Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0021] Method Implementation Examples Please refer to Figure 1 This invention provides a method for displaying a geometric model, comprising: Step 100: Obtain geometric models of TCAD device simulation post-processing in different file formats; each geometric model includes at least multiple node coordinates and topology information; the topology information represents the connection relationship between the node coordinates.

[0022] Please refer to Figure 2The electronic device first prepares a TCAD device simulation post-processing model, obtaining geometric models of the TCAD device simulation post-processing in different file formats. These geometric models include at least two of the following file formats: bnd model files, tdr model files, and tif model files. Specifically, the geometric models in different file formats may include bnd model files and tdr model files; or they may include bnd model files and tif model files; or they may include tdr model files and tif model files. In one embodiment, to minimize the parsing and display time of electrical simulation post-processing models for a wider variety of TCAD devices, the geometric models in different file formats include bnd model files, tdr model files, and tif model files.

[0023] The geometric model in this embodiment of the invention should meet the requirements of the file content of the post-processed geometric model generated by the TCAD process numerical simulation module. For example, the information in the geometric model file should at least include the node coordinates in space and the topological information of individual regions in space composed of the node coordinates. The topological information is the connection relationship between the node coordinates. In other embodiments, the geometric model may also include element information, as well as the names and values ​​of the electrical physical quantities of the nodes or regions. Please refer to... Figure 3 The element information refers to the coordinates (e.g., vertex coordinates) and dimensions (e.g., side length, volume) of the element's geometric shape (e.g., triangle, quadrilateral, tetrahedron). The electrical physical quantities of nodes or regions can be electric potential, electric field strength, carrier concentration, etc. This process aims to ensure that all necessary data has been properly generated and stored for smooth subsequent processing and display steps. If key information is missing from the file, data needs to be regenerated or supplemented to ensure the required information is complete and accurate. This verification process is fundamental to the entire method implementation, as missing key data can lead to errors or invalid results in subsequent steps. In other words, by verifying the file content, it is ensured that all key data of the geometric model is generated and stored completely and accurately; this process is fundamental to subsequent processing and display, as missing key data can lead to errors or invalid results in subsequent steps. In one embodiment, the geometric model includes the following file content: {node coordinates, topological information, physical quantity information}.

[0024] This invention can use computer scripts such as Python to read geometric models of TCAD devices after simulation processing in different file formats. In one embodiment, the pseudocode for an electronic device to acquire geometric models of TCAD devices after simulation processing in different file formats is as follows: # Read multiple model files file_paths = ["path / to / file1", "path / to / file2", "path / to / file3"] abstract_layers = process_multiple_model_files(file_paths) # Read geometric model file model_file = read_model_file("path / to / file") if validate_model_file(model_file): node_coords = model_file.node_coordinates topo_info = model_file.topology_info else: raise ValueError("Invalid model file") Please refer to Figure 4 and Figure 5 , Figure 4 To read the schematic diagram of the bnd model, Figure 5 This is a diagram illustrating the reading of a TDR file. It should be noted that... Figure 5 The colors, from blue to red, represent electric field strength from low to high.

[0025] Furthermore, the electronic device in this embodiment of the invention can use a corresponding custom reader to parse the file contents of BND model files, TDR model files, and TIF model files, and store the parsing results in memory. The specific implementation is as follows: def __init__(self, file_name=None): self.file_name = file_name if self.file_name is not None: if file_name.endswith('.bnd'): self.__read_from_bnd() elif file_name.endswith('.tdr'): self.__read_from_tdr() elif file_name.endswith('.tif'): self.__read_from_tif() else: raise ValueError(f"Unsupported file type: {file_name}") Step 200: Map the geometric models of different file formats to the abstraction layer interface based on a unified set data structure.

