout inspection and control system that presets component layout spacing requirements. When layout personnel complete the component layout, they upload the completed layout design data to the system. The system automatically identifies the layout layers, locates the component's body layer and attribute layer, confirms the component type based on its attributes, and then measures the layout gap between the component and surrounding components of different types according to the component spacing requirements in the Bill of Materials (BOM). Based on the measurement results, the system classifies the risk level and displays the problematic layout points of different risk levels to the layout personnel, enabling them to intuitively and accurately locate and modify abnormal locations without needing to perform a full component inspection against the BOM. The system includes a logic control unit equipped with a computer capable of uploading layout design files and running the detection system. The system also includes a background control system that sets the median design requirement for the layout spacing between each type of component and adjacent components of different types, according to the layout component naming rules and component spacing requirements. It also allows setting upper and lower limits for the spacing based on the median value, and personnel can fine-tune these settings according to specific product requirements.

[0040] A material type list is required in the system backend to serve as the basis for the system's component spacing check. This data includes the following: All component types and material types that may be used during the layout process are assigned a unique name or code according to the naming rules on the board in the layout design, so as to distinguish all material types used in the design process. This list needs to cover all material types that need to be used.

[0041] The median table for material spacing control requirements records the relative spacing requirements between each type of component and other components in the design. It defines the spacing requirements for each type of component, serving as the numerical basis for the software system's background judgment on the rationality of layout spacing. It also acts as the benchmark for setting the upper and lower limits of material spacing. The setting of this median table must be determined through discussion among all relevant designers.

[0042] The principle for determining the median spacing between components is that it is not based on the limits of a particular project or existing projects, but rather on the current process capabilities of the SMT (Surface Mount Technology) industry. Simply relying on the capabilities of a particular project or existing projects would require frequent and extensive adjustments when encountering special projects or extreme design requirements, thus affecting the system's detection performance. Taking the spacing between 0201 resistors as an example, it is necessary to investigate the printing capabilities and placement accuracy of the placement equipment in the factory, as well as the forming accuracy of the solder paste used in the factory's soldering production, to determine the reasonable range of achievable accuracy.

[0043] The median table is maintained and revised as follows: The top row of each horizontal row contains the material number code, used by the system to identify materials. The second row contains the Chinese material type identifier. This identifier has no practical function in the system but is used to help personnel understand the material type represented by each code during form maintenance, avoiding system maintenance errors caused by inconsistent understanding of material types among different personnel, which could affect system judgment. The third row contains the English material type identifier. This column represents the definition of material attributes by personnel during layout design and must be consistent with the material attributes and descriptions set when the material was created. Subsequent layout design drawings and the system's identification of material types will be based on this row for material type classification. Furthermore, subsequent spacing control and alarm control will also be based on this row.

[0044] The median data is explained as follows: The first column of the vertical column is the material number code, which is the same as the first row of the horizontal column, used by the system to identify materials. The second column of the vertical column is the English identifier of the material type, which is the same as the third row of the horizontal column. Materials with the same English identifier must maintain consistent relative positions in both the horizontal and vertical columns. That is, if the material in the first column of the horizontal column is device 01005, the material in the first row of the vertical column is also device 01005, and so on for subsequent material maintenance. The median spacing between different types of materials is determined by drawing a vertical line downwards for one type of material in the horizontal column and a horizontal line for another type of material in the vertical column; the number at the intersection of these two lines is the median spacing between the two types of materials.

[0045] The median table maintenance rules are as follows: if new materials are added later, the same type of material must be added to both the horizontal row and the vertical column, and the maintenance order must follow the order of this table from top to bottom. It is not allowed to disrupt the existing order when inserting material types.

[0046] In one example, the median table corresponding to the material type can be set with reference to Table 1.

[0047] Table 1

[0048] Material types maintain a consistent order both horizontally and vertically, but the corresponding median spacing can be adjusted based on production technology advancements and actual defect rates during actual use. Data adjustments are performed by designated personnel with administrator privileges, and the adjusted values ​​must be decided through discussion among relevant personnel. A single user can modify basic data during a product testing process with user privileges; this modification only takes effect for that single test and reverts to the administrator-set values ​​after a system restart. This setting maintains the uniqueness and accuracy of system parameters, preventing system instability due to accidental user modifications.

