Description

Technical Field

[0001] This application relates to the field of electronic design automation technology, and in particular to a chip layout loading method, apparatus, device and medium. Background Technology

[0002] With the rapid advancement of semiconductor manufacturing technology, in order to meet the market's demand for higher computing power and stronger functional integration in smart devices, the design scale of integrated circuits has continued to expand. This has led to a dramatic increase in the number of electronic devices integrated on a chip, and the interconnections between these devices have become more complex, resulting in very large-scale complex integrated circuits (VLSI). In the design and analysis process of integrated circuits, EDA tools are typically used to load the full data of the chip layout. After full loading, the layout is rendered and displayed for users to design the integrated circuit. However, for VLSI, the time required to load the layout data is significantly extended, and the memory footprint also increases significantly. This results in noticeable lag during user interaction with the layout, limiting the design efficiency of integrated circuits.

[0003] Therefore, there is an urgent need to propose a technical solution that can improve the loading efficiency of chip layout and enhance the smoothness of layout interaction. Summary of the Invention

[0004] This application provides a chip layout loading method, apparatus, device, and medium.

The chip layout loading method proposed in this application, when the current scaling range of the target layout is large, after the user performs an entity selection operation, draws multi-level graphic thumbnails based on the graphic data of the selection group corresponding to the entity selection operation; according to the scaling requirements of the current scaling range, the target graphic thumbnail is selected from the multi-level graphic thumbnails, and the target graphic thumbnail is drawn according to the current scaling range to obtain the loading view of the target layout corresponding to the entity selection operation.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] With the rapid advancement of semiconductor manufacturing technology, in order to meet the market's demand for higher computing power and stronger functional integration in smart devices, the design scale of integrated circuits has continued to expand. This has led to a dramatic increase in the number of electronic devices integrated on a chip, and the interconnections between these devices have become more complex, resulting in very large-scale complex integrated circuits (VLSI). In the design and analysis process of integrated circuits, it is usually necessary to load the full data of the chip layout using EDA tools. After full loading, the chip layout is rendered and displayed for users to design the integrated circuit. However, for VLSI, the time required to load the layout data is significantly extended, and the memory footprint also increases significantly. This leads to noticeable lag in the user's interaction with the layout, limiting the design efficiency of integrated circuits. Therefore, there is an urgent need to propose a technical solution that can improve the loading efficiency of chip layouts and enhance the smoothness of layout interaction.

[0020] To address the aforementioned issues, this application provides a chip layout loading method, apparatus, device, and medium. When the number of sub-regions in the current scaling range of the target layout exceeds a preset range threshold, in response to a user's entity selection operation, a multi-level graphic thumbnail of the selection group is drawn based on the graphic data in the selection group corresponding to the entity selection operation. The sub-regions are obtained by meshing the target layout. Based on the scaling requirements of the current scaling range, a target graphic thumbnail is selected from the multi-level graphic thumbnails, and the target graphic thumbnail is range-adapted and drawn according to the current scaling range to obtain a loading view of the selected group corresponding to the target layout.

[0021] The chip layout loading method provided in this application, when the current scaling range of the target layout is large, after the user performs an entity selection operation, draws a multi-level graphic thumbnail based on the graphic data of the selection group corresponding to the entity selection operation; according to the scaling requirements of the current scaling range, selects the target graphic thumbnail from the multi-level graphic thumbnails, and performs range adaptation drawing on the target graphic thumbnail according to the current scaling range, thereby obtaining the loading view of the entity selection operation corresponding to the target layout.

[0022] Compared with related technologies, this application groups and categorizes graphic data belonging to different entity objects and draws bitmaps separately. This allows for targeted drawing based on the graphic data corresponding to the entity objects when the user selects some entity objects for display. This effectively reduces the memory resource requirements for loading target drawings and improves the loading efficiency and smoothness of interaction of target drawings.

[0023] Furthermore, this application also optimizes the loading efficiency of the target map by dividing the target map into data segments and processing the segmented sub-regions separately, thereby enabling on-demand loading of the target map according to the current scaling range.

[0024] According to an embodiment of this application, a chip layout loading method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0025] Reference Figure 1 As shown, this embodiment provides a chip layout loading method, which includes: S100. If the number of sub-regions in the current zoom range of the target map exceeds a preset range threshold, in response to the user's entity selection operation, draw a multi-level graphic thumbnail of the selection group according to the graphic data in the selection group corresponding to the entity selection operation; wherein, the sub-region is obtained by gridding the target map.