[0026] This invention designs a unified abstraction layer interface (hereinafter referred to as the abstraction layer interface). This step aims to provide a unified interface standard, enabling model files of different formats to be processed and displayed through the same interface. In other words, the purpose of designing a unified abstraction layer interface is to provide a unified interface for subsequent processing and display steps, allowing different types of model files to be processed and displayed through the same interface. By defining the abstraction layer interface, the content of model files of different formats can be mapped to a unified interface, thereby simplifying the processing of different format files and reducing the workload of development and maintenance. Simultaneously, by defining a unified interface, it is easier to extend and optimize different types of model files, improving the system's flexibility and scalability; the pseudocode is as follows: # Define abstract layer interface interface AbstractDisplayLayer { List <node>nodeCoordinates; List <element>elements Map<Node, PhysicalQuantity> nodePhysicalQuantities. Map<Region, PhysicalQuantity> regional Physical Quantities } The electronic device maps geometric model files from TCAD simulation post-processing in different file formats to an abstraction layer interface. The mapping process mainly involves reading the post-processing geometric model files and reorganizing the read geometric model information according to the abstraction layer interface specifications. By integrating the information from model files of different file formats into a single abstraction layer interface, the system automatically identifies and reads different types of model files, then maps their contents to a unified abstraction layer interface, thereby simplifying the processing and improving the system's flexibility and efficiency. This process avoids developing separate processing programs for each file format, reducing development and maintenance workload. In other words, the content of various model files in different formats can be uniformly converted into the data structure of the abstraction layer interface, achieving unified processing of different file formats. Through a unified abstraction layer interface, the content of different types of model files is abstracted into the same structure, allowing subsequent display and processing steps to operate in a consistent manner, thus simplifying the processing and improving the system's efficiency and reliability. Furthermore, by mapping and integrating the read information from different types of post-processing models into a single abstraction layer interface, subsequent work only needs to focus on maintaining the model processing interface of this abstraction layer interface. By maintaining and optimizing this interface, the visualization display requirements of post-processed models of different types (i.e., different formats) can be handled efficiently. There is no need to perform tedious and complex operations for each specific model type, which greatly improves work efficiency and reduces maintenance costs.

[0027] In one embodiment, step 200, mapping the geometric models of different file formats to an abstraction layer interface based on a unified set data structure, includes: converting each geometric model into a set data structure of mesh data-attribute data-visual objects-visual parameters; and sending the set data structure corresponding to each geometric model after conversion to the abstraction layer interface. The mesh data includes a region ID and the corresponding mesh. The visual objects include fonts, outlines, titles, coordinate axes, etc. The visualization parameters include display edge lines, opacity, color mapping scheme, display scalar color bars, color value range limits, logarithmic scale, etc. The attribute data includes region name, vector name, scalar name, maximum and minimum scalar values, contour lines, etc.

[0028] The data structure of the unified abstraction layer interface set in this embodiment of the invention is implemented through the following pseudocode: class AbstractMesh: def __init__(self, file_name=None): # Define grid data self.meshes = {} # This is the region ID and the corresponding mesh. self.mesh = None # This is the entire mesh put together. # Define Visual Objects self.actors = {'glyph': None, 'contour': None, 'grid': None, 'title':None, 'axes': None} self.mesh_actors = {} # This is the actor for the mesh divided into regions. self.plotter = None # This is the plotter for drawing. # Define visualization parameters self.dargs = {'show_edges': True, 'opacity': 1, 'cmap': 'jet', 'show_scalar_bar': True, 'clim': None, 'log_scale': False, 'scalars': None} # Define attribute data self.materials_name = defaultdict(lambda: []) # This is a mapping of material names to their corresponding regions. self.regions_name = {} # This is a mapping between region names and their corresponding region IDs. self.vectors_name = set() # This is the name of the vectors self.scalars_name = set() # This is the name of the scalar. self.scalars_max = {} # This is the maximum value of the scalar. self.scalars_min = {} # This is the minimum value of the scalar. self.datasets_units = {} # This is the unit of the dataset. self.glyphs = {} # This is a vector glyph self.contours = {} # This is the contour line Step 100 uses `read_from_bnd`, `read_from_tdr`, and `read_from_tif` to read and parse files of different formats. These methods parse the file content into a unified abstraction layer internal data structure, such as meshes and meshes, for subsequent display and processing. This embodiment of the invention uses a .tdr file as an example, and the specific implementation is as follows: def __read_from_tdr(self): tdr_reader = tdrReader(self.file_name) tdr_reader.parse() # Populate the unified abstraction layer data structure.

