[0036] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. 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.

[0037] In one embodiment, Figure 1As shown, a power consumption automation test method based on UFS is provided, and the method includes:

[0038] Step 102, connect a programmable high-precision DC power supply to the UFS host, power the VCC / VCCQ / VCCQ2 pins of the UFS, and connect the tester to the UFS host via ADB;

[0039] Step 104, the UFS host establishes communication with the UFS device, uses the DME command defined in the UFSHCI protocol to switch the transmission mode of the M-PHY layer of the UFS device, and uses the SSU command defined in the UFS protocol to switch the power consumption mode of the UFS device;

[0040] Step 106, the test machine sends a current collection instruction to the programmable high-precision DC power supply to obtain the VCC / VCCQ / VCCQ2 current of the UFS at this time to test the static power consumption of the UFS;

[0041] Step 108, in various UFS switching modes, the UFS host issues read and write operations to perform read and write operations on the UFS device, sends current collection instructions to the programmable high-precision DC power supply, and obtains the VCC / VCCQ / VCCQ2 current size of the UFS at this time to test the UFS dynamic power consumption.

[0042] In this embodiment, a power consumption automation test method based on UFS is provided, which can be applied to the power consumption automation test of UFS chips. Specifically, by using a programmable high-precision DC power supply (such as: GW Instek PPH-1503D or others) to connect a UFS host (such as: Android platform), the VCC / VCCQ / VCCQ2 pins of the UFS device module are externally powered, and the power consumption of UFS in various states is automatically measured.

[0043] The UFS host establishes communication with the UFS device, uses the DME command defined by the UFSHCI protocol to switch the transmission mode (HS-Mode, LS-Mode, HIBERN8) of the M-PHY layer of the UFS device and the UFS protocol command SSU to switch the power consumption mode of the device (Active, Idle, PowerDown, Sleep, etc.), and on this basis measures the static power consumption of the UFS, or the UFS host issues read and write operations to read and write UFS in various modes to measure the dynamic power consumption of the UFS. Establish a script program to automatically switch between UFS modes, and automatically collect the current size from the DC power supply. Finally, uniformly collect the current data size of each UFS mode, and perform automatic analysis and comparison with the data of competing products.

[0044] In this embodiment, by connecting a programmable high-precision DC power supply to a UFS host, powering the VCC / VCCQ / VCCQ2 pins of the UFS, and connecting the tester to the UFS host through ADB; the UFS host establishes communication with the UFS device, uses the DME command defined in the UFSHCI protocol to switch the transmission mode of the M-PHY layer of the UFS device, and uses the SSU command defined in the UFS protocol to switch the power consumption mode of the UFS device; the tester sends a current acquisition instruction to the programmable high-precision DC power supply, obtains the VCC / VCCQ / VCCQ2 current of the UFS at this time to test the static power consumption of the UFS; in various switching modes of the UFS, the UFS host sends a read-write operation to read and write the UFS device, sends a current acquisition instruction to the programmable high-precision DC power supply, obtains the VCC / VCCQ / VCCQ2 current of the UFS at this time to test the dynamic power consumption of the UFS. The present invention can realize the fully automated test of the static power consumption and dynamic power consumption of the UFS, greatly improves the test efficiency, and avoids wasting unnecessary manpower costs.

[0045] In one embodiment, the steps of connecting the programmable high-precision DC power supply to the UFS host, powering the VCC / VCCQ / VCCQ2 pins of the UFS, and connecting the test machine to the UFS host via ADB further include:

[0046] The tester sends a command to the programmable high-precision DC power supply, and the programmable high-precision DC power supply supplies power to the VCC / VCCQ / VCCQ2 pins of the UFS with the correct voltage according to the protocol standard, and the UFS host is turned on and started.

[0047] In one embodiment, Figure 2 As shown, a UFS-based power consumption automation test method is provided, which also includes:

[0048] Step 202, using Python to compile a dictionary of UFS mode switching instructions, establish a loop function to enable the UFS host to send a UFS mode switching instruction set, use pyvisa to adjust the voltage and current of the programmable high-precision DC power supply sending instructions, and collect the current from the programmable high-precision DC power supply;

[0049] Step 204 , write the test collected data into a local Excel file for data preservation, and after the UFS static power consumption and dynamic power consumption tests are completed, perform data analysis and comparison on the saved Excel file.