[0026] S200. Based on the scaling requirements of the current scaling range, select the target graphic thumbnail from the multi-level graphic thumbnails, and perform range adaptation drawing on the target graphic thumbnail according to the current scaling range to obtain the loading view of the selected group corresponding to the target map.

[0027] The target layout can be the chip layout that the user needs to display and process. The graphic data (Layout) of the target layout is stored in the Design database. The graphic data can include instance data, layout graphics (Shape), and pin graphics (PinShape). The graphic data corresponds to coordinate (Box) information in the target layout.

[0028] Specifically, the target layout is divided into multiple regions (bins) according to a preset size, and each region corresponds to graphic data within a preset coordinate range in the target layout. For very large-scale integrated circuits, the number of graphic data points contained in each region is still relatively large. To further improve the loading efficiency of the target layout, this embodiment further divides the multiple regions into multiple sub-regions (subbins). For example, the division of regions into sub-regions can be based on the number of graphic data points in each sub-region not exceeding a preset data threshold, which can be 100,000. It is understood that by dividing the target layout into multiple sub-regions, bitmaps can be drawn separately in each sub-region to obtain a complete graphic thumbnail, thereby improving the loading efficiency of the target layout.

[0029] Furthermore, if the number of sub-regions within the current zoom range of the target map exceeds a preset range threshold, the target map will have a large display area and show a lot of data. If the view is still drawn using the actual data of the target map, the view loading time will be too long, causing a significant delay in the user's graphical interface. This manifests as lag during user interaction with the graphical interface, affecting the user's processing of the target map. For example, the preset range threshold could be that the current zoom range contains four sub-regions.

[0030] When loading the target layout, users can select entities of interest using the entity selection operation to primarily display these entities in the loading view. It should be noted that entity objects can include physical layer entities and network entities, corresponding to the graphical data in the target layout. Physical layer entities represent the graphical data of the target layout at the corresponding physical layer, while network entities represent any graphical data with electrical connections on the target layout. The entity selection operation allows users to select one or more entity objects from the target layout based on their actual analysis or display needs, using the selected entity objects as the data basis for drawing graphical thumbnails.

[0031] In some embodiments, users can select entities through a graphical user interface by checking or selecting the corresponding entity objects. (See also...) Figure 2a As shown, Figure 2a The document displays multiple physical layer entities in the target layout. Users can select a physical layer entity by clicking the checkbox corresponding to that entity. (See reference...) Figure 2b As shown, Figure 2b The document displays multiple network entities in the target map. Users can select a network entity by clicking the checkbox corresponding to that entity. It's understood that an entity group can be a combination of any physical layer entity and any network entity. When both network and physical layer entities are selected simultaneously, the selected network entities and their corresponding entity groups can be used as the selection groups.

[0032] In response to a user's entity selection operation, a selection group is formed based on the entity objects corresponding to the selection operation. Based on the correspondence between the entity objects in this selection group and the graphic data, the corresponding graphic data is selected from the target layout. Thumbnails are then drawn based on this graphic data to obtain multi-level graphic thumbnails corresponding to the selection group in the target layout. It can be understood that the process of drawing multi-level graphic thumbnails may include: performing bitmap coordinate transformation on the coordinate information of the graphic data corresponding to the selection group in the target layout to obtain bitmap coordinates; drawing bitmaps for each sub-region based on the graphic data and bitmap coordinates corresponding to the selection group to obtain sub-region graphic bitmaps for each sub-region; merging the sub-region graphic bitmaps of all sub-regions at full size based on the relative position of each sub-region in the target layout to obtain a full-size combined bitmap of the target layout corresponding to the selection group; and performing proportional thumbnail mapping on the full-size combined bitmap according to a preset scaling ratio to obtain multi-level graphic thumbnails. The multi-level graphic thumbnails are arranged sequentially according to their corresponding scaling ratios and output to the same file. For example, the preset scaling ratio may include a series of sizes such as full size, 9 / 10 and 8 / 10, and the scaling ratio difference between adjacent level graphic thumbnails may be the same or different, and each level graphic thumbnail contains all the valid information of the full-size combined bitmap.

