[0050] See also Figure 1 , Figure 1 The present invention is a flowchart of a method for automatically generating schematic symbols provided by an embodiment of the present invention.

[0051] A method for automatically generating schematic symbols according to an embodiment of the present invention comprises the following steps:

[0052] S100, identifying the product manual of the component to be identified based on the document automatic recognition technology, and obtaining the pin information of the component; wherein the pin information includes the pin name and pin number of the component.

[0053] In this embodiment, the pin information of the component indicates the number, position and function of the pins of the component. Pins are usually drawn with lines and marked with corresponding pin numbers and names. Based on the document automatic recognition technology, the product manual of the component to be identified is identified to obtain the pin information of the component. The entire process is completed by automatic processing, which greatly improves efficiency, saves labor costs, and effectively avoids errors that are prone to occur when manually obtaining information.

[0054] In a specific embodiment, the step S100 identifies the product manual of the component to be identified based on the document automatic recognition technology, and obtains the pin information of the component, including the following steps:

[0055] S110, automatically identifying and intercepting schematic diagram symbols in the product manual of the component based on the document automatic recognition technology;

[0056] S120, extracting the pin information of the component from the schematic symbol chart.

[0057] In this example, see Figure 2 and Figure 3 , read the product manual, automatically identify and extract the schematic symbol chart of the components recommended in the manual, and identify and extract the pin information in the schematic symbol chart, such as the pin name and pin number, for the generation of the schematic symbol model file.

[0058] Specifically, component product manuals in common formats (such as PDF, WORD, etc.) are scanned. When a page containing component symbol diagrams is scanned in the product manual, the image recognition technology in the document automatic recognition technology is used to locate and capture the recommended component symbol diagrams. Then, the OCR (optical character recognition) technology in the document automatic recognition technology is used to identify regular font characters and special symbols, subscripts, superscripts and other marking forms in the field of electronic components to ensure accurate extraction of pin names and pin numbers in the schematic symbol diagrams.

[0059] S200, reading the packaging file of the component through application software, and automatically identifying the pad information of the component; wherein the pad information includes pad number, pad coordinates and direction information.

[0060] In this embodiment, the application software includes but is not limited to Electronic Design Automation (EDA) software, such as KiCad software, Cadence software, Altium Designer software, etc.

[0061] See also Figure 4 and Figure 5 By reading the package file of the EDA software, the pad information of the package model in the package file, such as pad coordinates and layout information, is obtained, and the schematic symbol model file is generated in a way that keeps the positional relationship consistent. This ensures that the generated schematic symbol has consistency and readability with the package model pad layout, thereby ensuring the correctness of the schematic symbol model.

[0062] In a specific embodiment, before the step S200 of reading the package file of the component by the application software and automatically identifying the pad information of the component, the following steps are also included:

[0063] S400: Retrieve the packaging file of the component through the import interface of the application software.

[0064] In this embodiment, after the user selects the packaging file, the packaging file of the component is retrieved through the import interface of the application software to read the content of the packaging file.

[0065] In a specific embodiment, the step S200 reads the package file of the component by application software to automatically identify the pad information of the component, including the following steps:

[0066] S210, reading the packaging file of the component through the application software, and automatically identifying the packaging type described in the packaging file;

[0067] S220. Automatically extract pad information of each pad in the package file according to the package type.

[0068] In this embodiment, the package file of the component is read to identify the package type described in the package file, and common package types such as SMD (Surface Mounted Devices), DIP (Dual In-line Package), and BGA (Ball Grid Array) can be identified. Then, the underlying data structure of the package file is parsed to extract the information of each pad, such as Figure 5 As shown, it includes pad number, coordinate position and pad direction information (such as horizontal, vertical, rotation angle, etc.) The information extraction process of the embodiment of the present invention is automated and data accuracy is guaranteed, so as to prepare for the subsequent construction of the schematic symbol model.

[0069] S300. Generate a schematic symbol model file consistent with the pad information according to the pin information and the pad information of the package file and in accordance with a set rule; wherein the schematic symbol model file includes the schematic symbol of the component.

