Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Therefore, the detailed description of the embodiments of the present invention provided in the following figures is not intended to limit the scope of the claimed invention but is merely representative of selected embodiments of the present invention.

[0044] Traditionally, the MVB network card issuance process includes two parts, hardware and software. The existing method is to develop the software and hardware separately. After the hardware and software are developed, the software is verified on the hardware for system correctness. However, during the above operation, if the device is damaged during welding or installation of the hardware part, an error will be generated when the software is verified on the hardware for system correctness, and it will be impossible to identify whether it is a software problem or a hardware problem.

[0045] Based on the above description, the embodiment of the present invention proposes a method as follows Figure 1-3 The MVB network card stability test system shown includes:

[0046] A collection module, the collection module is used to obtain MVB network card parameters;

[0047] A simulation module, wherein the simulation module constructs a virtual MVB network card based on MVB network card parameters;

[0048] A test module, wherein the test module is used to synchronously test the virtual MVB network card and the MVB network card;

[0049] An analysis module is provided, wherein the analysis module performs result analysis based on the test results of the virtual MVB network card and the MVB network card. Specifically, the test results of the virtual MVB network card and the MVB network card are obtained respectively, and binarization processing is performed. When the binarization processing of the same test items in the test results is different, the corresponding test items are marked as feedback items, and feedback is performed on the feedback items. When the binarization processing of the same test items in the test results is the same, the corresponding test items are marked as result items, and the test results are output. By establishing a virtual MVB network card, there will be no hardware damage during the test, and a comparison group is formed with the MVB network card during the test. The stability test results are obtained by analyzing the test results. At the same time, by establishing a virtual MVB network card, extreme tests can also be performed in the simulation software, such as high temperature resistance test, reliability test and life test, etc., to increase the diversity of the stability test of the MVB network card.

[0050] The present application is described in detail below with reference to specific embodiments;

[0051] like Figure 1 As shown, in one embodiment, the acquisition module can be a camera with a shooting function, or it can be acquisition software for acquiring images. The present invention is not specifically limited here. The graphic information of the MVB network card, such as the engineering drawings and engineering pictures of the MVB network card, is obtained through the acquisition module. The graphic information of the MVB network card is recognized through image recognition software, such as Baidu Image Recognition, to obtain the hardware information of the MVB network card, such as the host computer interface, bus transceiver, software interface, controller, communication memory, software installation board and MVB bus. The hardware information also includes the connection relationship between the host computer interface, bus transceiver, software interface, controller, communication memory, software installation board and MVB bus.

[0052] like Figure 3As shown, in one embodiment, after the simulation module obtains the hardware information of the MVB network card, the hardware information is simulated by the modeling software, for example, by SimSoC or QEMU software. In the specific implementation process, the VHDL code can be referred to, and the SystemC language can be used to model the upper computer interface, bus transceiver, software interface, controller, communication memory and MVB bus at the behavioral level. In the process of referring to the VHDL code, the VHDL The information related to the clock cycle contained in the code can be ignored when performing level abstraction; usually, the MVB network card can usually be an ARM board, which includes a processor, an interrupt controller, an internal bus, a memory, and simulations of functional modules such as UART and GPIO. The built-in ARM processor, memory, virtual bus and other modules of SimSoC are reused to respectively realize the simulation of the processor, interrupt controller, memory, internal bus and other modules of the virtual ARM board. More specifically, in this embodiment, a host computer interface unit corresponding to the host computer interface, a bus transceiver unit corresponding to the bus transceiver, a software interface unit corresponding to the software interface, a control unit corresponding to the controller, a storage unit corresponding to the communication memory, a software installation unit corresponding to the software installation board and a virtual MVB corresponding to the MVB bus are established through SimSoC software. Bus; each unit uses built-in signals (Signal), ports (Port) and sockets (Socket) to bind between units; in the specific implementation process, a SystemC process can be used to simulate a virtual MVB bus simulation, and then the software data in the MVB network card is cloned by the host computer, and the software data is written into the virtual MVB network card hardware to complete the construction of the virtual MVB network card; by building a virtual MVB network card, the MVB network card in real life can be copied, and physical testing can be achieved. The virtual MVB network card can be sent to customers for testing, which reduces logistics costs and allows customers to feel the test data more intuitively.

