Description

Technical Field

[0001] The present invention belongs to the field of automated testing, and in particular, relates to a design method for automatically testing the RGMII eye diagram based on LabVIEW programming. Background Art

[0002] The RGMII eye diagram test is used to verify whether the RGMII bus signal meets the requirements and whether the function works properly. Usually, the settings of the oscilloscope need to be done manually by humans, which is time-consuming, laborious, and inefficient. Therefore, a design method for automatically testing the RGMII eye diagram based on LabVIEW programming is invented. Summary of the Invention

[0003] In view of this, the present invention aims to propose a design method for automatically testing the RGMII eye diagram based on LabVIEW programming, which can be applied to the verification of a variety of different devices to be tested with RGMII buses. To achieve the above object, the technical solution of the present invention is realized as follows:

[0004] A design method for automatically testing the RGMII eye diagram based on LabVIEW programming includes the following steps:

[0005] S1. Power on the prototype to be tested with an RGMII bus, and use high-speed single-ended probes to weld on the CLK and TX signal lines of the RGMII bus respectively;

[0006] S2. Connect the high-speed single-ended probes to the oscilloscope end, set channel 1 of the oscilloscope to the CLK of the RGMII bus, and set channel 2 of the oscilloscope to the TX of the RGMII bus;

[0007] S3. Connect the computer installed with the test program to the oscilloscope through the network port to complete the physical connection of the test scheme;

[0008] S4. Run the written test program to let the test program automatically complete the oscilloscope test of the RGMII eye diagram, complete the determination of the results, and save the data.

[0009] Further, it also includes an oscilloscope parameter setting method: First, set Channel 1 and Channel 2 of the oscilloscope. Among them, Channel 1 is the CLK signal of the RGMII bus, and Channel 2 is the TX signal of the RGMII bus. Automatically set the voltage scale of Channel 1 of the oscilloscope to 150 mV per grid, automatically set the voltage scale of Channel 2 of the oscilloscope to 150 mV per grid, and automatically set the time scale of the oscilloscope to 1 ns per grid. After the setting is completed, automatically perform the GATING function setting for Channels 1 and 2 of the oscilloscope. The GATING function is a region selection function, that is, only the selected region will perform waveform acquisition and analysis. Currently, use the GATING function to select the TX signal of the RGMII waveform in two clock cycles. The automation program reads the GATING function parameters and determines whether the parameters are correct. If correct, proceed; if incorrect, prompt to manually set the GATING function parameters.

[0010] Further, automatically complete the clock recovery parameter setting for Channels 1 and 2 of the oscilloscope. After completing the automatic setting of the GATING function, the program then performs the clock recovery parameter setting. Automatically set Channel 1 as the clock source and Channel 2 as the data source, and the mode is a clock separation structure, so as to automatically generate an eye diagram. The automation program reads the clock recovery parameter settings and determines whether the parameters are correct. If correct, proceed; if incorrect, prompt to manually set the clock recovery parameters.

[0011] Further, automatically complete the placement of the oscilloscope eye diagram template. After completing the setting of the GATING function and the clock recovery parameter setting, the RGMII eye diagram has been formed. At this time, the automation program will load the set RGMII eye diagram template and place it on the oscilloscope display screen. The automation program determines whether the RGMII eye diagram will touch the RGMII eye diagram template. If it does not touch the RGMII eye diagram template, the program prompts that the test result is PASS; if it touches the RGMII eye diagram template, the program prompts that the test result is FAIL.

[0012] In a second aspect, this solution discloses an electronic device, including a processor and a memory communicatively connected to the processor and used to store instructions executable by the processor. The processor is used to execute the design method for automatically testing the RGMII eye diagram based on LabVIEW programming described in the first aspect.

[0013] In a third aspect, this solution discloses a server, including at least one processor and a memory communicatively connected to the processor. The memory stores instructions executable by the at least one processor. The instructions are executed by the processor so that the at least one processor executes the design method for automatically testing the RGMII eye diagram based on LabVIEW programming described in the first aspect.

[0014] In a fourth aspect, the present solution discloses a computer-readable storage medium storing a computer program which, when executed by a processor, implements the design method for automatically testing the RGMII eye diagram based on LabVIEW programming described in the first aspect.

[0024] Step 1: Power on the prototype to be tested with an RGMII bus, and use high-speed single-ended probes to weld them on the CLK and TX signal lines of the RGMII bus respectively;

[0025] Step 2: Connect the high-speed single-ended probes to the oscilloscope end. Set channel 1 of the oscilloscope to the CLK of the RGMII bus, and set channel 2 of the oscilloscope to the TX of the RGMII bus;

[0026] Step 3: Connect the computer installed with the LabVIEW program to the oscilloscope through the network port to complete the physical connection of the test solution;

[0027] Step 4: Run the written LabVIEW program to automatically complete the oscilloscope's test of the RGMII eye diagram, complete the determination of the results, and save the data;

[0028] Automatically complete the oscilloscope parameter settings. After the program starts running, first set channel 1 and channel 2 of the oscilloscope. Among them, channel 1 is the CLK signal of the RGMII bus, and channel 2 is the TX signal of the RGMII bus. Automatically set the voltage scale of channel 1 of the oscilloscope to 150 mV per grid, automatically set the voltage scale of channel 2 of the oscilloscope to 150 mV per grid, and automatically set the time scale of the oscilloscope to 1 ns per grid. After the settings are completed, automatically perform the GATING function settings for channels 1 and 2 of the oscilloscope. The GATING function is an area selection function, that is, only the selected area will perform waveform acquisition and analysis. Currently, the TX signal of the waveforms of two clock cycles of the RGMII is selected using the GATING function. The automation program reads the GATING function parameter settings and judges whether the parameters are correct. If correct, it will execute the following steps; if incorrect, it will prompt to manually set the GATING function parameters.

[0029] Automatically complete the Clock Recovery parameter settings for oscilloscope channels 1 and 2. After completing the automated setting of the GATING function, the program then performs the Clock Recovery parameter settings, automatically setting channel one as the clock source, channel two as the data source, and the mode as a clock separation structure, thus automatically realizing the generation of the eye diagram. The automated program reads the Clock Recovery parameter settings and determines whether the parameters are correct. If correct, it proceeds; if incorrect, it prompts to manually set the Clock Recovery parameters.

[0030] Automatically complete the placement of the oscilloscope eye diagram template. After completing the settings of the GATING function and the Clock Recovery parameters, the RGMII eye diagram is already formed. At this time, the automated program will load the already set RGMII eye diagram template and place it on the oscilloscope display screen. The automated program determines whether the RGMII eye diagram touches the RGMII eye diagram template. If it does not touch the RGMII eye diagram template, the program prompts that the test result is PASS; if it touches the RGMII eye diagram template, the program prompts that the test result is FAIL.

[0031] Compared with the prior art, the beneficial effect of the present invention lies in realizing a design method for automatically testing the RGMII eye diagram based on labview programming, which can automatically control the oscilloscope for parameter settings and achieve automated testing. The present invention can greatly improve the testing efficiency.
