For example, if the Current Limit condition is 200 amperes (a) and the CPU maximum Current demand is 500A, the voltage stability between 200A and 500A cannot be tested when the Current Limit condition is used for testing, and thus the overall stability of VR power supply cannot be determined.

Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments herein without making any inventive effort are intended to fall within the scope of the present application.
The core of the application is to provide a testing method of VR power supply stability of CPU and related components, before testing the VR power supply stability, judging whether VR has current limiting function or not, and selecting corresponding test script to test by combining the judging result to determine the VR power supply stability.
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
With the continuous development of the internet, various services have higher and higher requirements on the performance of the server, in order to ensure the power supply stability during the operation of the server, the peripheral power supply of a central processing unit (Central Processing Unit, CPU for short) has higher requirements, and if any group of VR power supply stability on a main board is abnormal, the server may be halted, failed or restarted. Therefore, in the server development process, it is necessary to test the stability of VR power supply in various limit use scenarios of the CPU.
Currently, when testing the stability of a VR powered by a server CPU, the stability of the VR powered is usually tested according to a Current Limit (Current Limit) function of the VR. The Current Limit function refers to the maximum Current value supplied to the CPU. However, when VR that does not have the Current Limit function is tested using the Current Limit test condition, since the Current Limit test condition has a small Limit Current, voltage stability between the Limit Current corresponding to the Current Limit test condition and the CPU maximum required Current cannot be tested. For example, if the Current Limit condition is 200 amperes (a) and the CPU maximum Current demand is 500A, the voltage stability between 200A and 500A cannot be tested when the Current Limit condition is used for testing, and thus the overall stability of VR power supply cannot be determined.
In order to realize testing of VR power supply stability with and without Current Limit function under various CPU Limit use scenes, the embodiment of the application provides a method for testing VR power supply stability of CPU, which comprises the steps of judging whether VR has Current Limit function or not before testing VR power supply stability, and selecting a corresponding test script to test according to a judging result to determine the VR power supply stability.
Fig. 1 is a flowchart of a method for testing VR power supply stability of a CPU according to an embodiment of the present application, as shown in fig. 1, where the method includes:
s10: after a test environment is built, running a VR power supply load pulling script to determine whether the current VR has a current limiting function;
s11: if the current VR has the current limiting function, a first test script is run so as to control the GEN5VRTT jig to perform simulation test on the power supply stability of the current VR;
s12: if the current VR does not have the current limiting function, a second test script is run so as to control the GEN5VRTT jig to perform simulation test on the power supply stability of the current VR;
in a specific embodiment, when testing the VR power supply stability of the CPU, firstly, closing the sleep mode of the computer system, determining whether a signal of successful connection of the oscilloscope is obtained, when the connection is successful, setting the coordinate range of the oscilloscope, and if the connection is failed, sending a prompt signal to the terminal. In addition, whether the VR power supply pulling script, the first test script and the second test script exist or not needs to be detected, and if the VR power supply pulling script, the first test script and the second test script do not exist, an installation package corresponding to each test script is obtained for installation.
After a testing environment is built, running a VR power supply pulling load script, and determining whether the Current VR has a Current limiting (Current Limit) function or not through the power supply Current of the pulling load VR. It will be appreciated that when the supply Current of the VR is pulled to the set value of the Current Limit condition, the VR will not provide more Current, and at this time, if the CPU works in a scenario exceeding the Current Limit condition, the excess Current will be provided by the capacitor at the output end, the output capacitor discharges, the output voltage decreases, and the UVP protection is triggered when the output voltage decreases to the set value of the under-voltage protection (Under Voltage Protection, abbreviated as UVP). At this time, it can be determined that the Current VR has the Current Limit function, and then a first test script is run so as to control the GEN5VRTT fixture to perform a simulation test on the power supply stability of the Current VR.
In addition, if the Current VR has a Current Limit function, the VR will always supply Current, and eventually trigger an over-Current protection (Over Current Protection, abbreviated as OCP) protection. Therefore, when determining whether the Current VR has the Current Limit function, whether the Current VR power supply triggers overcurrent protection can be judged, and if the Current VR power supply triggers overcurrent protection, a second test script is run so as to control the GEN5VRTT fixture to perform simulation test on the power supply stability of the Current VR.
When testing the VR power supply stability of the CPU according to the Intel requirement, when the VR does not have the Current Limit function, the Limit condition of the VR power supply needs to be determined according to the maximum power consumption of the CPU, that is, the maximum required Current of the CPU needs to be tested, wherein the Limit Current corresponding to the Current Limit test condition is smaller than the maximum required Current of the CPU. Therefore, VR has a Current Limit function and does not have a test script used by the Current Limit, and when having the Current Limit function, VR performs a test according to a Current Limit corresponding to the Current Limit test condition, that is, calls the first test script to perform the test. And when the Current Limit function is not provided, testing according to the maximum Current required by the CPU, namely, calling a second test script to perform testing.
S13: and acquiring a simulation test result grabbed by the oscilloscope to determine the power supply stability of the current VR.
After the power supply stability of the current VR is subjected to simulation test through the GEN5VRTT jig, the GEN5VRTT jig transmits a simulation test result to the oscilloscope, and the simulation test result grasped by the oscilloscope is obtained to determine the power supply stability of the current VR.
Specifically, according to the coordinate range of the oscilloscope, whether the current peak value exceeds the preset range in the preset period is determined, if so, the current VR is determined to be unstable in power supply, and a prompt signal is sent to the client.
