[0019] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. In addition, although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.

[0020] PCB board, also known as printed circuit board, printed circuit board, or circuit board for short, is made of insulating board as base material, cut into a certain size, with at least one conductive pattern attached to it, and arranged with holes (such as component holes, fastening holes, metallized holes, etc.), which is used to replace the chassis of the previous electronic components and realize the interconnection between electronic components. Because this board is made by electronic printing, it is called a "printed" circuit board.

[0021] The role of device designation on PCB circuit boards is multifaceted. It not only provides key information and guidance, but also helps improve production efficiency, product quality and user experience. Therefore, device designation is an indispensable part of the PCB design and manufacturing process.

[0022] As PCB boards develop towards high precision, devices are getting smaller and smaller, board designs are also getting smaller and smaller, and the space is getting smaller and smaller, but the functions are increasing. The device bit numbers can no longer be fully displayed on the board. Therefore, in order to facilitate the debuggers to quickly locate, PCB layout engineers usually output a bit number map after the design is completed. The bit number map displays the bit numbers of all devices on the device body. However, due to the large number of devices, engineers can easily delete the bit numbers of some devices by mistake during the design process, resulting in an incomplete output bit number map, which makes it difficult for subsequent debuggers to find the corresponding devices for operation.

[0023] Existing software functions cannot locate devices with deleted bit numbers, and PCB layout engineers can only check them one by one, which is too inefficient and easy to miss. In view of this, the present application embodiment provides a method for checking devices without bit numbers, which can be executed by a computer device. Please refer to Figure 1 , which is a schematic diagram of the computer device structure of the hardware operating environment involved in the embodiment of the present application.

[0024] like Figure 1 As shown, the computer device may include: a processor 101, such as a central processing unit (CPU), a communication bus 102, a user interface 104, a network interface 103, and a memory 105. Among them, the communication bus 102 is used to realize the connection and communication between these components. The user interface 104 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the user interface 104 may include a standard wired interface and a wireless interface. The network interface 103 may include a standard wired interface and a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 105 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 105 may optionally also be a storage device independent of the aforementioned processor 101.

[0025] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0026] like Figure 1 As shown, the memory 105 as a storage medium may include an operating system, a network communication module, a user interface module, and a device for checking whether a device has a bit number.

[0027] exist Figure 1 In the computer device shown, the network interface 103 is mainly used for data communication with the network server; the user interface 104 is mainly used for data interaction with the user; the processor 101 and the memory 105 in the computer device of the present invention can be set in the computer device, and the computer device calls the device for checking whether the device has no bit number stored in the memory 105 through the processor 101, and executes the method for checking whether the device has no bit number provided in the embodiment of the present application.

[0028] It should be noted that Figure 1 The computer device shown is installed with Allegro software, which can execute the method for checking the device without a bit number provided in the embodiment of the present application. Allegro is a powerful, flexible and efficient electronic design software, which is widely used in various fields of PCB and packaging design. It has an interface that is convenient for users to conduct secondary development and a relatively complete development language library. Users can conduct secondary development according to their needs on this basis.

[0029] based on Figure 1 The computer equipment shown below Figure 2 A method for checking whether a device has no bit number is introduced as shown in the figure.

[0030] S201. Start the Allegro software, import the initial schematic diagram of the printed circuit board, and display all the components of the printed circuit board.

[0031] In order to implement the method for checking whether a device has no bit number provided in the embodiment of the present application in the Allegro software, in a possible embodiment, before executing S201, the method may further include the following steps: Encapsulate the skill program written by the user into a .il program file, and put the .il program file into the folder pointed to by the environment variable value; use Notepad to open the allegro.ilinit file in the folder; add instructions to call the .il program file through the load function in the allegro.ilinit file.

[0032] In the specific implementation process, first, the user can write the method for checking the device without a bit number provided in the embodiment of the present application into a skill program, and encapsulate the skill program written by the user into a .il program file. The skill program needs to set a program call entry shortcut key to facilitate the Allegro software call. Secondly, you can check the environment variable value of the computer device, find the folder pointed to by the environment variable value, and put the .il program file into the folder pointed to by the environment variable value.

[0033] Next, find the allegro.ilinit file in the folder pointed to by the environment variable value. The allegro.ilinit file is the interface file. Use Notepad to open the allegro.ilinit file and add instructions to call the .il program file through the load function in the allegro.ilinit file, for example: load " / path / to / allegro / scripts / my_script.il", / path / to / allegro / scripts / my_script.il is the actual storage location of the .il program file. Finally, restart the Allegro software. When the user enters the call instruction of the skill program in the command box, the Allegro software will load all the instructions in the allegro.ilinit file and execute the load function to call the .il program file according to the folder path pointed to by the environment variable.