[0049] Once all materials in the material type list and material spacing control requirements table are entered into the system, a device spacing overview table is generated, such as... Figure 2 As shown in the device spacing table, system personnel need to further maintain the relative positional relationship between device 1 and its counterpart device 2, that is, the upper limit, middle value, and lower limit of the distance required when device 2 is above, below, to the left, and to the right of device 1.

[0050] Once the data maintenance is complete, the basic data for system operation is considered maintained. Frequent changes to the system's backend basic median data are not permitted; a change frequency of once a year or once every two years is generally reasonable. However, the addition or deletion of material types can be performed based on actual circumstances and is not subject to this frequency restriction.

[0051] After completing a new product layout design, the layout engineer exports a BRD file. Upon importing the file into the system, the system automatically adapts to the BRD file format and differentiates the design data according to the layout's layer stacking, distinguishing SST (silkscreen layer), SPT (stencil layer), and SMT (solder mask layer) based on the actual layer stacking. The BRD file automatically displays the layers after import, as shown in the image. Figure 3 As shown.

[0052] Since SPT represents the actual mounting area of ​​a device, while SST represents the silkscreen outline, some devices, due to their unique shapes, have silkscreen outlines larger than their pads (solder pads), meaning the SST range is larger than the SPT. Therefore, the system automatically selects the larger of the two ranges, SPT and SST, as the device spacing measurement layer. The system automatically measures the distance from the edge of the larger outline layer of each device to its adjacent devices, while simultaneously calling the device library to identify the type of the device and its neighbors. Then, it compares the measured spacing values ​​with the upper, middle, and lower limits of the spacing requirements for both device types in the system's maintained device spacing overview table. If the SPT and SST of some devices overlap, the system automatically selects any one of these layers as the measurement layer for spacing measurement.

[0053] The system's judgment criteria are as follows: If the measured value is greater than or equal to the upper limit of the spacing, the system automatically assumes the spacing meets the design requirements, and the judgment result is automatically displayed as "OK" and hidden. If the measured result is less than the upper limit but greater than the lower limit, the system determines that the spacing is risky and displays it in yellow, reminding personnel to confirm again. If the measured result is less than the lower limit, the system marks the spacing between the two components in red, reminding the layout personnel to modify the layout. At the same time, the system generates a screenshot of the component spacing not meeting the design requirements, prompting personnel to confirm which edge of the component exceeds the spacing standard with another type of material, facilitating confirmation before modification. The system captures images to show the layout personnel which component spacing is at risk (yellow) and which component spacing does not meet the requirements (red), and outputs an Excel report detailing the measurement results of the abnormal data and the names of the components. Specifically, when the distance is less than or equal to the lower limit, the system displays it in red in the judgment result on the interactive interface, indicating that the component spacing needs to be adjusted and re-judged. When the distance is the median value, the system displays it in yellow, indicating that the distance meets the minimum requirements, but should be adjusted as much as possible if space allows. When the distance is greater than or equal to the upper limit, the system displays green, indicating that the distance is safe and does not require secondary verification by personnel. The corresponding risk warnings and upper / lower limit settings page can be found in [reference needed]. Figure 4 . Figure 4 The illustrated software interface mainly includes a basic parameter setting area at the top, a function control area in the middle, and a data display area at the bottom.

[0054] After the system completes the measurement, it can export an excel report of the Layout Check Report with one click. This report details the location of the anomaly, the image of the anomaly, and the data measurement results of the anomalous points. At the same time, the report gives color prompts according to the severity of the measured data, which are yellow or red. Yellow suggests confirmation, and red suggests modification. The Layout personnel give the confirmation result of the corresponding anomaly based on the measured data and the images of the anomalous points in the report. If it is confirmed to continue implementing according to the existing scheme, a written description shall be provided; if modification is required, corresponding modifications shall be made in the design software. The modified layout design file needs to undergo secondary software analysis and identification. The images of the anomalous points are as Figure 5 shown in Figure 5 , where ①, ② and ③ are anomalous points.

