[0076] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0077] In practical applications, when performing load start-up and load power-off tests on each VR group on the server motherboard, two load lines are soldered to the output end, with the positive and negative terminals connected to the positive and negative terminals of the electronic load, respectively. At the same time, signal lines are soldered to the output capacitor. The output signal is led to an oscilloscope through a probe, and the output voltage waveform is displayed on the oscilloscope. The PSU is manually powered on and off to perform load start-up and load power-off tests on the output voltage.

[0078] Since an electronic load is used to simulate the back-end load of the VR (Voltage Regulation, for the voltage regulator of the power chip), the electronic load and the motherboard are connected by wires. Due to structural limitations, the wires are often quite long. The longer the wires are, the greater the ESL (parasitic inductance) fed back to the power chip, which will result in a larger undershoot measured by the oscilloscope. The only solution is to repeatedly shorten and thicken the wires for testing until the undershoot can no longer be improved.

[0079] The manual testing of power chips described above is inefficient due to the lack of quick and suitable solutions provided by individual differences in experience.

[0080] Reference Figure 1 The diagram illustrates a flowchart of a power chip detection method provided in an embodiment of the present invention, which may specifically include the following steps:

[0081] Step 101: Generate a first control command for the start capacitor control module;

[0082] Step 102: Based on the first control command, determine the number of first capacitors of the first capacitor in the circuit state through the start capacitor control module.

[0083] Step 103: Detect the power chip based on the first capacitor quantity and generate first detection data for the power chip.

[0084] In a specific implementation, the power chip of this embodiment can be configured on a server, and the server can be configured with a corresponding load board. The load board can include a startup capacitor control module, and the startup capacitor control module can be configured with multiple first capacitors. The first capacitors can have a closed state and an open state. The startup capacitor control module of this embodiment can be used to control the first capacitors to be in a closed state or an open state, so as to simulate the load situation of the power chip when the server starts up and the load is powered off through the first capacitors in the closed state.

[0085] This invention can generate a first control command for the startup capacitor control module. Optionally, this invention can be applied to an automated testing application for power supply chips. This automated testing application can be loaded onto a computer PC. In practical applications, a computer PC refers to a multi-purpose computer of a size, price, and performance suitable for personal use. Desktop computers, laptops, mini-laptops, tablets, and ultrabooks are all personal computers. Universal Serial Bus (USB) is a serial bus standard and an input / output interface specification widely used in personal computers and mobile devices, and has expanded to other related fields such as photographic equipment, digital televisions (set-top boxes), and game consoles. The latest generation is USB4, with a transmission speed of 40 Gbit / s, three-segment voltage of 5V / 12V / 20V, a maximum power supply of 100W, and a new Type-C interface that allows reversible blind insertion.

[0086] In this embodiment of the invention, after generating a first control command for the start capacitor control module, the start capacitor control module determines the number of first capacitors in the circuit state based on the first control command, and detects the power chip based on the number of first capacitors, so as to generate first detection data for the power chip.

[0087] For example, a computer PC can connect to the load board via a USB interface. The computer PC can generate a first control command for the startup capacitor control module and send the first control command to the load board via the USB interface. The load board can be configured with a startup capacitor control module, which can have multiple corresponding softstart capacitors SS. The startup capacitor control module can control the softstart capacitors SS to be in a closed state or an open state based on the first control command, and determine the first number of softstart capacitors SS in the closed state. After determining the number of softstart capacitors in the closed state, the softstart capacitors SS in the closed state can be controlled according to the first number of capacitors to simulate the load conditions of the power chip when the server starts up and the load is de-energized, and generate detection data characterizing whether the output voltage of the power chip monotonically increases or decreases when the server starts up and the load is de-energized.

[0088] Of course, the above examples are merely illustrative. Those skilled in the art can use any other detection results as the first detection data for the power chip, and the embodiments of the present invention do not impose any limitations on this.

[0089] In this embodiment of the invention, a first control command is generated for the startup capacitor control module; based on the first control command, the startup capacitor control module determines the number of first capacitors in the path state; based on the number of first capacitors, the power chip is detected, and first detection data for the power chip is generated. This avoids manually cutting wires to detect the power chip, thereby improving the detection efficiency of the power chip.

