[0002] Integrated chips (such as memory chips, power management chips, etc.) are core components of high-voltage power products, and their performance seriously affects the user experience of their application products. Therefore, in order to ensure the high reliability of integrated chips, power-off tests are often performed on the products to which they are applied during the startup phase while testing the performance of the chips themselves. For example, products powered by 12V~24V power supplies such as OTT, TV, and projectors all have integrated chips. By performing power-off tests on high-voltage power products such as OTT and TV during the startup phase, the performance of integrated chips can be better evaluated. However, in the actual testing process, timing relays are often used to manually test each high-voltage power product, and timing relays can often only be tested for a fixed duration, resulting in low reliability and low test efficiency. Therefore, there is an urgent need for a method to achieve efficient testing of integrated chips and improve the reliability of test results. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0011] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art belonging to the technical field of the present application.

The terms "first", "second", "third", "fourth", etc. (if present) in the specification of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order.

[0012] In addition, the described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the present disclosure.

[0013] Reference Figure 1 As shown, according to an embodiment of the present application, a system for integrated chip power-off testing includes a power-on device; wherein the power-on device includes: A wiring terminal having a plurality of power supply channels arranged thereon; a first end of each power supply channel being connected to a power supply, a second end of each power supply channel supporting connection to a product to be tested, and each product to be tested being integrated with an integrated chip; Control module, the control module performs the following steps: Setting the physical state of each power supply channel to disconnected so that the products to be tested connected to each power supply channel are in a power-off state; wherein each product to be tested is integrated with an integrated chip; According to the preset test sequence, traverse the current round of each product to be tested; Obtain the power-on test duration of each product under test traversed in the current round, turn on the power supply channel corresponding to the traversed product under test for the corresponding power-on test duration and then disconnect it, so that the power-on test duration of the traversed product under test reaches the corresponding power-on test duration; After all products under test have completed the current round of traversal, the next round of traversal is performed again on each product under test in the test order, wherein the power-on test duration obtained in the current round of traversal for the same product under test is different from the power-on test duration obtained in the previous round of traversal.

[0014] It is understandable that the products to be tested are high voltage power products such as OTT and TV; the products to be tested on the same terminal block have the same type of integrated chips.

[0015] It is understandable that the embodiment of the present application does not limit the number of connection terminals, nor does it limit the number of power supply channels on the connection terminals. Those skilled in the art can selectively set according to actual needs.

[0016] The embodiments of the present application do not limit how to realize the conduction and disconnection of each power supply channel. For example, a relay or switch can be set for each power supply channel, so that the conduction and disconnection of each power supply channel can be realized. When the power supply channel is turned on, the power supply can provide power to the product under test through the turned-on power supply channel, and the product under test can be powered on normally.

[0017] The power-on test duration represents the duration of the chip startup phase, so that power-off testing can be performed on each product under test during the startup phase.

[0018] The embodiments of the present application do not limit the number of test rounds, and those skilled in the art can selectively set them according to actual needs, such as setting the cumulative test duration or the cumulative number of tests. When one of the above is met, the power-on test of the product to be tested corresponding to the integrated chip can be terminated. After the power-on test is completed, if the product to be tested can still start normally, it means that the integrated chip is normal and meets the performance requirements.

[0019] The test sequence can be selectively set according to actual needs, and the embodiments of the present application do not limit it.

[0020] The duration of power-on tests in different rounds for the same product under test is different, so that step-by-step power-on tests can be performed on each product under test.

[0021] It is understandable that the control module may be an MCU or a PLC chip, and after the above method is burned into it in a program form, power-on testing of multiple products to be tested can be implemented.

[0022] It is understandable that the type of the product to be tested connected to each power supply channel is different.

[0023] By setting the type of each product to be tested to be different, the performance of the same type of integrated chip applied to different products can be further ensured, thereby further ensuring the reliability of the test results.

[0024] For example, refer to Figure 1 As shown, there are n products to be tested, namely product 1 to product n to be tested, the live wires of product 1 to product n to be tested are electrically connected to the power supply through the wiring terminals, the control module is electrically connected to the wiring terminals, and the control module controls the conduction state of the power supply channels of the wiring terminals connected to product 1 to product n to be tested respectively, so that product 1 to product n to be tested are turned on in sequence and the conduction time can be set according to program changes, thereby more flexibly realizing the power-on test of each product to be tested in the startup stage.