[0034] In the embodiment of the present application, the method for checking the device without a bit number provided in the embodiment of the present application is written based on the skill program and implanted into the Allegro software. The skill program is called by rewriting the system interface file so that the Allegro software can execute the skill program. Skill language is a high-level programming language based on C language and LISP language built into the Cadence Allegro software, which can make good use of the rich interactive functions of the Cadence Allegro software. Using the Skill language as an auxiliary tool for writing can greatly improve work efficiency.

[0035] Furthermore, there are two specific implementations of S201, which are introduced below respectively.

[0036] In the first way, Allegro software is started to display all components of the printed circuit board in response to the user's import operation of the initial schematic diagram of the printed circuit board.

[0037] In the specific implementation process, after starting the Allegro software, the user can manually import the initial schematic diagram of the existing printed circuit board into the Allegro software. After the Allegro software is loaded, all the devices on the printed circuit board will be displayed. These devices usually include resistors, capacitors, integrated circuits, etc., as well as the connections between them.

[0038] The second method is to start the Allegro software, and in response to the user's design operation on the printed circuit board, obtain the initial schematic diagram of the printed circuit board and display all the components of the printed circuit board.

[0039] In the specific implementation process, after starting the Allegro software, the user can enter the design work interface of the printed circuit board and start the design process. After the user completes the initial schematic diagram of the printed circuit board, the Allegro software will display all the devices on the printed circuit board.

[0040] In the embodiments of the present application, It should be noted that the initial schematic diagram of the printed circuit board refers to the PCB schematic diagram that has just been designed and has not yet been checked whether the device has a bit number. The PCB schematic diagram is a schematic diagram of the circuit, showing the electrical connection, component symbols and current flow path. The user can set the user view visibility, and the Allegro software can display the PIN, bit number silk screen, frame, etc. of all devices on the printed circuit board according to the user's settings.

[0041] S202 : In response to a skill program calling instruction input by a user, check whether each device in all devices has a bit number attribute.

[0042] The bit number is used to uniquely identify each device in the PCB. It is usually composed of letters and numbers. The letter part indicates the type of component, and the number part indicates the serial number of the component of that type. For example, R1 and R2 represent two resistors, the first resistor is R1, and the second is R2. Bit number attributes are additional information related to the bit number. These attributes can help describe other characteristics of the device. For example, bit number R1 indicates the first resistor. Bit number attributes may include: 10kΩ resistance value, 0.25W power value, etc.

[0043] In a possible embodiment, in response to a skill program calling instruction input by a user, the bit number attribute data is read from the Ref DesSilkscreen layer; and it is checked whether the bit number attribute of each device in all the devices exists in the bit number attribute data.

[0044] In the actual implementation process, engineers may introduce fake components that do not have properties such as network and position number, such as screw holes and heat sinks, during the design process of the PCB board. Therefore, all components of the PCB board displayed by the Allegro software may include fake components.

[0045] After importing the initial schematic diagram of the printed circuit board, Allegro software automatically generates bit number attribute data in the Ref Des Silkscreen layer (i.e., the silk screen layer), that is, the bit number attributes of the real devices in all devices. For all devices on the PCB board, check one by one whether the bit number attribute of each device exists in the bit number attribute data. If it exists, it means that the device is a real device with bit number attributes. If not, it means that the device is a fake device without bit number attributes.

[0046] In the embodiment of the present application, since fake components will not be involved in testing and repair, it does not matter if they do not have a position number. Therefore, by checking the position number attribute, fake components that do not need to display position numbers can be quickly excluded to avoid subsequent highlighting of fake components.

[0047] S203: If it is determined that any device has a bit number attribute, check whether the bit number of the device is displayed.

[0048] In the specific implementation process, if it is determined that any device does not have the bit number attribute, then the device is skipped and the next device is checked to see if it has the bit number attribute. If it is determined that any device has the bit number attribute, then the bit number of the device is further checked to see if it is displayed.

[0049] S204: If it is determined that the bit number of the device is not displayed, highlight the device.

[0050] In the specific implementation process, if it is determined that the bit number of any device has been displayed, then skip the device and continue to check whether the bit number of the next device is displayed. If it is determined that the bit number of any device is not displayed, it means that the bit number of the device may have been accidentally deleted by the engineer. Therefore, after determining that the bit number of any device is not displayed, the device is highlighted according to the default color or the color set by the user (such as red, yellow, etc.) to highlight the difference of the device. After the user sees the devices of different colors, he can quickly find the devices without bit numbers, and then manually add the bit numbers of these devices in the initial schematic to obtain a complete bit number diagram.

[0051] In a possible embodiment, after executing S204, the method may further include the following steps: Until all devices are checked, the bit numbers and coordinates of multiple highlighted devices are obtained; according to the coordinates of each highlighted device, the bit number of each highlighted device is added to obtain a complete bit number map of the printed circuit board.

