[0044] The present application is applied to the scenario of testing aging equipment and performing aging detection on aging equipment. For each different DUT (device under test), the present application will periodically perform edge detection on the aging status signal of the device under test according to the preset duration and sampling accuracy, so as to determine whether there is a signal jump within the preset duration, so as to determine whether the device under test has completed the aging test based on whether a signal jump occurs.

[0045] Next, the technical solution of the present application is described with specific embodiments.

[0046] Example 1

[0047] Figure 1 A flow chart of an aging status signal detection method according to an embodiment of the present application is shown. Exemplarily, the aging status signal detection method includes the following steps:

[0048] Step S100: acquiring the aging status signal of the device under test in real time according to the detection cycle.

[0049] The device under test is a device that needs to undergo aging testing, such as various chips and other computing components or units.

[0050] The aging status signal is a status signal related to the aging status of the device under test. The aging status signal is a level signal, which is either a high level or a low level, wherein a high level is recorded as 1 and a low level is recorded as 0.

[0051] The detection cycle is a preset shorter time, such as 0.5 milliseconds, which means that the aging status signals are acquired in sequence every 0.5 milliseconds.

[0052] In this embodiment, a computer device equipped with an FPGA (programmable gate array) can be used as a detection device to detect the aging status information of the device under test, wherein the device under test can be connected to the computer device serving as the detection device through a serial port to obtain an aging status signal.

[0053] Step S200: performing edge detection on the aging status signal within a preset time period, and saving the detection result.

[0054] The preset duration is the duration set for a round of testing and can be set in advance before the test.

[0055] For example, the preset time length can be 10 seconds, which means that the edge detection of the aging status signal of the device under test is performed in a cycle of 10 seconds. During this period, the aging status signal of the device under test is continuously collected for 10 seconds, and the corresponding edge detection operation is performed to finally obtain a detection result. The detection result indicates the detection result of the edge detection within these 10 seconds, which is used to indicate whether there is a signal jump condition within these 10 seconds.

[0056] The above detection cycle and preset duration are parameters configured at the beginning and will not change in the subsequent detection process.

[0057] Specifically, the edge detection process of this embodiment is as follows: Figure 2 As shown, including:

[0058] Step S210, when the aging status signal is acquired for the first time, the aging status signal is logically ORed with 0 to obtain first data, and the aging status signal is logically ANDed with 1 to obtain second data.

[0059] In each round of edge detection, there is a time when the aging status signal is obtained for the first time. At this time, as the first aging status signal, its processing is different from that of subsequent aging status signals.

[0060] The aging status signal and 0 are logically ORed to obtain first data, and the aging status signal and 1 are logically ANDed to obtain second data.

[0061] For example, if the first aging status signal is at a high level, that is, 1, then the first data is 1 and the second data is also 1. If the first aging status signal is at a low level, that is, 0, then the first data is 0 and the second data is also 0.

[0062] At this time, the first data and the second data are two state data. For the convenience of storage, the two data can be concatenated and saved. For example, the first data is placed in the low position and the second data is placed in the high position to form a 2-bit signal data.

[0063] It can be understood that when the first aging status signal is at a low level, the signal data is 00, and if it is at a high level, the signal data is 11.

[0064] Step S220, whenever a new aging status signal is obtained, the new aging status signal and the first data are OR-calculated to obtain updated first data, and the new aging status signal and the second data are AND-calculated to obtain updated second data.

[0065] Then, the operation of step S100 is repeatedly performed to obtain a plurality of new aging status signals. Each time a new aging status signal is obtained, a logic OR calculation is performed with the first data and a logic AND calculation is performed with the second data, and then the first data and the second data are updated.

[0066] A specific situation indicating the change of aging status signal data is shown in the following table:

[0067] Aging status signal Second data First Data 1 1 1 1 1 1 0 0 1 1 0 1

[0068] The first row of data is the aging status signal obtained for the first time in the current detection round. The table shows the changes in the first data and the second data caused by four signal acquisitions when the aging status signal acquired for the first time is at a high level.

[0069] Correspondingly, when the aging status signal collected for the first time is at a low level, the corresponding data changes are shown in the following table:

[0070] Aging status signal Second data First Data 0 0 0 0 0 0 1 0 1 0 0 1

[0071] Combining the first two rows of the two tables, it can be seen that if the subsequent aging status signal is the same as the initial aging status signal, the first data and the second data will not change. When an electrical frequency jump occurs, the first data and the second data will change, and no matter how the level changes thereafter, they will not change. It can be seen that this change rule is that the signal data composed of the first data and the second data can be used to indicate whether a level jump occurs within the preset time length.

[0072] Step S230, repeatedly performing the operation of obtaining a new aging status signal each time until a preset time period is reached, and saving the latest first data and second data as the detection result.

[0073] Repeat the operation of step S220 to update the first data and the second data in real time. When the preset time is reached, it means that the current detection round time has expired and the current round of detection is completed. At this time, the signal data composed of the latest first data and second data is the detection result.

[0074] The test results will be saved for easy inspection.

[0075] It is understandable that in order to determine whether the device under test has completed aging, the above test requires multiple rounds of testing to determine. Therefore, after completing a round of testing and saving the test results, the next round of testing will be started immediately, that is, the operation of step S100 will be executed again.

[0076] When a new round of testing is completed, the newly obtained test results will replace the originally saved test results to update the test results. In this way, when it is necessary to determine whether there is a signal jump based on the test results, the latest test results can be obtained.

