Based on this, more and more devices are integrated on the printed circuit boards (PCBs) of these products. Checking for fake devices on PCBs is an important step to ensure product quality and supply chain security.

[0003] As we all know, fake devices are usually generated when sub-drawing is used for module reuse.

Therefore, fake devices usually cause PCB short circuits and the formation of isolated copper blocks, which in turn affects the performance of the product. Therefore, in order to ensure product quality, PCB Layout engineers usually manually check, delete or modify fake devices at the end of the design. However, in the prior art, the location of fake devices cannot be directly found through the existing functions of the software, but can only be checked one by one by the PCBLayout engineer.

DETAILED DESCRIPTION

[0021] 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.

[0022] As we all know, fake devices are usually generated when sub-drawing is used for module reuse. For example, devices outside the design appear on the reused module, or devices that are duplicated with the devices already placed in the reused module. In actual applications, fake devices have no network attributes on the PCB board, but they will still be produced normally like other devices. Therefore, fake devices usually cause PCB short circuits and the formation of isolated copper blocks, which in turn affects the performance of the product. Therefore, in order to ensure product quality, PCB Layout engineers usually manually check, delete or modify fake devices at the end of the design. However, in the prior art, the location of fake devices cannot be directly found through the existing functions of the software, but can only be checked one by one by the PCBLayout engineer. Obviously, this is not only inefficient, but also easy to miss.

Therefore, in the present application, since the target PCB board can be quickly checked for fake devices according to the fake device check instruction entered by the user in the Allegro software, compared with the traditional manual one-by-one inspection method, the present application is not only simple to operate and efficient, but also will not be missed.

[0024] After introducing the design ideas of the embodiments of the present application, the following briefly introduces the application scenarios to which the technical solutions of the embodiments of the present application can be applied. It should be noted that the application scenarios introduced below are only used to illustrate the embodiments of the present application and are not limited. In the specific implementation process, the technical solutions provided by the embodiments of the present application can be flexibly applied according to actual needs.

[0025] like Figure 1 As shown, an electronic device provided in an embodiment of the present application is provided, and the electronic device may specifically be a fake device rapid inspection device 10.

[0026] The fake device quick inspection device 10 can be used to quickly inspect fake devices on a PCB board, for example, a personal computer (PC), a server, a laptop, etc. The fake device quick inspection device 10 may include one or more processors 101, a memory 102, an I / O interface 103, and a database 104. Specifically, the processor 101 may be a central processing unit (CPU), or a digital processing unit, etc. The memory 102 may be a volatile memory, such as a random-access memory (RAM); the memory 102 may also be a non-volatile memory, such as a read-only memory, a flash memory, a hard disk drive (HDD), or a solid-state drive (SSD); or the memory 102 is any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory 102 may be a combination of the above memories. The memory 102 may store some program instructions of the method for quickly checking fake devices provided in the embodiment of the present application, and these program instructions can be used to implement the steps of the method for quickly checking fake devices provided in the embodiment of the present application when executed by the processor 101, so as to solve the problem of low efficiency of checking fake devices in the prior art. The database 104 may be used to store data such as the Allegro software, fake device checking program, .il file, and Notepad text editor involved in the solution provided in the embodiment of the present application.

[0027] In the embodiment of the present application, the fake device quick inspection device 10 can obtain the fake device inspection instruction through the I / O interface 103, and then the processor 101 of the fake device quick inspection device 10 will improve the fake device inspection efficiency according to the program instructions of the fake device quick inspection method provided in the embodiment of the present application in the memory 102. In addition, data such as Allegro software, fake device inspection program, .il file and Notepad text editor can also be stored in the database 104.

[0028] Of course, the method provided in the embodiment of the present application is not limited to Figure 1 The application scenarios shown can also be used in other possible application scenarios, and the embodiments of the present application are not limited thereto. Figure 1 The functions that can be realized by each device in the application scenario shown will be described in the subsequent method embodiments, and will not be described in detail here. Below, the method of the embodiment of the present application will be introduced in conjunction with the accompanying drawings.

[0029] like Figure 2 FIG. 1 is a schematic diagram of a method for quickly checking a fake device provided in an embodiment of the present application. The method can be performed by Figure 1 The method is performed by the fake device rapid inspection device 10, and specifically, the process of the method is described as follows.

[0030] Step 201: Start Allegro software.

[0031] In an embodiment of the present application, in order to improve the efficiency of fake device inspection, before starting the Allegro software, it is also necessary to "write a fake device inspection program (set a program call entry shortcut key to facilitate Allegro software calling)" and "use environment settings (program implantation - rewrite the Allegro software interface file to call the skill program)", that is, the skill language can be used to write a fake device inspection program corresponding to the fake device inspection instruction; and the fake device inspection program is implanted into the Allegro software.

