Detailed Embodiments

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0019] In the description of the embodiments of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0020] In the embodiments of the present invention, the descriptions such as "first", "second", etc. involved are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Therefore, the technical features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0021] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a method, device, and storage medium for automatically generating a schematic circuit diagram sketch, which will be described separately below.

[0023] Figure 1 It is a schematic flowchart of an embodiment of the method for automatically generating a schematic circuit diagram sketch provided by the present invention, as Figure 1 shown, the method for automatically generating a schematic circuit diagram sketch includes: S101. Extract target parameters of the netlist information by using the script function of the circuit drawing software and the file type of the netlist information of the circuit board.

[0024] It should be noted that the execution subject of the method for automatically generating a schematic circuit diagram sketch provided by the present invention may be an electronic device, and a circuit drawing software is installed on the electronic device.

[0025] First, it is necessary to obtain the netlist information of the circuit board. The netlist information is a data file describing the connection relationship between components on the circuit board. The netlist information can be obtained by scanning, testing the circuit board, or extracting from relevant design files, for example, it can be obtained through a tester.

[0026] The file types of netlist information are netlist files or instruction files, and the structures of netlist files and instruction files are different. Select a suitable circuit drawing software, such as Protel, Altium Designer, or EasyEDA, etc. These circuit drawing softwares usually provide a scripting function that allows users to achieve automated operations by writing scripts. By invoking the scripting function of the circuit drawing software, parse the corresponding file type and extract the target parameters of the netlist information.

[0027] In some embodiments of the present invention, the target parameters include: network labels, annotation texts, and position information.

[0028] The network label is a visual symbol for a set of nodes with the same electrical characteristics in a circuit (such as VCC, GND, SPI_CLK), which can replace physical connections in a schematic diagram to simplify the representation of complex circuits.

[0029] The annotation text is the text information associated with component pins, test points, or functional areas. According to the pin information in the netlist file, the annotation text can be generated at the corresponding coordinates.

[0030] The position information is the coordinate information of component pins.

[0031] S102. Based on the target parameters, generate a circuit schematic diagram sketch containing network labels and annotation texts in the circuit drawing software.

[0032] Input the extracted target parameters into the circuit drawing software. The circuit drawing software can automatically generate a circuit schematic diagram sketch containing network labels and annotation texts in the drawing area according to these parameters. The network labels are used to identify each network connection point in the circuit, and the annotation texts can provide explanations about component functions, parameters, etc.

[0033] In summary, the method for automatically generating a circuit schematic diagram sketch provided by the embodiments of the present invention utilizes the scripting function of the circuit drawing software to accurately extract the target parameters according to the file types of the netlist information of the circuit board, avoiding errors that may be introduced by manual operations. Generate a circuit schematic diagram sketch containing network labels and annotation texts in the circuit drawing software according to the target parameters, which can quickly generate an easy-to-read schematic diagram sketch, saving a great deal of time and labor costs compared with traditional manual drawing.

[0034] In some embodiments of the present invention, the file types of the netlist information include: Netlist files or instruction files; The netlist file contains network labels and position information; The instruction file contains instruction information for placing annotation texts and instruction information for placing network labels.

[0035] Exemplarily, there are two types of circuit board netlist files output by the tester, namely the netlist file and the instruction file.

[0036] The netlist file is a structured text file that contains network labels, annotation texts, and coordinates. The netlist file is a netlist file based on the standard Protel netlist, plus location information, and its structure is as follows: / / Network label 1, you can write any comment here { NetR1_1 R1-1,300,1500 R2-1,1000,1500 } / / Network label 2 { GND R1-2,300,1100 R2-2,1000,1100 } As described above, NetR1_1 represents the network label; R1-1 is the annotation text used to represent the pin; (300,1500) is the location information representing the coordinates of the pin.

[0037] The instruction file is a text file containing operation instructions. Among them, PutText represents placing annotation text, and PutNet represents placing network labels, and its structure is as follows: / / The first node PutText R1-1,300,1500 PutNet NetR1_1, 300,1600 / / The second node PutText R2-1, 1000,1500 PutNet NetR1_1, 1000,1600 / / The third node PutText R1-2,300,1100 PutNet GND, 300,1200 / / Comment information test, you can write any comment here PutText R2-2, 1000,1100 PutNet GND, 1000,1200 The instruction file and the netlist file are ordinary text files, and you can also customize special suffix names.

[0038] In some embodiments of the present invention, such as Figure 2As shown, step S102 includes: S202. When the file type is a netlist file, preprocess the netlist file; S202. Extract the target parameters based on the starting character of the preprocessed netlist file.

[0039] When the file type is a netlist file, preprocess the netlist file. For example, blank lines and comment content can be ignored to obtain a preprocessed netlist file.

[0040] Identify the starting character of the preprocessed netlist file (such as {), first extract the network name, parse the pin name and coordinates line by line, generate annotation text and network labels, and obtain the target parameters.

[0041] Optionally, when the file type is an instruction file, preprocess the instruction file. For example, blank lines and comment content can be ignored to obtain a preprocessed instruction file.

