The method for displaying the signal state information provided by the embodiment of the application is described in detail below through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for displaying signal status information according to an embodiment of the present application, where, as shown in fig. 1, the method may include:
step 101, acquiring signal values corresponding to each preset phase in output signals output by pins of a physical interface according to preset acquisition times, and obtaining a plurality of signal values corresponding to each preset phase.
Wherein, the pins are in one-to-one correspondence with data bits in preset signal data; the output signal is a signal output by the pin according to the value of the corresponding data bit.
In the embodiment of the application, the signal value corresponding to each preset phase is acquired in the output signals output by the pins of the physical interface according to the preset acquisition times to obtain a plurality of signal values corresponding to each preset phase, and then the number of signal values of the signal values which are the same as the preset standard value in the plurality of signal values corresponding to each preset phase is obtained.
It should be noted that, the preset collection times are times for collecting signal values when signals of the pins are in preset phases, for example, the preset collection times may be 8 times, 20 times, 30 times, etc., and the more the preset collection times, the higher the reliability of the displayed signal state information. The preset collection times are equal to the number of signal values corresponding to each preset phase of one pin.
The physical interface may be a high-speed interface such as Thunderbolt (Thunderbolt) 4, universal serial bus (USB, universal Serial Bus) 4.0, thunderbolt 3, USB 3.0, high-speed serial computer expansion bus standard (PCI Express, peripheral component interconnect Express) 4.0, PCI Express 3.0, serial hard disk interface (SATA, serial Advanced Technology Attachment) 3.0, displayPort 1.4, high-definition multimedia interface (HDMI, high Definition Multimedia Interface) 2.1, double data rate tri-synchronous dynamic random access memory (DDR 3, double-data-rate three synchronous dynamic random access memory) interface, double data rate tetra-synchronous dynamic random access memory (DDR 4, double-data-rate four synchronous dynamic random access memory) interface, double-data rate five-synchronous dynamic random access memory (DDR 5, double-data-rate five synchronous dynamic random access memory) interface, double-data rate six-synchronous dynamic random access memory (DDR 6, double-data-rate six synchronous dynamic random access memory) interface, and the like. The port physical layer (PHY) of the physical interface has a calibration module, which is configured to calibrate signals of each pin of the physical interface, so as to ensure correctness of signals of each pin and improve signal quality.
The physical interface includes a plurality of pins, for example, the DDR4 interface has 8 pins.
The preset phases are phase points for collecting signal values of the signals, the number of the preset phases is a plurality, for example, the number of the preset phases can be 256, the preset phases can comprise 0 degree, 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, … …,255 degrees and the like, and the signal values can be collected from small to large according to the magnitude of the preset phases.

Wherein the number of signal values and the stability of the output signal are in a positive correlation or a negative correlation.
In the embodiment of the application, the number of signal values of the signal values identical to the preset standard value in the plurality of signal values corresponding to each preset phase is obtained, and then the number of signal values is used as the signal state information of the output signal to be displayed.
It should be noted that, the preset standard value may be a binary number "1" or a binary number "0", the value of the data bit in the signal data is in a binary form, and the signal value is in a binary form. When the preset standard value is the same as the value of the data bit in the signal data corresponding to the signal value (for example, the preset standard value is binary number "1", and the value of the data bit is binary number "1"), the more the number of signal values is, the more the time when the signal value is the same as the value of the data bit in the corresponding signal data is, that is, the more the time when the signal value of the output signal output by the pin corresponding to the number of signal values is correct is, the better the stability of the output signal is; when the values of the data bits in the signal data corresponding to the preset standard value and the signal value are different (for example, the preset standard value is a binary number of "1", and the value of the data bits is a binary number of "0"), the larger the number of signal values is, the smaller the time when the signal value is the same as the value of the data bits in the corresponding signal data is, that is, the smaller the time when the signal value of the output signal output by the pin corresponding to the number of signal values is correct is, and the worse the stability of the output signal is.
And step 103, displaying the signal value quantity as the signal state information of the output signal.
In the embodiment of the application, the signal value quantity is used as the signal state information of the output signal to be displayed, so that a worker can analyze the signal quality after the physical interface is calibrated.
It should be noted that the display mode may be in the form of an image, a table, or the like.
For example, the number of preset collection times is 8, the number of pins of the physical interface is 8, the pins are respectively pin 1, pin 2, pin 3, pin 4, pin 5, pin 6, pin 7 and pin 8, the number of preset phases is 256, the preset phases are sequentially 0 degree, 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, … … and 255 degrees from small to large, the output signals output by pin 1 are collected for 8 times at the signal value of 0 degree, and the collected signal values are respectively: 1. 1, 1 1, the preset standard value is set to be 1, the number of the signal values is 8 as the acquired signal values are the same as the preset standard value; the output signal output by the pin 1 is collected for 8 times at a signal value with the phase of 1 degree, and the collected signal values are respectively as follows: 1. 1, 0, 1, the preset standard value is 1, and the number of the signal values is 7 because one signal value in the acquired signal values is different from the preset standard value; the output signal output by the pin 1 is collected for 8 times at a signal value with the phase of 2 degrees, and the collected signal values are respectively as follows: 1. 0, 1, 0, and the preset standard value is 1, and since two signal values in the collected signal values are different from the preset standard value, the number of signal values is 6 … …, and so on, until the number of signal values of all preset phases (256 preset phases in total) corresponding to the pin 1 is obtained. And then respectively acquiring the signal value numbers of all preset phases corresponding to the pin 2, the pin 3, the pin 4, the pin 5, the pin 6, the pin 7 and the pin 8, which are not repeated here, and finally displaying all the signal value numbers.