[0029] In this embodiment of the invention, each geometric model is converted into a defined data structure consisting of mesh data, attribute data, visualization objects, and visualization parameters; and the converted defined data structure corresponding to each geometric model is sent to the abstraction layer interface. This enables the mapping function. Model file → Abstract layer interface.

[0030] This invention achieves efficient display and management of geometric model files of various post-processing types through a unified data structure and processing flow.

[0031] Step 300: Display the geometric models of different file formats of the abstract layer interface based on the set display tool.

[0032] Electronic devices can use open-source post-processing display modules such as PyVista or self-developed TCAD simulation post-processing software to display the abstract layer model. In one embodiment, the pseudocode representation of displaying geometric models of different file formats of the abstract layer interface based on a set display tool is as follows: # Display Model def display_model(abstract_layer): software = TCADPostProcessingSoftware() # Load abstraction layer data software.load_abstract_layer(abstract_layer) # Set display parameters display_params = DisplayParameters() display_params.show_nodes = True display_params.show_elements = True display_params.show_physical_quantities = True # Display Model software.display(display_params) Please refer to Figures 6 to 8 , Figure 6 , 7 8 is a post-processing model file for all file formats that is displayed in separate regions through an abstract layer interface. Figure 9 This invention provides a TCAD model visualization contour map using an abstract layer interface mapping. Figure 10 This invention provides a TCAD model visualization vector diagram using an abstract layer interface mapping. It should be noted that... Figures 6 to 10 The colors, from blue to red, represent electric field strength from low to high.

[0033] This invention, through an abstraction layer interface, maps geometric models of different file formats to a unified data structure, enabling the display of these models using a designated display tool. This improves the processing efficiency of displaying geometric models from various types of TCAD device simulation post-processing, and reduces the development and maintenance costs associated with this process. Furthermore, this invention can efficiently handle the display requirements of different types of TCAD device electrical simulation post-processing models, significantly improving processing efficiency, simplifying the process, and ensuring the accuracy and reliability of the display results.

[0034] In other aspects of the embodiments of the present invention, after displaying the geometric models of different file formats of the abstract layer interface based on the setting display tool, the method further includes: in response to the setting instruction of the display requirement, determining a first display requirement for the first geometric model; and using the setting display tool to display the first geometric model based on the first display requirement.

[0035] In addition to using open-source post-processing display modules such as PyVista or self-developed TCAD simulation post-processing software to display post-processed geometric models of different file formats of the abstraction layer interface, the electronic device can also use self-developed post-processing software to perform interactive operations on the model. For example, the electronic device receives a user-input display requirement setting command. Responding to the display requirement setting command, the electronic device determines a first display requirement for the first geometric model; and uses the setting display tool to display the first geometric model based on the first display requirement. The first geometric model can be any one of different file formats, namely, any one of a BND model file, a TDR model file, or a TIF model file. The first display requirement includes at least one of display nodes, regions, and physical quantities. For example, the user's display requirement is to verify the effect of node voltage (gate voltage Vg) on ​​channel potential. Responding to the above display requirement, the electronic device extracts the node potential data of the channel region below the gate and plots the Vg-channel potential curve. Then, using self-developed post-processing software, it marks the channel center node (e.g., coordinates (x, y)) and plots the potential variation curve with Vg.

[0036] Therefore, this embodiment of the invention supports the selection and display of different nodes, regions, and physical quantities. This step enables the display of model files in different file formats in a unified manner, and allows for the selection and display of different nodes, regions, and physical quantities as needed. The purpose of this process is to provide a unified display platform, allowing users to easily view and analyze different types of model data, improving work efficiency and the accuracy of data processing.

[0037] In other aspects of the embodiments of the present invention, the method further includes: optimizing the set data structure corresponding to each geometric model in the abstraction layer interface based on a redundant data removal function or a computational efficiency optimization function.