[0090] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0091] In an optional embodiment of the present invention, the load board includes an output load control module, the output load control module being configured with a plurality of second capacitors, the second capacitors having corresponding circuit states, and further comprising:

[0092] Generate a second control command for the output load control module;

[0093] Based on the second control command, the number of second capacitors in the second capacitor in the path state is determined by the output load control module;

[0094] The second capacitor, based on the second number of capacitors, detects the power chip and generates second detection data for the power chip; the first detection data is used to characterize whether the output voltage of the power chip is monotonic when the server starts up and when the load is de-energized; the second detection data is used to characterize the overshoot parameter and / or undershoot parameter of the output voltage of the power chip when the server starts up and when the load is de-energized.

[0095] In practical applications, the testing of power supply chips mainly includes two aspects: first, whether the output voltage is not monotonic during load startup and load de-energization; second, whether the overshoot or undershoot of the output voltage is too large during load startup and load de-energization, that is, whether the overshoot or undershoot parameters of the output voltage exceed the normal operating voltage of the load.

[0096] refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a load board provided in an embodiment of the present invention.

[0097] In a specific implementation, the load board 200 of this embodiment may include a startup capacitor control module 201 and an output load control module 203. The startup capacitor control module 201 is configured with a plurality of first capacitors 202, and the output load control module 203 is configured with a plurality of second capacitors 204. The second capacitors 204 may be multiple capacitor groups, and the capacitor groups may be composed of multiple soft-start capacitors.

[0098] For example, the first capacitor 202 and the second capacitor 204 can be soldered to the corresponding pins of the VR under test, respectively. The load board can be configured with a startup capacitor control module 201 and an output load control module 203. A computer PC can be connected to the load board via a USB interface. The computer PC can generate a first control command for the startup capacitor control module 201 and a second control command for the output load control module 203, and send the first and second control commands to the load board via the USB interface. The startup capacitor control module can have multiple corresponding first capacitors 202. The startup capacitor control module can control the first capacitors 202 to be in a closed state or an open state based on the first control command, and determine the number of first capacitors 202 in the closed state. After determining the number of first capacitors in the closed state, the load board can be controlled according to the number of first capacitors. The first capacitor 202, which is in a closed-circuit state, simulates the server's operation during load startup and power failure, generating detection data characterizing whether the power chip's output voltage monotonically increases or decreases during load startup and power failure. The output load control module 203 can have multiple corresponding second capacitors 204. The output load control module 203 can control the second capacitors 204 to be in a closed-circuit state or an open-circuit state based on a second control command, and determine the number of second capacitors 204 in the closed-circuit state. After determining the number of second capacitors in the closed-circuit state, the second capacitors 204 in the closed-circuit state can be controlled according to the number of second capacitors to simulate the server's operation during load startup and power failure, generating overshoot parameters and / or undershoot parameters characterizing the power chip's output voltage during load startup and power failure.

[0099] In this embodiment of the invention, a second control command is generated for the output load control module; based on the second control command, the output load control module determines the number of second capacitors in the path state; based on the number of second capacitors, the power chip is detected, and second detection data for the power chip is generated; the first detection data is used to characterize whether the output voltage of the power chip is monotonic when the server starts up and when the load is de-energized; the second detection data is used to characterize the overshoot parameter and / or undershoot parameter of the output voltage of the power chip when the server starts up and when the load is de-energized. This achieves the simultaneous detection of whether the output voltage of the power chip is monotonic during load startup and load de-energization, and also determines whether the overshoot or undershoot parameter of the output voltage is excessive, i.e., whether the overshoot or undershoot parameter exceeds the normal operating voltage of the load, thereby further improving the detection efficiency for the power chip.

[0100] In an optional embodiment of the present invention, the method is applied to an automated test application for the power supply chip, the automated test application being configured with a corresponding application programming interface, the power supply chip being configured with a corresponding voltage regulator, and prior to the step of generating a first control command for the startup capacitor control module, the method further includes:

[0101] The application programming interface is invoked based on a user request to read the initial voltage value for the power supply chip through the voltage regulator and determine the preset current value for the power supply chip.

[0102] In practical applications, to further achieve automated testing of power supply chips, embodiments of this invention can be applied to automated testing applications. These applications can be loaded onto a PC and are configured with corresponding Application Programming Interfaces (APIs). APIs are predefined functions designed to provide applications and developers with the ability to access a set of routines based on certain software or hardware, without needing to access the source code or understand the details of the internal workings. The power supply chip can be configured with a corresponding voltage regulator (VR).