[0052] In the specific implementation process, Allegro software will check whether each device on the PCB has a bit number and whether it is displayed, until all devices on the PCB are checked, multiple devices without bit numbers are found, and bit numbers are added to them again to obtain a complete bit number map. The complete bit number map includes the bit numbers of all real devices (other devices except fake devices).

[0053] In an embodiment of the present application, automatically adding bit numbers to highlighted devices can avoid users from manually adding bit numbers of devices one by one, thereby improving the efficiency of adding bit numbers. Subsequent debugging personnel can test, rework, and perform other operations on the PCB board based on the complete bit number map, which can improve the efficiency and accuracy of the operation.

[0054] In a possible embodiment, after all devices are checked and the bit numbers and coordinates of the multiple highlighted devices are obtained, the method may further include the following step: recording the bit numbers and coordinates of the multiple highlighted devices into a target file.

[0055] In the specific implementation process, a target file (no_refdes.log file) is automatically generated in the folder where the schematic diagram is located, and the bit numbers and coordinates of multiple highlighted components are recorded in the target file. Subsequent engineers can manually add bit numbers for each highlighted component based on the target file to ensure the integrity of the final output bit number diagram.

[0056] In a possible embodiment, after recording the bit numbers and coordinates of the plurality of highlight display components into the target file, the method may further include the following steps: Count the number of multiple highlighted devices and record the number of highlighted devices in a target file.

[0057] Please refer to Figure 3 , which is a schematic diagram of the content of the target file provided in the embodiment of the present application. Among them, "Thecomponent without refdes" means "device without a bit number", "Ref_Des" means "bit number", and "Location" means "location coordinate". "Total component without refdes: 7" means "the total number of devices without a bit number is 7". The first device without a bit number: the bit number is RY76, the coordinates are (2338.94, 2925.34), the second device without a bit number: the bit number is CY3, the coordinates are (2303.94, 2925.34), the third device without a bit number: the bit number is RY59, the coordinates are (1918.36, 2733.86), the fourth device without a bit number: the bit number is RY60, the coordinates are (1918.36,2958.86), the fifth device without a bit number: the bit number is R33, the coordinates are (580.0, 570.0), the sixth device without a bit number: the bit number is HOLE3, the coordinates are (1429.13, 1566.93), the seventh device without a bit number: the bit number is U10, the coordinates are (780.0, 1370.0).

[0058] In summary, the embodiment of the present application provides a method for quickly checking devices without bit numbers. After setting up the environment, the user only needs to enter a call command, and the Allegro software will automatically highlight all devices without bit numbers and automatically add bit numbers to the highlighted devices, thereby improving the inspection efficiency and adding efficiency.

[0059] The following example introduces part of the code of the method for checking whether a device has a bit number provided in an embodiment of the present application.

[0060] First, you can use the axlVisibleLayer function to set the display interface, where axlVisibleLayer("PIN / TOP" t ) means displaying all PINs of the TOP layer, and the rest are similar. The specific code is as follows:

[0061] Then, you can use the foreach function to traverse all the devices on the PCB, and then use the if function's judgment condition txt== nil&&symbol->refdes != nil to find the device without a bit number and highlight it. The specific code is as follows:

[0062] Finally, the total number of devices without bit numbers can be output in the command bar through the axlMsgPut function. The specific code is as follows:

[0063] Based on the same inventive concept, Figure 4 As shown, the embodiment of the present application also provides a device for checking whether a device has a bit number, including: The startup module is used to start the Allegro software, import the initial schematic diagram of the printed circuit board, and display all the components of the printed circuit board; A checking module, for checking whether each device among all devices has a bit number attribute in response to a calling instruction of a skill program input by a user; if it is determined that any device has a bit number attribute, checking whether the bit number of the device is displayed; The highlight display module is used to highlight the device if it is determined that the bit number of the device is not displayed.

[0064] It should be noted that the modules in the device for checking whether a device has a bit number in this embodiment correspond one-to-one to the steps in the method for checking whether a device has a bit number in the aforementioned embodiment. Therefore, the specific implementation of this embodiment can refer to the implementation of the aforementioned method for checking whether a device has a bit number, which will not be repeated here.

[0069] As an example, executable instructions may, but need not, correspond to a file in a file system, may be stored as part of a file storing other programs or data, such as in one or more scripts in a HyperText Markup Language (HTML) document, in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files storing one or more modules, subroutines, or code portions).

[0070] By way of example, executable instructions may be deployed to be executed on one computing device, or on multiple computing devices located at one site, or on multiple computing devices distributed across multiple sites and interconnected by a communication network.