[0032] Specifically, when using the skill language to write a fake device inspection program corresponding to the fake device inspection instruction, the skill language can be used to write a fake device inspection program corresponding to the fake device inspection instruction according to the axlCmdRegister() function, axlDBGetDesign() function, axlHighlightObject() function and printf() function, for example, the fake device inspection program is as follows: axlCmdRegister("cds" 'find_dummy_symbols) defun(find_dummy_symbols()) let((allsyms sym) cnt = 0 allsyms = axlDBGetDesign()->symbols foreach(sym allsyms unless(sym->refdes axlHighlightObject(sym) ++cnt ) ) printf("Total dummy symbol: %d\n" cnt) ) ) In addition, when the fake device check program is implanted into the Allegro software, first, the fake device check program can be encapsulated into a .il file; wherein the .il file is an interface file; then, the allegro.ilinit folder pointed to by the computer's environment variable value can be determined. That is, the computer's environment variable value can be checked and the folder pointed to by the variable value can be found; finally, the .il file can be placed in the allegro.ilinit folder, that is, the .il file that implements the fake device quick check function can be placed in the allegro.ilinit folder pointed to by the environment variable value.

[0033] Step 202: receiving a fake device inspection instruction input by a user in a command box of the Allegro software.

[0034] In the embodiment of the present application, the fake device checking instruction is a skill program instruction written by the user.

[0035] After completing the environment settings described in the aforementioned step 201, in the subsequent actual use process, there is no need to re-set the environment. Instead, you only need to enter a call command (fake device check command) to perform a quick check of fake devices (fake devices have no number position, while real devices have number positions). The specific operation is as follows: Enter the fake device check command in the command box of the Allegro software and press the Enter key to confirm, such as Figure 3 , which is a schematic diagram of inputting a fake device check instruction provided in an embodiment of the present application.

[0036] Step 203: Perform a quick fake component check on the target PCB board according to the fake component check instruction.

[0037] In an embodiment of the present application, after entering a fake device check instruction in the command box of the Allegro software and pressing the Enter key to confirm, the .il file can be found directly in the allegro.ilinit folder according to the fake device check instruction; then, the Notepad text editor can be used to open the .il file; finally, the load function can be used to call the .il file, thereby performing a quick check of fake devices on the target PCB board, that is, the load function can be used to call the .il program file according to the allegro.ilinit folder path pointed to by the environment variable, thereby performing a quick check of fake devices on the target PCB board.

[0038] In a possible implementation manner, since the fake device inspection instruction of the present application specifically determines whether each device is a fake device by checking whether each device has a bit number, therefore, in the embodiment of the present application, when the target PCB board is quickly inspected for fake devices according to the fake device inspection instruction, the fake devices on the target PCB board can be highlighted according to the fake device inspection instruction, and the bit numbers of each real device on the target PCB board can be silk-screened, such as Figure 4 As shown, it is a schematic diagram of highlighting fake devices provided in an embodiment of the present application, wherein "C" and "※" on the left are fake devices, so they are highlighted, and "R803" on the right is a real device, so their position numbers are silk-screened.

[0039] In a possible implementation, in order to facilitate users to quickly understand the situation of fake devices, in the embodiment of the present application, after highlighting the fake devices on the target PCB board according to the fake device inspection instruction and silk-screening the bit numbers of each real device on the target PCB board, the number of fake devices can also be displayed in the command box, such as Figure 5 As shown, it is a schematic diagram showing the number of dummy devices provided in an embodiment of the present application.

[0040] To summarize, in the embodiments of the present application, since the fake device check program is written in advance and the fake device check program is set in the Allegro software environment, compared with the traditional manual testing method, the present application only needs to input the execution command (i.e., the fake device check instruction), and the Allegro software can automatically highlight all fake devices. Obviously, the present application is not only simple to operate and efficient, but also will not be missed.

[0041] Based on the same inventive concept, the embodiment of the present application provides a fast detection device 60 for fake devices, such as Figure 6 As shown, the fake device rapid inspection device 60 comprises: A software startup unit 601 is used to start the Allegro software; The instruction receiving unit 602 is used to receive a fake device inspection instruction input by a user in the command box of the Allegro software; wherein the fake device inspection instruction is a skill program instruction written by the user; The fake component inspection unit 603 is used to perform a fake component quick inspection on the target PCB board according to the fake component inspection instruction.

[0042] Optionally, the fake device rapid inspection device 60 further includes a program writing unit 604, which is used to: Using skill language, write a fake device inspection program corresponding to the fake device inspection instruction; The dummy device inspection program is implanted into the Allegro software.

[0043] Optionally, the program writing unit 604 is further used for: A fake device inspection program corresponding to the fake device inspection instruction is written by using Skill language according to axlCmdRegister() function, axlDBGetDesign() function, axlHighlightObject() function and printf() function.

[0044] Optionally, the program writing unit 604 is further used for: Encapsulating the fake device inspection program into a .il file; wherein the .il file is an interface file; Determine the allegro.ilinit folder pointed to by the computer's environment variable value; Place the .il file into the allegro.ilinit folder.

[0045] Optionally, the fake device checking unit 603 is further configured to: According to the fake device check instruction, find the .il file in the allegro.ilinit folder; Use Notepad text editor to open the .il file; The load function is used to call the .il file to quickly check the target PCB board for fake components.

[0046] Optionally, the fake device checking unit 603 is further configured to: According to the fake component inspection instruction, the fake components on the target PCB board are highlighted, and the bit numbers of the real components on the target PCB board are silk-screened.

[0047] Optionally, the fake device checking unit 603 is further configured to: The number of the dummy components is displayed in a command box.