[0103] For example, the automated test application may include a test module and a test result display module. After the load board is connected to the PC via a USB interface and electrically connected to the power chip, the automated test application can call resources based on the application programming interface (API) on the operating system, run the automated test application to obtain the voltage of the VR under test, and set the load current according to a preset value, thereby realizing the subsequent determination of the VR load terminal resistance through the initial voltage value and the preset current value, so as to control the circuit state of the first capacitor and / or the second capacitor.

[0104] In this embodiment of the invention, by calling the application programming interface based on a user request, the voltage regulator reads the initial voltage value for the power chip and determines the preset current value for the power chip. This provides a prior condition for subsequently determining the VR load terminal resistance based on the initial voltage value and the preset current value, so as to control the path state of the first capacitor and / or the second capacitor, thereby further improving the detection efficiency for the power chip.

[0105] In an optional embodiment of the present invention, the step of generating a first control command for the start-up capacitor control module includes:

[0106] Based on the initial voltage value and the preset current value, a first control command is generated for the start capacitor control module.

[0107] For example, when the target data to be detected is whether the output voltage of the power chip is monotonic when the server is under load and under load, the application programming interface (API) on the operating system can be used to call resources, run an automated test application to obtain the voltage of the VR under test, set the load current according to a preset value, and generate a first control command for the start capacitor control module based on the voltage value and the load current, so as to call the start capacitor control module to open the start capacitor control circuit and control the circuit state of the first capacitor.

[0108] In this embodiment of the invention, a first control command for the start-up capacitor control module is generated based on the initial voltage value and the preset current value, thereby realizing the automatic generation of the first control command and further improving the detection efficiency of the power chip.

[0109] In an optional embodiment of the present invention, the step of generating a second control command for the output load control module includes:

[0110] Based on the initial voltage value and the preset current value, a second control command is generated for the output load control module.

[0111] For example, when the target data to be detected is whether the overshoot / undershoot parameters of the power chip output voltage meet the preset requirements when the server is powered on and powered off, resources can be called based on the application programming interface (API) on the operating system to run an automated test application to obtain the voltage of the VR under test, set the load current according to the preset value, and automatically generate a second control command for the output load control module based on the voltage value and the load current to call the start capacitor control module to open the start capacitor control circuit and control the circuit state of the second capacitor.

[0112] In this embodiment of the invention, a second control command for the output load control module is generated based on the initial voltage value and the preset current value, thereby realizing the automatic generation of the second control command and further improving the detection efficiency of the power chip.

[0113] In an optional embodiment of the present invention, the server is configured with a corresponding oscilloscope, the load board includes an enable control module, and the step of detecting the power chip based on the first capacitor quantity and generating first detection data for the power chip includes:

[0114] The power supply chip is detected by the power supply control module based on the first capacitor quantity, and the first detection data for the power supply chip is generated by the oscilloscope.

[0115] refer to Figure 2 The load board in this embodiment of the invention may also be configured with an enable terminal control module 205.

[0116] refer to Figure 3 , Figure 3 This is a schematic diagram of a power chip testing system provided in an embodiment of the present invention. For example, the power chip testing system may include a computer PC, a load board, a motherboard under test configured on a server, and an oscilloscope. The oscilloscope can be connected to the computer PC through a General-Purpose Interface Bus (GPIB). GPIB is a bus that connects devices and computers. Most desktop instruments connect to a computer via GPIB cables and GPIB interfaces. The PC can connect to a load board via a USB interface. The load board can connect to the motherboard under test (DUT) via signal cables and / or wires. The DUT can connect to an oscilloscope probe via an oscilloscope. When the target data to be tested is whether the power chip output voltage is monotonic during load startup and load shutdown, resources can be called based on the operating system's application programming interface (API) to run an automated test application to obtain the voltage of the VR under test. The load current is set according to a preset value, and based on this voltage value and load current, a first control command is generated for the startup capacitor control module to call the startup capacitor control module to open the startup capacitor control circuit and control the circuit state of the first capacitor. The automated test application can call internally defined functions to automatically call the enable control module 205. The system architecture is built based on the QThread standard library under the PyQt5 graphical interface framework to pull the level of the enable control module 205 high or low. During this process, the computer PC can read the first test data of the power chip from the oscilloscope, thereby realizing automated testing of the power chip.