[0038] By maintaining and optimizing the abstraction layer interface, the system can efficiently handle the display requirements of geometric models in different file formats. Through this process, the design and implementation of the abstraction layer interface can be continuously optimized and improved, ensuring that the system can efficiently process and display different types of model data, thereby improving the overall performance and reliability of the system. The optimization process may include optimizing the defined data structure corresponding to each geometric model in the abstraction layer interface based on optimization functions (such as redundant data removal functions or computational efficiency optimization functions). The pseudocode for optimizing the abstraction layer interface based on optimization functions is as follows: # Maintain and optimize the abstraction layer interface def optimize_display_layer(abstract_layer): # Optimize operations, such as removing redundant data and improving computational efficiency. optimized_layer = perform_optimizations(abstract_layer) return optimized_layer The redundant data removal function dynamically adjusts the mesh density, reducing redundant nodes in non-critical areas and refining the mesh in physically sensitive areas. The pseudocode for optimizing the abstraction layer interface using the redundant data removal function is as follows: def adaptive_mesh_refinement(abstract_layer,critical_regions=["gate_oxide","pn_junction"], base_ratio=0.3, refine_factor=5): # Non-uniform mesh optimization: refine the mesh in critical regions and simplify the mesh in non-critical regions. :param critical_regions: List of physically sensitive regions that need to be encrypted :param base_ratio: Base simplification ratio (0.3 means reducing non-critical area mesh by 70%) :param refine_factor: Key area mesh refinement factor.

[0039] The pseudocode for optimizing the abstraction layer interface by calculating the efficiency optimization function is as follows: def quantize_field_data(abstract_layer, fields=["DopingConcentration", "ElectricField"], bits=12, sparse_threshold=1e-3): #Scalar Field Data Quantization and Sparse Storage :param bits: Quantization bit width (12-bit balanced precision and storage) :param sparse_threshold: Sparsification threshold (a change rate < 0.1% is considered constant) Memory savings are achieved through computational efficiency optimization functions, 12-bit quantization reduces storage by 50%, and sparse storage is further reduced to 20% of the original data.

[0040] This invention, through the maintenance and optimization of this abstraction layer interface, can efficiently handle the visualization display requirements of different types of post-processing models, eliminating the need for tedious and complex operations for each specific model type. This significantly improves work efficiency and reduces maintenance costs. The main purpose of optimizing the abstraction layer interface is to improve the system's processing efficiency and display effects, ensuring that the system can efficiently process and display different types of model data. In this process, the system will continuously optimize and improve the design and implementation of the abstraction layer interface, thereby improving the overall performance and reliability of the system.

[0041] Therefore, this embodiment of the invention reads and maps various types of TCAD device post-processing models to a unified abstraction layer interface, displaying TCAD device electrical simulation post-processing files of different standards using the same abstraction layer interface. This method can shorten the parsing and display time of various types of TCAD device electrical simulation post-processing models, reduce development costs, and improve program maintainability. Furthermore, the above steps can efficiently handle the display requirements of different types of TCAD device electrical simulation post-processing models, significantly improving processing efficiency, simplifying the processing procedure, and ensuring the accuracy and reliability of the display results.

[0042] This invention can read and parse various types of post-processing geometric model files and map them to a unified abstraction layer interface, saving time and resources compared to processing different file formats individually. This unified abstraction layer interface supports various display requirements, including displaying different nodes, regions, and physical quantities, making the display process more efficient and intuitive. Through the implementation of this abstraction layer interface, system maintenance and optimization work is concentrated at this layer, greatly simplifying the overall system maintenance and upgrade process.

[0043] In other words, the geometric model display method of this invention has the following advantages: Traditional methods parse and display each file format separately. This invention, through a unified abstraction layer interface, only requires one abstraction layer interface mapping, decomposing the parsing and display of different file formats into a unified display layer process. This eliminates the need for separate development and maintenance for each file format, reducing processing time and resource consumption.

[0044] Second, by designing an abstract layer interface, information from different types of geometric model files is mapped to a unified interface standard, reducing the complexity of model parsing and display.

[0045] Third, to solve the problem of low efficiency in reading and displaying multiple types of models, we constructed a unified interface based on the abstract layer interface. Since this invention avoids developing separate processing programs for each type of file, the abstract layer interface is equivalent to a unified processing interface, which ultimately meets the display requirements of efficient processing of post-processing models of multiple types of TCAD devices, and verifies the processing efficiency and display effect.