[0042] Obtain the network name, annotation text, and location information according to the preprocessed instruction file.

[0043] In some embodiments of the present invention, before step S101, it further includes: Obtain the netlist information of the circuit board through a tester.

[0044] The netlist information of the circuit board can be obtained by using a tester. There are two types of circuit board netlist files output by the tester, namely netlist files and instruction files.

[0045] In some embodiments of the present invention, after step S102, it further includes: Determine the component pins based on the annotation text in the circuit schematic diagram sketch, and replace the network labels in the circuit schematic diagram sketch with wires; Draw a circuit schematic diagram based on the component pins and the wires.

[0046] The generated circuit schematic diagram includes network labels and annotations. The network labels correspond to the netlist, and the annotations correspond to the component pin names. In the schematic diagram, the two correspond one by one and are close together, which is convenient for the drafter to drag them together when adjusting.

[0047] According to the circuit diagram reading requirements, the drafter places component symbols, drags the network labels and annotations of the nodes, deletes or changes the annotations of each node as appropriate, changes the network labels to wires or adjusts them to the bus form, and it is recommended to adjust them in the order of components to ensure no omission or error.

[0048] In some embodiments of the present invention, the circuit drawing software includes any one of the following: Protel, Altium Designer, or LiChuang EDA.

[0049] In the embodiments of the present invention, the circuit drawing software can be EDA software. The EDA software can be Protel, Altium Designer, or domestic software such as LiChuang EDA.

[0050] The method for automatically generating a circuit schematic sketch provided by the embodiments of the present invention can be based on common circuit schematic EDA software (such as Protel). Subsequently, the schematic can be directly adjusted and optimized in the EDA software, making full use of the powerful functions of the EDA software, with good compatibility and low cost.

[0051] In addition, sketch drawing is an important link in the reverse of circuit schematics. In the embodiments of the present invention, by using the script function in Protel (Altium Designer), the circuit board netlist information output by a certain tester is converted into a circuit schematic sketch containing network labels and annotation texts, which can effectively improve the efficiency of circuit schematic reverse.

[0052] The software usage method is as follows: S1. Install the script.

[0053] S1.1. Open the script project, select the "File" - "Open" menu in AD, a "Open" dialog box will pop up, select the file with the suffix PrjScr. For example, if the project is N2S, the project file name is N2S.PrjScr.

[0054] S1.2. Right-click on the toolbar, and select "Customize..." in the pop-up menu to customize the toolbar. It is recommended to close all other files before customization for easier subsequent file selection.

[0055] S1.3. A "Customizing DefaultEditor Editor" dialog box will pop up. In the "Categories" list in the "Commands" area, select "[Scripts]". At this time, select "N2S.PAS" in the "Commands" list and drag it to the toolbar. In the pop-up "Edit Command" dialog box, customize the name and icon. For example, customize the title as "N2S.PAS" and the description as "Netlist to Circuit Diagram Software". At this time, a "N2S" button will appear in the AD software menu bar.

[0056] S1.4. In the "Project" sidebar of the AD software, right-click on the "N2S.PRJSCR" project and select the "CloseProject" command to close the N2S project to avoid automatically loading this project every time AD is opened.

[0057] S2. Use a script.

[0058] S2.1. Click on the "N2S" icon in the AD software menu bar. A netlist to circuit diagram conversion program dialog box will pop up. Select the file type according to the file to be converted, such as "instruction file" or "netlist file", click the "Open" button, and then convert.

[0059] After the conversion is completed, the AD software will pop up a prompt. There is no essential difference between different versions.

[0060] The generated schematic diagram contains net labels and annotations. The net labels correspond to the netlist, and the annotations correspond to the component pin names. In the schematic diagram, the two are in one-to-one correspondence and close together, which is convenient for the drafter to drag them together when making adjustments.

[0061] According to the circuit diagram reading requirements, the drafter places component symbols, drags the net labels and annotations of the nodes, deletes or changes the annotations of each node as appropriate, changes the net labels to connections or adjusts them to the bus form. It is recommended to adjust them in the order of components to ensure no omissions or mistakes.

[0062] There are two types of circuit board netlist files output by a certain tester.

[0063] One is based on the standard Protel netlist, plus location information. The example is as follows: / / Net label 1, write any remarks { NetR1_1 R1-1,300,1500 R2-1,1000,1500 } / / Net label 2 { GND R1-2,300,1100 R2-2,1000,1100 } The other is instruction information. PutText represents placing annotation text, and PutNet represents placing network labels. The example is as follows: / / The 1st node PutText R1-1,300,1500 PutNet NetR1_1, 300,1600 / / The 2nd node PutText R2-1, 1000,1500 PutNet NetR1_1, 1000,1600 / / The 3rd node PutText R1-2, 300, 1100 PutNet GND, 300, 1200 / / Remarks information test, write casually PutText R2-2, 1000, 1100 PutNet GND, 1000, 1200 The instruction file and the netlist file are ordinary text files. Of course, special suffix names can also be customized.