[0117] In this embodiment of the invention, the power supply chip is detected by the power supply control module based on the first capacitor of the first capacitor quantity, and the first detection data for the power supply chip is generated by the oscilloscope, thereby further improving the automation of power supply chip detection and further improving the detection efficiency of power supply chip.

[0118] In an optional embodiment of the present invention, the step of detecting the power supply chip based on the second capacitance number and generating second detection data for the power supply chip includes:

[0119] The power supply chip is detected by the power supply control module based on the second capacitor quantity, and second detection data for the power supply chip is generated using the oscilloscope.

[0120] For example, when the target data to be detected is whether the overshoot / undershoot parameters of the power chip output voltage meet preset requirements when the server is under load and under load, resources can be called based on the application programming interface (API) on the operating system to run an automated test application to obtain the voltage of the VR under test, set the load current according to the preset value, and generate a second control command for the output load control module based on the voltage value and load current to call the output load control module to start the capacitor control circuit and control the circuit state of the second capacitor. The automated test application can call the internally defined function to automatically call the enable control module 205. The system architecture is built based on the QThread standard library under the PyQt5 graphical interface framework to enable the control module 205 to pull up or lower the level. During this process, the computer PC can read the second detection data of the power chip from the oscilloscope, thereby realizing automated testing of the power chip.

[0121] In this embodiment of the invention, the power supply chip is detected by the power supply control module based on the second capacitor number, and the second detection data for the power supply chip is generated by the oscilloscope, thereby further improving the automation of power supply chip detection and further improving the detection efficiency of power supply chip.

[0122] In an optional embodiment of the present invention, it further includes:

[0123] When the first detection data is different from the first preset value, a third control command is generated for the start capacitor control module;

[0124] Based on the third control command, the number of third capacitors in the first capacitor in the circuit state is determined by the start capacitor control module; the number of third capacitors is different from the number of first capacitors.

[0125] The first capacitor, based on the third number of capacitors, detects the power chip and generates third detection data for the power chip; the third detection data is used to characterize whether the output voltage of the power chip is monotonic when the server is under load and under load power failure.

[0126] When the second detection data is different from the second preset value, a fourth control command is generated for the output load control module;

[0127] Based on the fourth control command, the output load control module determines the number of fourth capacitors in the second capacitor in the path state; the number of fourth capacitors is different from the number of second capacitors.

[0128] The second capacitor, based on the fourth number of capacitors, detects the power chip and generates fourth detection data for the power chip; the fourth detection data is used to characterize the overshoot parameter and / or undershoot parameter of the power chip output voltage when the server is started and powered off.

[0129] In practical implementation, if a test fails—that is, when the first test data differs from the first preset value, or when the second test data differs from the second preset value—a preset problem can be selected from the automated testing application to automatically debug the problem. For example, when selecting the problem of non-monotonic output during load startup and load power failure, automatic debugging is initiated, generating a third control command for the startup capacitor control module; based on the third control command, the startup capacitor control module determines the number of third capacitors in the circuit state; the number of third capacitors differs from the number of first capacitors; based on the number of third capacitors, the power chip is detected, and third test data for the power chip is generated; the third test data can be test data used to characterize whether the power chip output voltage is monotonic during load startup and load power failure. For example, when encountering issues with excessive overshoot and undershoot in the output voltage during load startup and load power failure, automatic debugging is initiated, generating a fourth control command for the output load control module. Based on this fourth control command, the output load control module determines the number of fourth capacitors in the second capacitor's on-state. This number of fourth capacitors differs from the number of second capacitors. Based on this fourth number, the second capacitors detect the power supply chip, generating fourth detection data for the power supply chip. This fourth detection data can characterize the overshoot and / or undershoot parameters of the power supply chip's output voltage during load startup and load power failure.