[0077] In an optional embodiment, each time a new aging status signal is obtained, the obtained aging status signal can also be stored in a two-bit historical data; when the latest aging status signal is obtained, the historical data is shifted to a high position, and then the latest aging status signal is stored in a low position of the historical data; when the next round of detection is performed, the historical data is cleared.

[0078] For example, in the initial state, the historical data is 00, and then an aging status signal of 1 is detected, the historical data becomes 01, and then another aging status signal of 1 is detected, 01 is shifted one bit to the high position to become 10, and then the new aging status signal is stored in the low position, and the historical data becomes 11. By analogy, whenever a new aging status signal is detected, it can be stored in this way, so that the stored aging status signal can also reflect whether there is a jump, and retain the characteristics of high and low level signals.

[0079] It can be understood that the two historical data here record the aging status signal itself, rather than the processed first data and second data. Therefore, in the two historical data, the data in the high position is the aging status signal of the previous moment, and the data in the low position is the latest aging status signal at the current moment. The historical data is used to store the latest aging status signal. From the data, it is also possible to simply judge the change of the signal at the current moment. For example, 11 indicates that the signal between the two acquisition points is in a high level state, 10 indicates that the signal between the two acquisition points has a high-to-low level jump, and is currently in a low level; 01: indicates that the signal between the two acquisition points has a low-to-high level jump, and the current signal is in a high level state; 00: indicates that the signal between the two acquisition points is in a low level state. By monitoring 10 and 01, it can be determined how many level jumps occurred in the monitoring round. This is to facilitate the data collection needs of some test items. At the same time, it can also perform monitoring operations more carefully.

[0080] Step S300: determining, based on the detection result, whether there is a signal jump in the aging status signal within the preset time period.

[0081] According to the signal change rules shown in the above two tables, it can be seen that when a signal jump occurs, the values ​​of the first data and the second data will change to 1 and 0 respectively, and then the two values ​​cannot be changed regardless of whether the aging status signal is high or low. Therefore, when the first data and the second data are not equal, it means that the aging status signal of the device under test has jumped.

[0082] When the first data and the second data are both 1 or both 0, it means that no signal jump has occurred within the preset time length, and it can be known that if both data are 1, it means that within the preset time length, the aging status signal has been at a high level, and if both data are 0, the aging status signal has been at a low level.

[0083] In one scenario, when the device under test starts the aging test, the detected aging status signal will be in a high or low steady state. As the test continues, when a signal jump is detected, it can be determined that the aging test of the device under test is completed.

[0084] In another scenario, the aging status signal collected from the device under test is a pulse signal. Only after the aging test of the device under test is completed, the signal will stabilize at a constant level. Therefore, whether the aging test of the device under test is completed can be determined by whether there is a signal jump. In other words, when a signal jump is found, it can be determined that the aging test of the device under test has not been completed. When the signal is found to be stable, it can be considered that the aging test may be completed at this time, so further judgment can be made.

[0085] The above two scenarios arise due to different devices under test and customer needs, and the conditions for ultimately determining whether the aging test of the device under test is completed are therefore different. However, it can be understood that the detection results in the aging status signal detection method of this embodiment can indicate whether the signal is stable or changing within a certain period of time. Therefore, regardless of whether the final judgment condition is level stability or level jump, the method of this embodiment can perform adaptive processing.

[0086] Among them, because different devices under test have different configurations and requirements, whether the aging test is completed needs to be determined in combination with specific device data, such as customer needs and device parameters.

[0087] In addition, the aging status signal may not have a signal jump in the current round, but a signal jump may occur in the next detection round. Therefore, a detection condition can be set for whether the level is stable. For example, if the detection results of several consecutive rounds are the same stable signal, it is determined that the aging status signal is stable, and then the aging test is performed to determine whether it is completed.

[0088] The detection result is the data formed by combining the first data and the second data, and the form can be that the first data is in the low position and the second data is in the high position, or vice versa. When the first data is in the low position and the second data is in the high position, the detection result is 01, indicating that a signal jump has occurred. When the first data is in the high position and the second data is in the low position, the detection result is 10, indicating that a signal jump has occurred.

[0089] In general, the aging status signal detection process of this embodiment is as follows: Figure 3 As shown in the figure, the parameters are configured at the beginning to determine the detection cycle and the duration of each round of detection. Then, based on these two data, periodic signal detection is performed and the detection results are output. Multiple rounds of detection will be repeated before the current device detection is completed. After the current device detection is completed, it will stop completely. When a new device detection is performed, the above operations will be repeated. It can be seen that no matter what kind of device is being tested, it is suitable for the following Figure 3 The cycle process is shown.

[0090] The aging status signal detection method of this embodiment performs logical calculation processing on the aging status signal to obtain two calculation data, and determines whether there is a signal jump within a preset time period based on the two data, thereby assisting in determining whether the aging test of the device under test has been completed. In the test process, the test results and the aging status signals collected twice recently will also be recorded, so that when determining whether there is a jump signal based on the test results, the actual state of the current aging status signal can also be determined, thereby ensuring the comprehensiveness of the test results and facilitating aging tests directly based on the aging status signal. At the same time, the method of this embodiment has a wide range of applications, so it can save time and labor costs, provide an efficient, reliable, and economical solution for aging testing, and significantly improve the efficiency and quality of the test.