[0033] It should be noted that users can perform multiple entity selection operations during the processing of the target map. In this embodiment, when the user performs an entity selection operation, the multi-level graphic thumbnails are redrawn in response to the entity selection operation, realizing targeted drawing of graphic data. This not only improves the view drawing efficiency and reduces resource consumption in each thumbnail drawing, but also optimizes the display effect of the selected entity objects, providing convenience for the process of processing the target map.

[0034] When the target map is loaded for the first time, before the user has selected any entities, the target map is displayed globally by default. After obtaining the multi-level graphic thumbnails of the target map, the user graphical interface used to display the loading view first loads the global information of the target map and reads the thumbnail with the smallest scaling ratio from the multi-level graphic thumbnails. This thumbnail is then displayed in the user graphical interface with a preset scaling range, resulting in the loading view of the target map in global display mode, such as... Figure 3a As shown. It is understandable that loading the thumbnail with the smallest scaling requires fewer resources and takes less time, which can enable the user's graphical interface to start quickly and improve the display efficiency of the target map.

[0035] Furthermore, the target map has a current zoom range on the user's graphical interface, including its display position and zoom level. The display position represents the area of ​​the target map displayed on the user's graphical interface, and the zoom level represents the degree of scaling of the displayed area. The current zoom range can be a preset range or determined based on the user's view zooming operation. After the user zooms the loaded view, if the relative numerical relationship between the number of sub-regions within the current zoom range and the preset range threshold changes—for example, if the number of sub-regions within the current zoom range changes from exceeding the preset range threshold to not exceeding it, or vice versa—the loaded view can be redrawn based on the current zoom range after the view zooming operation.

[0036] Based on the current zoom range required to display the target image, all thumbnails in the multi-level graphic thumbnail image hierarchy are traversed in ascending order of resolution. The thumbnail whose resolution meets the zoom requirements of the current zoom range is selected as the target graphic thumbnail. For the target graphic thumbnail, a region is cropped according to the area corresponding to the current zoom range to obtain a loading view that matches the size of the current zoom range for display on the user's graphical interface. For example, the loading view can be as follows: Figure 3b As shown.

[0037] The chip layout loading method provided in this embodiment, when the current scaling range of the target layout is large, after the user performs an entity selection operation, draws a multi-level graphic thumbnail based on the graphic data of the selection group corresponding to the entity selection operation; according to the scaling requirements of the current scaling range, the target graphic thumbnail is selected from the multi-level graphic thumbnails, and the target graphic thumbnail is drawn according to the current scaling range to obtain the loading view of the entity selection operation corresponding to the target layout.

[0038] Compared with related technologies, this application groups and categorizes graphic data belonging to different entity objects and draws bitmaps separately. This allows for targeted drawing based on the graphic data corresponding to the entity objects when the user selects some entity objects for display. This effectively reduces the memory resource requirements for loading target drawings and improves the loading efficiency and smoothness of interaction of target drawings.

[0039] Furthermore, this application also optimizes the loading efficiency of the target map by dividing the target map into data segments and processing the segmented sub-regions separately, thereby enabling on-demand loading of the target map according to the current scaling range.

[0040] Reference Figure 4As shown, in one embodiment of this application, the target layout includes physical layer entities and network entities, which are arranged and combined to form entity groups. When performing power integrity analysis based on the target layout, a multi-level graphical thumbnail of the selected group is drawn based on the graphical data in the selected group corresponding to the entity selection operation, including: S110. Obtain the group bitmap corresponding to the selected group, and the global bitmap corresponding to the physical layer entities in the selected group; wherein, the group bitmap is obtained by drawing bitmaps based on the graphic data corresponding to each entity group in the target layout, and the global bitmap is obtained by drawing bitmaps based on the graphic data corresponding to each physical layer entity in the target layout.

[0041] S120. Overlay the grouped bitmaps to obtain a grouped overlay bitmap; overlay the global bitmaps to obtain a global overlay bitmap.

[0042] S130. Perform overlay drawing based on the grouped overlay bitmap and the global overlay bitmap, and scale the overlay drawing result to obtain a multi-level graphic thumbnail.

[0043] Power integrity analysis (PG Flow) is a process of verifying the power supply network of a physical design represented by a target layout, ensuring that the physical design can stably and reliably power the entire chip. The specific object of power integrity analysis is the power ground network (PGNet) in the physical design, representing the power supply topology, power connectivity, and electrical performance of the physical design. It can consist of one or more network entities in the target layout.