The method for testing the VR power supply stability of the CPU, provided by the embodiment of the application, comprises the following steps: after a test environment is built, running a VR power supply pulling and loading script to determine whether the current VR has a current limiting function, if the current VR has the current limiting function, running a first test script to control a GEN5VRTT tool to perform simulation test on the power supply stability of the current VR, if the current VR does not have the current limiting function, running a second test script to control the GEN5VRTT tool to perform simulation test on the power supply stability of the current VR, and obtaining a simulation test result grabbed by an oscilloscope to determine the power supply stability of the current VR. Therefore, the technical scheme provided by the application judges whether the VR to be tested currently has the current limiting function or not before carrying out the power supply stability test of the VR, selects the corresponding test script for carrying out the stability simulation test for the VR to be tested currently, and avoids adopting the current limiting condition for testing when the VR does not have the current limiting function, namely selecting the script corresponding to the current limiting function for testing, so that the overall power supply stability of the VR cannot be determined, and further the reliability of the server is improved.
It can be understood that when VR has the Current Limit function, when the Current of the pulling VR reaches the Current Limit condition, VR no longer provides additional Current, and at this time, the output voltage is reduced when the capacitor of the output port discharges and the output voltage is reduced to the set value corresponding to the UVP protection, and the UVP protection is triggered. When the VR does not have the Current Limit function, the VR will always supply Current until OCP protection is triggered.
Therefore, when judging whether the Current VR has the Current Limit function, the Current load pulling script can be judged whether to trigger UVP protection when running VR power supply, namely whether the Current VR power supply triggers over-Current protection, if the Current VR power supply triggers UVP protection, the Current VR is determined not to have the Current limiting function, and if the Current VR triggers under-voltage protection, the Current VR is determined to have the Current limiting function.
According to the testing method for the VR power supply stability of the CPU, before the VR power supply stability is tested, whether the current VR has a current limiting function or not is judged by running the VR power supply load pulling script, the corresponding testing script is selected according to the judging result to test the power supply stability, and when the current VR does not have the current limiting function, the current limiting condition is adopted for testing, so that the overall stability of the current VR cannot be determined, and therefore the power supply performance of a server is improved.
In specific implementation, after a simulation test result grabbed by the oscilloscope is obtained, the power supply stability of VR is analyzed. Specifically, whether the current peak value exceeds a preset range in a preset period is judged, if so, the current VR is determined to be unstable, otherwise, the current VR is determined to be stable.
Of course, in order to further improve the accuracy of judgment, whether the current peak value exceeds the preset range or not can be determined to be stable according to whether the number of the current peak value exceeds the preset range in a plurality of preset periods, and of course, when the number exceeds the preset number, the current peak value is determined to be unstable.
In addition, the current fluctuation condition can be checked according to a current waveform diagram grabbed by the oscilloscope, and when the fluctuation frequency of the waveform diagram is greater than the preset frequency, the current VR is determined to be unstable in power supply. And when the power supply is determined to be unstable, transmitting a prompt signal to the terminal so as to remind maintenance personnel.
It should be noted that, the present application is not limited to a specific manner of determining whether the current VR is stable.
According to the method for testing the VR power supply stability of the CPU, when the power supply stability of the current VR is determined, whether the current peak value exceeds the preset range in the preset period is judged, if the current peak value exceeds the preset range, the instability of the power supply of the current VR is determined, a prompt signal is sent, and if the current peak value does not exceed the preset range, the stability of the power supply of the current VR is determined. Therefore, the current VR power supply stability is determined according to the simulation result, the power supply stability of the server is guaranteed, and the reliability of the server is further improved.
Before testing the VR power supply stability of the CPU, detecting whether a VR power supply pulling script, a first test script or a second test script exists, and if not, automatically acquiring an installation package corresponding to each script for installation. Meanwhile, judging whether the connection of the oscilloscopes is successful or not, namely judging whether signals of the connection of the oscilloscopes is successful or not, and if the connection fails, sending prompt signals to the terminal so as to facilitate maintenance personnel.
Of course, if the oscilloscope is successfully connected, a coordinate measuring range of the oscilloscope is set, wherein the coordinate measuring range comprises the amplitude of the ordinate and the time of the abscissa. After the preparation, before running the VR power supply pulling script, in order to avoid that the computer system performs a sleep mode in the test process to cause test failure, the sleep mode of the computer system is closed.
According to the testing method for the VR power supply stability of the CPU, after a testing environment is built, before the VR power supply pulling and loading script is operated to determine whether the current VR has a current limiting function, if the fact that the VR power supply pulling and loading script, the first testing script or the second testing script does not exist is detected, the script corresponding to the installation package is obtained for installation. In addition, whether a signal of successful connection of the oscilloscopes is acquired or not is determined, if the signal is acquired, a coordinate range of the oscilloscopes is set, and if the signal is not acquired, a prompt signal is sent to the terminal. And shutting down a sleep mode of the computer system before running the VR powered pull script. Therefore, the automatic configuration testing environment is realized, the smooth test is ensured, and the power supply stability of the server is further ensured.

In implementation, the GEN5VRTT jig 2 is mounted on a motherboard, one end of the jig is connected with the upper computer 1, a GEN5 operation interface is opened on the upper computer 1, and the oscilloscope 3 is connected by using a GPIB line. And inputting a test instruction into the GEN5 operation interface so as to start the test of the VR power supply stability of the CPU. During testing, the VR power supply load script, the first test script and the second test script are operated on VRTT software so as to control the GEN5VRTT jig 2 to simulate an electronic load, namely, the current of the VR power supply is simulated, the voltage fluctuation reflects the voltage condition, and further, the power supply stability of the VR is checked.
Further, through a GEN5 operation interface, a Sheet to be tested is selected, a sweep frequency result report is read, parameters such as test conditions, frequency points, voltage values and the like are obtained, and test data and waveforms are automatically uploaded to a terminal for a user to check.