[0130] In this embodiment of the invention, when the first detection data differs from a first preset value, a third control command is generated for the startup capacitor control module; based on the third control command, the startup capacitor control module determines the number of third capacitors of the first capacitor in the circuit state; the number of third capacitors differs from the number of first capacitors; based on the number of third capacitors, the first capacitors detect the power chip, and third detection data is generated for the power chip; the third detection data is used to characterize whether the output voltage of the power chip is monotonic when the server is under load startup and under load power failure; when the second detection data differs from a second preset value, a third control command is generated for the startup capacitor control module. The output load control module issues a fourth control command; based on the fourth control command, the output load control module determines the fourth number of the second capacitor in the path state; the fourth number of capacitors is different from the second number of capacitors; based on the second capacitors of the fourth number of capacitors, the power chip is detected, and fourth detection data for the power chip is generated; the fourth detection data is used to characterize the overshoot parameter of the power chip output voltage when the server starts up and the load is powered off, and / or the undershoot parameter is switched by the circuit, thereby enabling the automated test application to automatically debug a suitable capacitor group when the test fails, further improving the detection efficiency for the power chip.

[0131] To enable those skilled in the art to better understand the embodiments of the present invention, a complete example is used below to illustrate the embodiments of the present invention.

[0132] refer to Figure 3 , Figure 3 This is a schematic diagram of a power chip testing system provided in an embodiment of the present invention. For example, the power chip testing system may include a computer PC, a load board, a motherboard under test configured on a server, and an oscilloscope. The oscilloscope can be connected to the computer PC via a general purpose interface bus (GPIB). The PC can be connected to the load board via a USB interface. The load board can be connected to the motherboard under test via signal lines and / or wires. The motherboard under test can be connected to the oscilloscope via an oscilloscope probe.

[0133] refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a load board provided in an embodiment of the present invention.

[0134] In a specific implementation, the load board 200 of this embodiment of the invention may be configured with a startup capacitor control module 201, an output load control module 203, and an enable terminal control module 205. The startup capacitor control module 201 is configured with a plurality of first capacitors 202, and the output load control module 203 is configured with a plurality of second capacitors 204. The second capacitors 204 may be multiple capacitor groups, which may consist of multiple soft-start capacitors. Before testing, the enable terminal control module 205EN, the first capacitors 202, the second capacitors 204, and the load group Vout may be soldered to the enable terminal pin ENPin, the capacitor pin SSPin, and the load component pin Vout Pin of the VR under test, respectively.

[0135] refer to Figure 4 , Figure 4 This is a schematic diagram of an automated testing application provided in an embodiment of the present invention. The automated testing application mainly includes a testing module 401 and a test result display module 402. After the test environment is set up, the total resistance of the VR load terminal on the motherboard can be set in the automated testing application. This total load resistance can be determined by the load voltage and load current. According to the set total resistance, a suitable load group is automatically selected, the automated test is started, and the start capacitor control module and the output load control module are called to disconnect the start capacitor control line and the load board capacitor group until the test is completed.

[0136] If a test fails, automatic troubleshooting can be performed by selecting the problem. Selecting the issue of non-monotonic output during load startup and load power-off will initiate automatic troubleshooting, calling the startup capacitor control module to automatically verify different SS capacitors until the waveform monotonicity problem is resolved. The specific solution will then be displayed in the test results.

[0137] When encountering issues with excessive voltage spikes or dips during load startup and power failure, automatic debugging is initiated. This involves calling up the capacitor bank in the output load control module, switching circuits, and automatically adjusting to find a suitable capacitor bank until the problem is resolved. The specific solution is then displayed in the test results.

[0138] In practice, the automated test can be started via a PC operating system by clicking "Start Automated Test." Resource calls are made using the Windows system API interface to run the automated test software, which automatically acquires the voltage of the VR under test. The load current is set, and the system automatically calls the EN control module using internally defined functions. The system architecture is built based on the QThread standard library under PyQt5. The system can control the EN level (high and low) and oscilloscope operation to achieve automated testing.

[0139] refer to Figure 5 , Figure 5This is a flowchart illustrating a power chip testing method provided in this embodiment of the invention. First, a load start-up and load power-off test environment for the output voltage is set up. The motherboard, oscilloscope, and load board are connected as required. The oscilloscope is connected to the PC via GPIB, and the load board is connected to the PC via USB, allowing the PC to operate the oscilloscope and control the load board. After powering on the motherboard, the online operating system is opened, the test conditions (i.e., the load resistance setting) are set, and automated testing is started. If a test fails, automatic debugging is initiated until a solution is found.

[0140] By utilizing automated testing and online automatic debugging, the above methods can avoid misjudgments caused by testing methods, quickly identify solutions, avoid repeated debugging and testing, and are easy to operate, which can effectively improve work efficiency and testing accuracy.