[0044] Specifically, when a user selects an entity, they can check one or more target entities in the user's graphical interface for partial display. Target entities can be of the same type or different types, and can be physical layer entities, network entities, or a combination of both. A target entity can correspond to multiple entity groups. For the target entity selected by the user through the entity selection operation, the group bitmap corresponding to the same physical layer entities and network entities as the target entity is obtained, and the global bitmap corresponding to the same physical layer entities as the target entity is also obtained.

[0045] Furthermore, when the target entities selected in the entity selection operation include more than one network entity, the group bitmaps corresponding to each network entity in the target entity are overlaid to obtain a group overlaid bitmap. Similarly, when the target entities selected in the entity selection operation include more than one physical layer entity, the group bitmaps corresponding to each physical layer entity in the target entity are overlaid to obtain a group overlaid bitmap. It can be understood that when the target entities selected in the entity selection operation include both more than one network entity and more than one physical layer entity, the group bitmaps corresponding to each network entity and each physical layer entity in the target entity are overlaid to obtain a group overlaid bitmap. Likewise, when the target entities selected in the entity selection operation include more than one physical layer entity, the global bitmaps corresponding to each physical layer entity in the target entity are overlaid to obtain a global overlaid bitmap.

[0046] Furthermore, grouped overlay bitmaps are drawn on top of the global overlay bitmap to highlight the target entity selected by the user through entity selection, resulting in an overlay drawing result. The overlay drawing result is then scaled down according to a preset scaling ratio to obtain multi-level graphic thumbnails corresponding to the selected groups. It is understood that in this embodiment, the grouped bitmap and global bitmap can be pre-acquired before loading the target layout and retrieved during the loading process to quickly generate graphic thumbnails, thereby significantly improving the loading efficiency of the target layout and reducing response stuttering during user interaction with the layout, thus improving the smoothness of the target drawing interaction.

[0047] Reference Figure 5 As shown, in one embodiment of this application, the grouped bitmap is obtained in the following manner: S142. In any sub-region of the target map, perform grouping statistics based on the physical layer entities and network entities contained in any sub-region to obtain the region grouping of any sub-region.

[0048] S144. For any region group, draw a bitmap based on the graphic data of any region group to obtain a region group bitmap corresponding to any region group for any sub-region.

[0049] S146. Overlay the bitmaps of all sub-regions to obtain the bitmap corresponding to any region group.

[0050] Specifically, within each sub-region, graphical data can correspond to the same or different entity objects. The entity information of the graphical data can be the correspondence between the graphical data and the entity objects. When the entity objects include physical layer entities and network entities, the entity information includes physical layer information and network information. The physical layer information indicates which physical layer entity the graphical data is drawn on, and the network information indicates which network entities the graphical data constitutes. For any sub-region, any physical layer information and any network information are combined to obtain a layer-network information combination. Based on this layer-network information combination, the graphical data of that sub-region is grouped and statistically analyzed to obtain the regional grouping of the graphical data for that sub-region.

[0051] The following example illustrates the grouping and statistics of graphic data. Any sub-region contains graphic data 1, 2, 3, and 4, where graphic data 1, 3, and 4 are drawn on a first physical layer entity, and graphic data 2 is drawn on a second physical layer entity. Graphic data 1 and 4 are in the first network entity, and graphic data 2 and 3 are in the second network entity. In this case, the layer network information obtained through information combination can include data drawn on the first physical layer entity and belonging to the first network entity, data drawn on the first physical layer entity and belonging to the second network entity, and data drawn on the second physical layer entity and belonging to the second network entity. It can be seen that graphic data 1 and 4 meet the criteria of being drawn on the first physical layer entity and belonging to the first network entity, and are grouped into the first entity group; graphic data 3 meets the criteria of being drawn on the first physical layer entity and belonging to the second network entity, and is grouped into the second entity group; graphic data 2 meets the criteria of being drawn on the second physical layer entity and belonging to the second network entity, and is grouped into the third entity group.

[0052] Furthermore, for any region group within any sub-region, a bitmap is drawn based on the graphic data of that region group to obtain a region grouping bitmap corresponding to that sub-region. Similarly, bitmaps are drawn in all sub-regions based on the graphic data corresponding to that region group to obtain a region grouping bitmap for each sub-region. Based on the relative positional relationship between the sub-regions, the region grouping bitmaps of all sub-regions are stitched together and superimposed to obtain the grouping bitmap of that region group within the complete region.