[0025] Reference Figure 2 As shown, according to a method for power-off testing of an integrated chip in an embodiment of the present application, the method is applied to a power-on device, the power-on device is provided with a wiring terminal, and a plurality of power supply channels are provided on the wiring terminal; the method comprises: Step S100, setting the physical state of each power supply channel to disconnect, so that the products to be tested connected to each power supply channel are in a power-off state; wherein each product to be tested is integrated with an integrated chip; Step S200: traverse the current round of each product to be tested according to a preset test sequence; Step S300, obtaining the power-on test duration of each product to be tested traversed in the current round, turning on the power supply channel corresponding to the traversed product to be tested for the corresponding power-on test duration and then disconnecting it, so that the power-on test duration of the traversed product to be tested reaches the corresponding power-on test duration; Step S400: After all products under test have completed the current round of traversal, the next round of traversal is performed again on each product under test in the test order, wherein the power-on test duration obtained by the same product under test in the current round of traversal is different from the power-on test duration obtained in the previous round of traversal.

[0026] Therefore, multiple products to be tested can be connected to the power supply through the corresponding power supply channels through the wiring terminals. At this time, by controlling the on and off of each power supply channel connected to the products to be tested, the products to be tested can be automatically powered on and off. And through the program control method, it is possible to more flexibly implement different power-on test durations for different products to be tested without changing the system connection relationship, thereby further ensuring the performance reliability of the integrated chip. Therefore, compared with the related art, the embodiment of the present application can realize automatic testing of multiple products to be tested with different power-on test durations, and the test is more flexible and efficient. At this time, the test results of the performance of the products to be tested are more reliable.

[0027] When the physical state of the power supply channel is disconnected, the product under test is disconnected from the power supply, so that each product under test can be in a power-off state in the initial state.

[0028] When starting the test, each product to be tested is tested one by one to ensure that the products to be tested do not affect each other, and the test results are more reliable. The test sequence can be selectively set according to actual needs, such as according to the number of the power supply channel or the number of the product to be tested. In this regard, the embodiment of the present application does not limit the test sequence.

[0029] When the power supply channel is turned on, the power supply can supply power to the product under test through the turned-on power supply channel, and the product under test starts power-on testing.

[0030] The power-on test duration is used to ensure that the product to be tested is in the power-on stage. The embodiment of the present application can set the power-on test duration according to actual needs. The power-on test duration of each product to be tested can be set differently or the same. In this regard, the embodiment of the present application does not limit how to set the power-on test duration.

[0031] The embodiment of the present application does not impose any restrictions on how to set the power-on test duration of each product to be tested in each round. It can be set in a fixed step-by-step manner. For example, an initial power-on test duration is set, and each time a new round of power-on test is performed, a fixed step is added to the power-on test duration of the previous round to obtain the power-on test duration of the current round.

[0032] It is understandable that the embodiments of the present application do not limit the termination conditions for whether to terminate the power-on test of all products to be tested. Technical personnel in this field can selectively set it according to actual needs, such as the number of test rounds is greater than the preset number of rounds, such as the cumulative duration of the test is greater than the preset duration.

[0033] For example, refer to Figure 3 As shown in the figure, taking the products to be tested as Y001, Y002, Y003, and Y004 as an example, the power-on test duration of each product to be tested is the same in the same round of power-on test. Figure 3 As shown, during the first round of power-on test, the power-on test duration of each product to be tested is set to t1, and during the second round of power-on test, the power-on test duration of each product to be tested is set to t2; during the first round of power-on test, firstly, the power supply channel corresponding to Y001 is closed to power on Y001, and Y001 is disconnected after t1 to power off Y001; then the same operation is performed on Y002, and when Y004 is also powered on for t1, the first round of testing is completed, and at this time, the second round of power-on test is started, and during the second round of power-on test, the test is re-started from Y001, as shown in FIG. Figure 3 As shown in the figure, the power-on test duration of Y001, Y002, Y003, and Y004 is all t2, and t2 is different from t1. This process is repeated until Y001, Y002, Y003, and Y004 all meet the preset test stop conditions.

[0034] It is understandable that, according to the preset test sequence, each product to be tested is traversed in the current round, including: Get the traversal time interval of the current round; the traversal time intervals of different rounds are different; In the current round, according to the test sequence, at each traversal time interval, the product under test that has not been powered on is regarded as the product under test traversed at the current moment.