[0050] Specifically, a programmable high-precision DC power supply is used to connect the UFS host, and external power is supplied to the VCC / VCCQ / VCCQ2 pins of the UFS device module. The instructions used by the programmable power supply need to meet the IEEE488.2 and SCPI standards. The Python third-party library pyvisa can be used to adapt the voltage, current range, current limit, etc. of the connected programmable power supply and read the current at the same time.

[0051] After the programmable power supply uses the correct voltage to power VCC / VCCQ / VCCQ2, the UFS host establishes communication with the UFS device, and uses the DME command defined by the UFSHCI protocol to switch the transmission mode (HS-Mode, LS-Mode, HIBERN8) of the M-PHY layer of the UFS device and the UFS protocol command SSU to switch the power consumption mode of the device (Active, Idle, PowerDown, Sleep, etc.). On this basis, the static power consumption of UFS is measured, or in these various modes, the UFS host sends read and write operations to read and write UFS to measure the dynamic power consumption of UFS.

[0052] Use Python to make a dictionary collection of the UFS mode switching instructions, establish a loop function to enable the UFS host to send an instruction set to the UFS device, and reference pyvisa to send instructions to the DC power supply to adapt the voltage, current range, current limit, etc., and then automatically collect the current from the DC power supply and write it to the local Excel file for data preservation. After the UFS various transmission mode tests are completed, the saved Excel data is analyzed and compared to realize the UFS power consumption automation test and improve the test efficiency.

[0053] In this embodiment, if Figure 3 As shown, a power consumption automation test method based on UFS is provided, and the specific implementation steps are as follows:

[0054] Step 1: Use a programmable high-precision DC power supply that meets the IEEE488.2 and SCPI standards to connect the UFS host and externally power the VCC / VCCQ / VCCQ2 pins of the UFS device module.

[0055] Step 2: The test computer sends instructions to the connected programmable power supply through the Python third-party library pyvisa to supply power to the UFS device module VCC / VCCQ / VCCQ2 pins with the correct voltage (according to the UFS3.1 protocol VCC 2.4~3.6V, VCCQ1.14~1.95V), and the UFS host starts normally.

[0056] Step 3: The test computer connects to the UFS host through ADB, and the UFS host drives the communication. The DME command defined by the UFSHCI protocol is used to switch the transmission mode (HS-Mode, LS-Mode, HIBERN8) of the M-PHY layer of the UFS device.

[0057] Step 4. The test computer connects to the UFS host through ADB. The UFS host drives the communication. The UFS protocol is used to command the SSU to switch the power consumption mode of the UFS device (Active, Idle, PowerDown, Sleep, etc.). The Python third-party library pyvisa (or other program methods) is used to send a current collection instruction to the connected programmable power supply to obtain the VCC / VCCQ / VCCQ2 current size of the UFS at this time (i.e., static power consumption).

[0058] Step 5. In various switching modes of steps 3 and 4 of UFS, the UFS host drives communication and issues read and write operations to read and write the UFS device. The Python third-party library pyvisa (or other program methods) is used to send current collection instructions to the connected programmable power supply to obtain the current size (i.e. dynamic power consumption) of VCC / VCCQ / VCCQ2 of the UFS at this time.

[0059] Step 6: Save the collected current data to the test computer, use algorithms such as root mean square to process the current data, draw data, compare competing products, etc.

[0060] Specifically, the Flow of different test tasks is as follows:

[0061] Each test mode will go through the following steps: hw reset, release unit attension, speed cut, SSU, synchronously adjust the programmable power supply current range, and then capture the power consumption.

[0062] H8 low power consumption test: hw reset-->release unit attension-->power mode speed cut (PWM / HS / LANE1 / LANE2, etc.)-->SSU (active / powerdown / sleep / deepsleep)-->H8-->idle3s-->programmed power supply grabs current for about 20s-->exit H8;

[0063] Static power consumption test: hw reset-->release unit attension-->power mode speed cut (PWM / HS / LANE1 / LANE2, etc.)-->SSU (active / powerdown / sleep / deepsleep)-->idle3s-->programmed power supply grabs current for about 20s;

[0064] Dynamic power consumption test: hw reset-->release unit attension-->power mode speed cut (PWM / HS / LANE1 / LANE2, etc.)-->SSU (active)-->issue read / write instructions-->use synchronous thread to program the power supply to capture current.

[0065] It should be understood that although Figure 1-Figure 3 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1-Figure 3 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.