[0053] In one embodiment, the host computer interface unit is used for the virtual MVB network card to exchange commands and / or data with the host computer; the bus transceiver unit is used for the virtual MVB network card to exchange data and / or commands with the virtual MVB bus. The software interface unit is used to implement the interaction of data and / or commands between the software running on the software installation board and the control unit. The storage unit corresponding to the communication memory is used to implement storage tasks such as storage and temporary storage of various data during the communication process. In the specific implementation, QEMU can be used to realize the simulation of the host computer, thereby realizing not only the integration verification between the internal software and hardware of the MVB network card, but also the verification of the interaction between the MVB network card and the host computer. The virtual host computer can load the same software stack as the real host computer (specifically including the operating system and the host computer's application program, etc.). Figure 1-3 The block diagram shown is a test of a virtual MVB network card using a QEMU virtual host computer. The QEMU virtual host instance used for verification is input into the monitoring layer of the QEMU virtual host computer through the PC104 bus. The monitoring layer of the QEMU virtual host computer adds a read and write frame listening function to the port address corresponding to the PC104 bus. When the program running by the QEMU virtual host computer instance generates read and write through the PC104 bus, the corresponding read and write listening function will be triggered, and then in the listening function, the host computer interface unit of the virtual MVB network card is communicated through the IPC method.

[0054] In one embodiment, the test module pre-stores test instructions that are pre-adapted to the MVB network card, such as communication test instructions, stress test instructions, and error frame test instructions. When the host computer is connected to the host computer interface unit in the virtual MVB network card and the host computer interface on the MVB network card respectively, the test module sends test instructions to the virtual MVB network card and the MVB network card at the same time node. Subsequently, within the specified time, the virtual MVB network card and the MVB network card complete the test instructions and generate test results. By pre-installing several test instructions in the test module, the MVB network card can be conveniently tested to increase the degree of integration.

[0055] In one embodiment, after the test results generated by the virtual MVB network card and the MVB network card are obtained by the analysis module and binarized. When the binarization processing of the same test items in the test results is different, the corresponding test items are marked as feedback items, and feedback is given to the feedback items. When the feedback items corresponding to the virtual MVB network card are binarized as unsatisfied and the feedback items corresponding to the MVB network card are binarized as satisfied, the acquisition module will re-acquire the MVB network card parameters and send them to the simulation module to rebuild the virtual MVB network card. When the feedback items corresponding to the virtual MVB network card are binarized as satisfied and the feedback items corresponding to the MVB network card are binarized as unsatisfied, the acquisition module will send the acquired MVB network card parameters to the host computer for display. By comparing the virtual MVB network card and the MVB network card through binarization, the virtual MVB is realized. Bidirectional dynamic comparison between the network card and the MVB network card. For example, in the first case mentioned above, it can be inferred that an error occurred in the modeling of the virtual MVB network card, and there is no need to repair the virtual MVB network card. In the second case, it can be inferred that the hardware part of the MVB network card failed, so after the stability test, there is no need to test the software part, which reduces the time for troubleshooting after the test.

[0056] When the binarization processing of the same test items in the test results is the same, the corresponding test items are marked as result items, and the test results are output.

[0057] It can be concluded from the above embodiments that the present application can achieve rapid positioning of situations occurring during and after stability testing and reduce testing time by setting at least one virtual MVB network card and one MVB network card.

[0058] like Figure 2 As shown, in addition to the above, the present application also provides an MVB network card stability test method, which is applicable to the above-mentioned MVB network card stability test system, including step 1: collecting MVB network card parameters and building a virtual MVB network card;

[0059] Step 2: Synchronously test the virtual MVB network card and the MVB network card, and collect the test results;

[0060] Step 3: Binarize the test results;

[0061] Step 4: When the binarization processing of the same test item in the test results is different, execute step 5; otherwise, execute step 6;

[0062] Step 5: When the feedback item corresponding to the virtual MVB network card is binarized as unsatisfied and the feedback item corresponding to the MVB network card is binarized as satisfied, the acquisition module will re-acquire the MVB network card parameters and send them to the simulation module to rebuild the virtual MVB network card;

[0063] When the feedback item corresponding to the virtual MVB network card is binarized and is satisfied, and the feedback item corresponding to the MVB network card is binarized and is not satisfied, the acquisition module sends the acquired MVB network card parameters to the host computer for display;

[0064] Step 6: Output the test results.

[0065] The technical effect brought about by the MVB network card stability test method is the same as that of the MVB network card stability test, so it will not be repeated here.

[0066] In a further specific implementation, a storage medium is also included, on which executable instructions are stored, and when the executable instructions are executed by a processor, the steps in the MVB network card stability testing method are implemented.
