Technical Field

[0001] This application relates to the field of communication technology, and in particular to a verification circuit and electronic device. Background Technology

[0002] With the rapid development of wireless communication, wireless communication modules are widely used in fields such as power grids and vehicle-to-everything (V2X). However, verifying the functionality of wireless communication modules requires designing corresponding development boards based on the module's packaging type (such as next-generation form factor (NGFF) or land grid array (LGA)) and function (such as the module acting as a controller or transmitting data as a slave device). This results in a wide variety of development board types for verifying module functionality, leading to high R&D costs.

[0003] Therefore, reducing the number of development board types used to verify module functionality is a problem. Utility Model Content

[0006] The first wireless communication module is connected to the first interface of the switching circuit, the second wireless communication module is connected to the second interface of the switching circuit, the controller is connected to the third interface of the switching circuit, and at least one slave device is connected to at least one fourth interface of the switching circuit.

[0007] The first wireless communication module is used to control at least one slave device when the first interface and at least one fourth interface of the switching circuit are set to a connected state; or, the second wireless communication module is used to control at least one slave device when the second interface and at least one fourth interface of the switching circuit are set to a connected state.

[0008] The first wireless communication module is configured to be in a closed state when the first and third interfaces of the switching circuit are set to the open state, acting as a slave module controlled by the controller; or, the second wireless communication module is configured to be in a closed state when the second and third interfaces of the switching circuit are set to the open state, acting as a slave module controlled by the controller.

[0009] As can be seen, the switching circuit enables either the first or second wireless communication module to control at least one slave device, and it also enables either the first or second wireless communication module to act as a slave module controlled by the controller. This facilitates the verification of the functions of the first or second wireless communication module (such as control functions or module functions as a slave module) within the same verification circuit, thereby reducing the number of development boards required for verifying module functions when applying this verification circuit to a development board.

[0010] Optionally, the first interface and at least one fourth interface of the switching circuit are set to the on state, the second interface and at least one fourth interface of the switching circuit are set to the on state, the first interface and the third interface of the switching circuit are set to the on state, and the setting of the second interface and the third interface of the switching circuit to the on state is based on software or hardware control.

[0017] As can be seen, based on the first and second switches, the first or second wireless communication module can control the first slave device, or the first or second wireless communication module can be controlled by the controller as a slave module.

[0020] The fifth interface is the first interface of the switching circuit, the sixth interface is the second interface of the switching circuit, the tenth interface is the third interface of the switching circuit, and the twelfth and thirteenth interfaces are two of at least one of the fourth interfaces of the switching circuit.

[0021] The first wireless communication module is connected to the first switch via the fifth interface, the second wireless communication module is connected to the first switch via the sixth interface, the seventh interface of the first switch is used to connect to the eighth interface of the second switch, the ninth interface of the second switch is used to connect to the eleventh interface of the third switch, the tenth interface of the second switch is used to connect to the controller, the twelfth interface of the third switch is used to connect to the first slave device, and the thirteenth interface of the third switch is used to connect to the second slave device.

[0037] To better understand the verification circuit disclosed in the embodiments of this application, the relevant terms in the embodiments of this application are explained below.

[0038] (1) Wireless communication module A wireless communication module is a functional component that enables terminal devices to connect to networks and transmit information. It is widely used in point-of-sale (POS) terminals, power grid equipment, vehicle networking terminals, customer premises equipment (CPE), laptops, and other applications.

[0039] The wireless communication module includes a high-speed peripheral component interconnect (PCIe) interface. The PCIe interface is used to connect other devices or modules and is a full-duplex communication interface. When the wireless communication module acts as a master device, it connects to slave devices via the PCIe interface to control the slave devices for network connectivity or data transmission. When the wireless communication module acts as a slave device, it connects to a controller via the PCIe interface and is controlled by the controller to perform corresponding operations, such as establishing network connections or transmitting data, based on the controller's instructions / commands.

[0040] Terminal equipment, also known as a terminal, can refer to various forms of user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, user terminal, wireless communication equipment, user agent, or user device. Terminal equipment can also be cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle equipment, wearable devices, terminal equipment in 5G networks, or terminal equipment in future public land mobile networks (PLMNs), etc.

[0041] (2) Packaging type of wireless communication module Packaging refers to the process of physically encapsulating the core circuits (such as chips, power management units, etc.) inside a wireless communication module through specific processes and structures to form a physical functional component with standardized appearance, size, pin definitions, and connection methods. Packaging facilitates the integration and application of wireless communication modules in different terminal devices.