[0035] It is understandable that the traversal time interval of each round is greater than the power-on test duration. At this time, by setting the traversal time interval, it can be ensured that each product to be tested will wait for a period of time after the corresponding power-on test duration is powered on before disassembling and testing the next product to be tested, thereby reducing the mutual influence between the products to be tested.

[0036] It is understandable that, according to the preset test sequence, each product to be tested is traversed in the current round, including: Get the pre-configured script file; Start reading from the first line of the script file in sequence to obtain the test instructions for each product to be tested.

[0037] By configuring the script, you can make the test more flexible. In this case, the test order is the order of the test instructions in the script.

[0038] It is understandable that obtaining the power-on test duration of each product to be tested traversed in the current round, and switching on the power supply channel corresponding to the traversed product to be tested for the corresponding power-on test duration and then disconnecting it includes: For each test instruction read, a connection instruction is issued to the target power supply channel corresponding to the test instruction, so as to supply power to the corresponding connected product under test through the target power supply channel; For each test instruction read, execute the power-on test duration waiting instruction in the test instruction; For each test instruction read, after the power-on test time waits for the instruction to be executed, a disconnection instruction is sent to the target power supply channel to make the target power supply channel stop supplying power to the corresponding product under test.

[0039] The power-on test duration waiting instruction defines the power-on test duration of the target power supply channel, which is used to make the control module wait for the power-on test duration before executing subsequent instructions.

[0040] It is understood that the method further comprises: Get the duration threshold; When the accumulated duration of the power-on test of each product under test meets the duration threshold, the power supply function of each product under test is verified to obtain a test result.

[0041] The power supply function verification is to keep the product under test powered on to determine whether the product under test can start successfully.

[0042] It is understood that the method further comprises: Change the connection relationship between each product under test and the power supply channel; and jump to the step of setting the physical state of each power supply channel to disconnected.

[0043] By changing the connection relationship between each product under test and the power supply channel, a more comprehensive test can be performed on the product under test, and the test result is more reliable.

[0044] It is understandable that the power-on device is also provided with an indicator light; before traversing the current round of each product to be tested according to a preset test sequence, the method further includes: Turn on the indicator light; When the accumulated duration of the power-on test of each product to be tested meets the duration threshold, the indicator light is turned off.

[0045] The embodiment of the present application does not limit the color of the lighted indicator light, such as red when lit, or green. By setting the indicator light, the tester can more intuitively determine whether the test is finished, and then start the performance test of the product to be tested.

[0046] For example, refer to Figure 4 As shown, the test method of the embodiment of the present application is described, wherein the wiring terminal can be connected to at least 8 products to be tested at the same time, and a maximum of 16 products to be tested. When multiple products to be tested are powered on step by step, the signal indicator light is turned on. At this time, the signal indicator light is red, and then the test script written using PCL software is loaded, wherein the power-on test duration in the test script is 1S, 2S~10S, and 10S~60S as a cycle. Among them, the power supply supports a supply voltage of 12~24V. The wiring terminal is 16-way, and the interface order of 1~16 is Y000~Y015. According to the set program, step by step power is turned on for one cycle, and then enter the next cycle; then the steps for each cycle are as follows: Step 1, starting from Y001, each product i to be tested is regarded as product i to be tested; for each product i to be tested, power is continuously supplied to product i to be tested for a certain period of time and then disconnected; when all products to be tested have completed a round of testing, jump to step 2; Step 2: Determine whether the number of test rounds meets the preset round number threshold, if not, jump to step 3; if yes, jump to step 4; Step 3: Update the power-on test duration of each product to be tested and jump to step 1; Step 4: Initialize the power-on test duration and the number of test rounds and jump to step 1 to start the next cycle.

[0047] Through the above steps, a stepper power-on device can be formed by using a power supply 220V to 12V~24V voltage regulator, a control module, and a terminal block combination. The stepper power-on program code can be programmed using PCL programming software and burned into the control module to implement a stepper power-on test of 8~16 products to be tested. When different types of products with the same working voltage (OTT, TV, projector) are connected after the test is completed, if the product still steps on the device normally, it means that the requirements are met.

[0048] The embodiment of the present application also provides an electronic device, the electronic device includes a memory and a processor, the memory stores a computer program, and the processor implements the above method when executing the computer program. The electronic device can be any intelligent terminal including a tablet computer, a car computer, etc.