[0070] In this example, see Figure 6 , based on the read symbol chart pin information and package file pad information, the various parameters required for symbol design are automatically calculated according to pre-set rules, and then a schematic symbol model file consistent with the package pad layout is generated.

[0071] In a specific embodiment, the step S300 generates a schematic symbol model file consistent with the pad information according to the pin information and the pad information of the package file according to a set rule, and includes the following steps:

[0072] S310, automatically determining the type of the component;

[0073] S320, automatically matching a set symbol pattern usage rule according to the type of the component and the package type of the package file;

[0074] S330, generating a schematic diagram symbol model file consistent with the pad information according to the rule of using the symbol pattern, the pin information and the pad information.

[0075] In this process, the pin number and pin name information in the product manual are automatically extracted, the pad coordinates and pad layout information in the package file are automatically extracted, and the schematic symbol model file is generated based on this information and set rules.

[0076] Specifically, based on the pin information of the schematic symbol chart and the pad information of the package file, the classification of components is automatically determined, such as analog devices, digital devices or mixed-signal devices, and the package pad information is combined to determine the package detail parameters, such as pin spacing, package size, etc. Then, based on the determined components and package types, the pre-set symbol pattern usage rules are automatically matched and enabled.

[0077] In a specific embodiment, the symbol pattern usage rule includes a single symbol layout rule, a heterogeneous multi-unit symbol layout rule, or a homogeneous multi-unit symbol layout rule.

[0078] Specifically, for single-symbol devices, the pin layout position is planned according to the principle of simple layout to ensure that the symbol is easy to read; for heterogeneous multi-unit symbols, differentiated and coordinated pin layouts are designed based on the functional associations and electrical connection characteristics of each unit; for homogeneous multi-unit symbols, the symmetrical and regular layout paradigm is followed to improve the standardization of the symbol.

[0079] Finally, by combining the rules for using symbol patterns, pin information, and pad information, a schematic symbol model file readable by EDA software is automatically generated so that it can be successfully applied to circuit design and other related links in the future.

[0080] In a specific embodiment, the step S330 generates a schematic symbol model file consistent with the pad information according to the symbol pattern usage rule, the pin information and the pad information, comprising the following steps:

[0081] S331, calculating the schematic diagram symbol pin parameters of the component according to the pin information and the pad information; wherein the schematic diagram symbol pin parameters include the symbol pin position and the symbol pin direction corresponding to the pad information;

[0082] S332. Generate a schematic symbol model file according to the symbol pattern usage rules and the schematic symbol pin parameters.

[0083] In this example, see Figure 6 , the extracted pin information and pad information are used to calculate the schematic symbol pin layout position, direction and other parameters of the component according to the package pad layout. Specifically, according to the pin information, the number of pins is obtained, and then the same number of pins are set accordingly in the schematic symbol, and then the position and direction of the pins in the schematic symbol are determined according to the actual layout position and direction of the package pad. Finally, the schematic symbol pin parameters are converted into a visual schematic symbol model file.

[0084] During the generation process, the pin line thickness and length are standardized in accordance with the industry's common drawing specifications, and the overall size and proportion of the symbol are adaptively adjusted according to different design scenarios. The generated schematic symbol model file is stored in the specified directory for user convenience and use in subsequent circuit design processes.

[0085] In summary, an embodiment of the present invention provides a method for automatically generating schematic symbols. First, based on the document automatic recognition technology, the product manual of the component to be identified is identified, and the pin information of the component is obtained. The entire process is completed automatically, which greatly improves efficiency and saves labor costs, and effectively avoids errors that are prone to occur when manually obtaining information; then, the package file of the component is read by the application software, and the pad information of the component is automatically identified. The schematic symbol model file is generated in a manner that maintains a consistent positional relationship, which can ensure that the generated symbol has consistency and readability with the package model pad layout, thereby ensuring the correctness of the schematic symbol model; finally, according to the pin information and the pad information of the package file, a schematic symbol model file consistent with the pad information is generated according to the set rules, and some missing symbol pins can be automatically optimized and supplemented with the help of logical calculations to ensure that the symbol pins and the package pads can correspond one to one, further improving the accuracy of the schematic design.