[0053] Reference Figure 6 As shown, in one embodiment of this application, the global bitmap is obtained in the following manner: S152. In any sub-region of the target map, group and count the physical layer entities and network entities contained in the sub-region to obtain the region group of the sub-region; merge the region groups corresponding to the same physical layer entity to obtain the physical layer group of the sub-region.

[0054] S154. For any physical layer group, a bitmap is drawn based on the graphic data of any physical layer group to obtain the physical layer group bitmap corresponding to any physical layer group for any sub-region.

[0055] S156. Concatenate and overlay the physical layer group bitmaps of all sub-regions to obtain the global bitmap corresponding to any physical layer group.

[0056] Specifically, for any sub-region, any physical layer information and any network information are combined to obtain a layer-network information combination. Based on the layer-network information combination, the graphic data of any sub-region is grouped and statistically analyzed to obtain regional groups for the graphic data of that sub-region. Based on the physical layer information of each regional group, regional groups with the same physical layer information are merged to obtain physical layer groups corresponding to the same physical layer entities.

[0057] Furthermore, for any physical layer group within any sub-region, a bitmap is drawn based on the graphic data of that physical layer group to obtain a physical layer group bitmap corresponding to that physical layer group for that sub-region. Similarly, bitmaps are drawn in all sub-regions based on the graphic data corresponding to that physical layer group to obtain a physical layer group bitmap for each sub-region corresponding to that physical layer group. Based on the relative positional relationship between the sub-regions, the regional group bitmaps of all sub-regions are stitched together and superimposed to obtain a global bitmap of that physical layer group in the complete region.

[0058] Reference Figure 7 As shown, in one embodiment of this application, the target layout includes physical layer entities and network entities, which are arranged and combined to form entity groups. When performing signal flow analysis based on the target layout, a multi-level graphical thumbnail of the selected group is drawn based on the graphical data in the selected group corresponding to the entity selection operation, including: S160. Obtain the global bitmap corresponding to the physical layer entities in the selected group; wherein, the global bitmap is obtained by drawing the bitmap based on the graphic data corresponding to each physical layer entity in the target layout.

[0059] S170. For network entities in the selected group, extract data based on file offset information to obtain the full network data.

[0060] S180. Based on the full network data, perform network overlay drawing on the global bitmap to obtain a network overlay bitmap, and scale the network overlay bitmap to obtain a multi-level graphic thumbnail.

[0061] Signal flow analysis is a process of verifying the logic signal transmission of a physical design represented by a target layout, ensuring that logic signals can be transmitted correctly and without distortion within the physical design. The specific object of signal flow analysis is the signal net in the physical design, representing the signal transmission path, which can consist of one or more network entities in the target layout. The user graphical interface may also include a selection interface for signal nets, allowing users to select one or more signal nets for targeted analysis. (See reference...) Figure 8 As shown, the user graphical interface can also include a selection interface for signal networks. In this interface, users can select one or more signal networks for targeted analysis. Compared to power integrity analysis, the number of signal networks in signal flow analysis far exceeds the number of power and ground networks. If the graphical data is classified and statistically analyzed based on physical layer and network information, it will result in an excessive number of entity groups, leading to excessively large bitmap file sizes and thus consuming too much memory.

[0062] Specifically, based on the target entity selected by the user through the entity selection operation, a global bitmap corresponding to the same physical layer entity as the target entity is obtained. If the target entity selected by the entity selection operation includes more than one physical layer entity, the global bitmaps corresponding to each physical layer entity in the target entity are overlaid and drawn to obtain a global overlay bitmap.

[0063] It should be noted that in this embodiment, the graphical data corresponding to the network entities in the selected groups are located and stored in each sub-region in the form of file offsets. Based on the file offset information, the target entity can be quickly loaded and drawn from the sub-region. Before performing signal flow analysis, each sub-region is pre-parsed to obtain the file offset information of each entity object in the sub-region. The file offset information of the same entity object in different sub-regions is integrated to obtain the integrated file of the file offset of the same entity object and output it.

[0064] Furthermore, for the network entities selected by the user through the entity selection operation, data is extracted from the integrated files based on their corresponding file offsets to obtain the full network data for each network entity. Based on the global overlay bitmap, the network entities selected by the user are overlaid and drawn on the global overlay bitmap according to the full network data, resulting in a network overlay bitmap. The network overlay bitmap is then scaled according to a preset scaling ratio to obtain multi-level graphic thumbnails corresponding to the selected groups. These multi-level graphic thumbnails are arranged sequentially according to their corresponding scaling ratios and output to the same file.