[0042] Wireless communication module package types include, but are not limited to, NGFF and LGA. NGFF packages can also be called M.2 packages; wireless communication modules in M.2 packages can be inserted into the M.2 slot of the development board for connection. LGA packaged wireless communication modules can be connected to the development board by soldering.

[0043] (3) Verification of the wireless communication module Verification of a wireless communication module refers to the process of testing and verifying the functionality of the module by building a suitable hardware platform (such as a development board) to ensure that the wireless communication module can stably and reliably perform its functions when applied in terminal devices. The hardware platform can be a development board, which includes circuitry for verifying the module's functionality.

[0044] Setting up a compatible development board can be understood as: designing a development board that matches the package type and function of the wireless communication module, or designing a development board that can verify a function of a wireless communication module of a certain package type. For example, development board a is designed to verify the control function of an M.2 package type wireless communication module as a master device. Development board b is designed to verify the control function of an LGA package type wireless communication module as a master device. Development board c is designed to verify the module function of an M.2 package type wireless communication module as a slave device. Development board d is designed to verify the module function of an LGA package type wireless communication module as a slave device.

[0045] It is evident that multiple development boards need to be designed to verify the different functions of wireless communication modules with different packaging types, resulting in a wide variety of development board types and high R&D costs.

Alternatively, the first wireless communication module 100 is an LGA package type wireless communication module, and the second wireless communication module 200 is an M.2 package type wireless communication module.

This approach is advantageous for verifying the control function of either the first wireless communication module 100 or the second wireless communication module 200 when it acts as the master control device, based on data transmission from slave devices.

[0053] Optionally, at least one slave device 400 can be a wireless fidelity (WIFI) module or a cellular communication module.

[0057] Optionally, the hardware-based control of the switch circuit 300 can be achieved by controlling the connection or disconnection between the interfaces in the switch circuit 300 through level signals (such as high level and low level). Optionally, the software-based control of the switch circuit 300 can be achieved by sending instructions to the switch circuit 300 through a software program to control the connection or disconnection between the interfaces in the switch circuit 300.

[0058] As can be seen, in this embodiment, the first wireless communication module 100 or the second wireless communication module 200 can control at least one slave device 400 based on the switch circuit 300. The first wireless communication module 100 or the second wireless communication module 200 can also be controlled by the controller 500 as a slave module based on the switch circuit 300. This facilitates verifying the functions of the first wireless communication module 100 or the second wireless communication module 200 (such as control functions or module functions as slave modules) in the same verification circuit, thereby reducing the types of development boards used for verifying module functions when applying this verification circuit to the development board.

[0081] in, Figure 3For details regarding the verification circuit shown, please refer to [link / reference]. Figure 1 The relevant description of the verification circuit shown will not be repeated here.

[0082] Optionally, the first switch 310, the second switch 320, and the third switch 330 can be high-speed differential switches. In this embodiment, the use of high-speed differential switches in the switching circuit 300 helps to ensure the accuracy of the signals transmitted by the circuit.

[0083] Optionally, the first switch 310, the second switch 320, and the third switch 330 can be double-pole double-throw analog switches.

[0084] As can be seen, in this embodiment, the first wireless communication module 100 or the second wireless communication module 200 can control the first slave device 410 based on the first switch 310, the second switch 320, and the third switch 330. It can also control the second slave device 420, and allow the first wireless communication module 100 or the second wireless communication module 200 to act as a slave module controlled by the controller 500. This facilitates verifying the functions of the first wireless communication module 100 or the second wireless communication module 200 (such as control functions or module functions as a slave module) in the same verification circuit, thereby reducing the number of development boards used for verifying module functions when applying this verification circuit to the development board.

[0085] Optionally, the signal lines on the development board using the above verification circuit are paired. Paired signal lines can be understood as: the wires transmitting the same signal consist of a positive polarity signal line and a negative polarity signal line; for example, the transmit signal line consists of a transmit positive polarity signal line and a transmit negative polarity signal line. This approach helps improve the signal's anti-interference capability, thereby improving the accuracy of the verification module's function.

[0086] Optionally, the development board using the above verification circuit should have consistent routing requirements. Routing refers to the wires connecting the pins of different components on the development board. Consistent routing requirements can include consistent spacing between wires, consistent impedance between wires, etc. This approach helps improve signal interference immunity, enhances signal transmission stability, and ensures the accuracy of verification results.