[0055] The red results displayed in the software report are the final results determined based on the upper and lower limits of the devices set in the device spacing list. The device spacing list is a consensus reached by the department, and in principle, individual projects are not allowed to make secondary revisions. Therefore, unless the system identifies and determines an anomaly, all red alarms in the report must be modified, and the secondary detection and determination after modification shall at least present a yellow color or no display, so as to prove that the detection result meets the design requirements, and the layout check of this project is qualified before subsequent other work can be carried out. The software report can refer to Figure 6 .

[0056] It can be seen that the systematic method for automatically checking the device spacing during the layout process can accurately identify abnormal layout spacing conditions and display them in a graded manner, which facilitates the layout personnel to quickly confirm the layout spacing and avoids the personnel checking one by one according to the BOM. The working hours for personnel to check according to the BOM and for personnel in the same position to conduct secondary recheck are reduced from three to five days to be completed within one day, thereby greatly saving labor costs. Changing from manual inspection by personnel to automatic system inspection can effectively avoid the difference in inspection results caused by differences in personnel skills and reduce omissions in manual inspection. The upper and lower limits of the devices set in the device spacing list are set after review by all relevant personnel in the department, and the system uses this to judge the spacing, which can effectively avoid differences in different personnel's acceptance and understanding of device spacing, achieve unified standards and consistent results, and effectively manage the design standardization of layout personnel. The device spacing sets the distance requirements from the surrounding devices in the four directions of up, down, left, and right of the device respectively, which can effectively reduce design bottlenecks and improve the flexibility of design layout. The system opens administrator rights and user rights, and the administrator rights are set and operated in the background by a dedicated person, which can effectively avoid the risks brought by personnel misoperation.

The measurement module is used to determine the adjacent devices in the same layer of the target device based on the device position of the target device and the stacking structure in the design file, and to measure the actual distance between the target device and the adjacent devices in the same layer. The determination module is used to determine the target row index item corresponding to the device type of the target device and the target column index item corresponding to the device type of adjacent devices in the same layer in a preset two-dimensional information structure; wherein, the row direction and column direction of the two-dimensional information structure correspond to the recording of the device type set; the intersection position of any row index item and any column index item records the spacing reference parameters corresponding to the two device types in multiple relative directions respectively; The reading module is used to read the target spacing reference parameter corresponding to the target relative direction from the intersection of the target row index item and the target column index item; the target relative direction is: the direction of adjacent devices in the same layer relative to the target device; The comparison module is used to compare the actual distance with the target distance benchmark parameters and generate corresponding risk warning information based on the comparison results.

[0059] In one implementation, the process of generating a two-dimensional information structure includes: configuring type identifiers for each device type according to device naming rules; arranging the type identifiers in a predetermined order to form a device type set; using the device type set as row and column indices, setting the spacing reference parameters corresponding to the two device types in the up, down, left, and right directions at the intersection of any row index item and any column index item, to obtain a two-dimensional information structure; the spacing reference parameters corresponding to any direction include: median spacing, lower spacing limit, and upper spacing limit.

[0062] In one implementation, the target relative direction is determined by: obtaining the first center coordinates of the target device and the second center coordinates of adjacent devices on the same layer; calculating the difference in horizontal coordinates and vertical coordinates of adjacent devices on the same layer relative to the target device based on the first center coordinates and the second center coordinates; and determining the target relative direction as one of multiple relative directions according to the relationship between the magnitude of the difference in horizontal coordinates and the difference in vertical coordinates.

[0063] In one implementation, the target spacing reference parameters include: a lower spacing limit and a higher spacing limit; correspondingly, the comparison module is used to: compare the actual spacing with the lower spacing limit and the higher spacing limit respectively; if the actual spacing is less than the lower spacing limit, an alarm risk warning message is generated; if the actual spacing is not less than the lower spacing limit and is less than the higher spacing limit, a warning risk warning message is generated; if the actual spacing is not less than the higher spacing limit, a no-risk warning message is generated.