[0065] Understandably, the network entities selected by the user can be enhanced in the network overlay bitmap based on the overlay operation. In the resulting multi-level graphic thumbnail, these network entities are more easily noticed by the user than other network entities, which optimizes the display effect of network entities and makes it easier for users to quickly find the signal network to be analyzed in signal flow analysis, thereby improving the efficiency of signal flow analysis.

[0066] As one embodiment of this application, the target layout includes physical layer entities and network entities; when the user does not select any network entity through an entity selection operation, a multi-level graphical thumbnail of the selection group is drawn based on the graphical data in the selection group corresponding to the entity selection operation, including: S190. For any physical layer entity selected by the entity selection operation, perform bitmap drawing and image scaling based on the graphic data of all network entities corresponding to any physical layer entity to obtain a multi-level graphic thumbnail.

[0067] Specifically, for any sub-region, any physical layer information and any network information are combined to obtain a layer-network information combination. Based on the layer-network information combination, the graphic data of any sub-region is grouped and statistically analyzed to obtain regional groups for the graphic data of that sub-region. Based on the physical layer information of each regional group, regional groups with the same physical layer information are merged to obtain physical layer groups corresponding to the same physical layer entities.

[0068] Furthermore, when the user does not select any network entity through the entity selection operation, the user's graphical interface displays all network objects by default. For any physical layer entity selected by the user through the entity selection operation, a bitmap is drawn based on the graphical data of the physical layer group corresponding to that physical layer entity, resulting in a global bitmap corresponding to that physical layer entity. If the target entities selected by the entity selection operation include more than one physical layer entity, the global bitmaps corresponding to all physical layer entities selected by the user are overlaid to obtain a global overlay bitmap. For the global overlay bitmap, a scaling mapping is performed on the global overlay bitmap according to a preset scaling ratio to obtain multi-level graphic thumbnails.

[0069] It should be noted that when the user does not select any physical layer entity through the entity selection operation, the physical layer entity corresponding to the graphic data used for bitmap drawing and image scaling can be any physical layer entity or any preset physical layer entity.

[0070] Reference Figure 9 As shown in one embodiment of this application, the method further includes: S310. If the number of sub-regions in the current scaling range does not exceed the preset range threshold, extract the layout data of the sub-regions contained in the current scaling range to obtain the actual data of the sub-regions.

[0071] S320. Draw the view based on the actual data of the sub-region to obtain the loaded view.

[0072] Specifically, when the number of sub-regions in the current zoom range of the target map is less than the preset range threshold, the display range of the target map is small and less data is displayed. At this time, the time consumed by drawing the view using the real data of the target map is short, and the view quality can be effectively improved, so that each entity object in the loaded view can be selected, making it easier for users to process and analyze the target map.

[0073] Furthermore, map data is extracted from the sub-regions included in the current zoom range to obtain the actual data of the graphics data in these sub-regions, thus obtaining the actual sub-region data. It can be understood that the actual sub-region data can be data used to describe the actual attributes of the graphics data, and these actual attributes can include, but are not limited to, attributes such as the coordinates, shape, and hierarchical structure of the graphics data.

[0074] Furthermore, based on the selection group corresponding to the entity selection operation, the graphic data corresponding to the selection group is filtered from the real data of the sub-region to obtain the grouped graphic data corresponding to the selection group. After obtaining the grouped graphic data, a bitmap is drawn based on the grouped graphic data to obtain the loading view. It can be understood that the loading view drawn using the real data of the sub-region can also be scaled and cropped according to the current zoom range to obtain a view suitable for the current zoom range for display. For example, the loading view obtained in this embodiment can refer to... Figure 10 As shown, in this embodiment, the view is directly drawn based on the actual data of the target map to obtain the loaded view, thereby improving the accuracy of the loaded view while ensuring the loading efficiency of the target view.

[0075] In some embodiments, sub-regions within the current zoom range form a visualization queue, which is stored in the memory of the user's graphical interface. The user's graphical interface loads sub-regions from the visualization queue for view rendering. When the user performs a view movement operation or a view zoom operation within a preset range threshold, the sub-regions within the current zoom range are added to the visualization queue after the operation. To maintain the visualization queue within a preset queue size, sub-regions at the top of the queue can be eliminated, keeping the queue size controllable and reducing the memory consumption of the user's graphical interface.