In summary, in the embodiment of the present application, firstly, the signal value corresponding to each preset phase in the output signal output by the pin of the physical interface is collected according to the preset collection times, so as to obtain a plurality of signal values corresponding to each preset phase, where the pin corresponds to the data bit in the preset signal data one by one, the output signal is a signal output by the pin according to the value of the corresponding data bit, then the number of signal values of the signal values corresponding to each preset phase, which is the same as the preset standard value, is obtained, and then the number of signal values is used as the signal state information of the output signal.
Fig. 2 is a flowchart of specific steps of a method for displaying signal status information according to an embodiment of the present application, as shown in fig. 2, the method may include:
Step 201, collecting signal values corresponding to each preset phase in output signals output by pins of a physical interface according to preset collection times, and obtaining a plurality of signal values corresponding to each preset phase.
Wherein, the pins are in one-to-one correspondence with data bits in preset signal data; the output signal is a signal output by the pin according to the value of the corresponding data bit.
The implementation of this step is similar to the implementation of step 101, and will not be described here again.
Optionally, in some embodiments, the signal data is in the form of binary data, and adjacent data bits in the signal data have opposite values.
In the embodiment of the application, because the preset signal data is binary, values of adjacent data bits in the signal data are opposite, so that signal values of signals output by two adjacent pins of the physical interface are opposite, points corresponding to all signal values of output signals are sequentially connected in a coordinate system which is displayed by taking a preset phase as an abscissa axis and the number of the signal values as an ordinate axis, after a change curve corresponding to the output signals in the coordinate system is formed, the change curves corresponding to the two adjacent pins of the physical interface form a closed area, and all the closed areas can form an overlapping area. The closer the stability of the signals output by all pins is, the better the signal quality is, and the closer the stability of the signals output by all pins is, the closer the corresponding change curves of all pins are, and the larger the overlapping area is. Therefore, the staff can judge the signal quality according to the size of the overlapping area, namely, the larger the overlapping area is, the better the signal quality is.
It should be noted that, when the signal data is read, the values of the data bits in the signal data are alternately changed according to the time sequence, that is, when the signal data is read, the values of the data bits read at adjacent reading moments are opposite, for example, when the signal data is read, the value of the data bit read at the first reading moment is binary "1", the value of the data bit read at the second reading moment is binary "0", the value of the data bit read at the third reading moment is binary "1", the value of the data bit read at the fourth reading moment is binary "0", … …, and so on, so that the output signal of the pin is represented as a square wave according to the time sequence.
Step 202, obtaining the number of signal values of the signal values identical to the preset standard value from the plurality of signal values corresponding to each preset phase.
Wherein the number of signal values and the stability of the output signal are in a positive correlation or a negative correlation.
The implementation of this step is similar to the implementation of step 102 described above, and will not be described here again.
And 203, displaying the corresponding relation among the pin, the output signal, the preset phase and the signal value number as the signal state information.
Optionally, in some embodiments, after step 201, the method further comprises the following steps (step 204 to step 205):
Step 204, determining a display signal value corresponding to each preset phase according to a plurality of signal values corresponding to each preset phase.
In the embodiment of the application, the display signal value corresponding to each preset phase is determined according to the plurality of signal values corresponding to each preset phase, and then the corresponding relation among the pin, the output signal, the preset phase and the display signal value is displayed as the signal state information.
Optionally, in some embodiments, step 204 includes the following sub-steps (sub-step 2041, sub-step 2042):
in the substep 2041, in the case that all the signal values corresponding to the preset phase are the same value, determining that the display signal value corresponding to the preset phase is the same value.
In the embodiment of the application, under the condition that all signal values corresponding to the preset phase are the same value, the display signal values corresponding to the preset phase are determined to be the same value, so that the signal state information of the output signal of the display pin in the preset phase is realized.
It should be noted that, all signal values corresponding to the preset phase are the same value, so that the stability of the output signal of the pin in the signal of the preset phase is good, and at the moment, the signal quality is known to the staff by showing that the signal values corresponding to the preset phase are the same value, namely, the stability of the output signal of the pin in the signal value of the preset phase is good.
For example, if all signal values corresponding to the preset phase are binary "1", the display signal value corresponding to the preset phase is "1".
In the substep 2042, in all signal values corresponding to the preset phase, if there is a signal value different from the other signal values, the display signal value corresponding to the preset phase is set to a preset value.
In the embodiment of the application, the display signal value corresponding to the preset phase is set as the preset value under the condition that the signal value different from other signal values exists in all the signal values corresponding to the preset phase, so that the signal state information of the output signal of the display pin in the preset phase is realized.
It should be noted that the preset value may be 1/2. And in all signal values corresponding to the preset phase, signal values different from other signal values exist, and the fact that the stability of the output signal of the pin in the signal of the preset phase is poor is indicated, at the moment, the signal value corresponding to the preset phase is in a metastable state by showing that the signal value corresponding to the preset phase is a preset value, so that a worker can know the signal quality, namely, the stability of the output signal of the pin in the signal value of the preset phase is poor.
For example, in all signal values corresponding to the preset phase, one signal value is binary "0", and the other signal values are binary "1", and then the display signal value corresponding to the preset phase is 1/2.
By performing sub-steps 2041 to 2042, it is possible to determine a presentation signal value corresponding to each preset phase from a plurality of signal values corresponding to each preset phase.
And 205, displaying the corresponding relation among the pin, the output signal, the preset phase and the display signal value as the signal state information.
In the embodiment of the application, the corresponding relation among the pin, the output signal, the preset phase and the display signal value is used as the signal state information to display, so that a worker can know the signal quality of the output signal of the pin in the preset phase.
Optionally, in some embodiments, in the displayed coordinate system with the preset phase as the abscissa axis and the display signal value as the ordinate axis, points corresponding to all display signal values of the output signal are determined, and the points corresponding to all display signal values of the output signal are sequentially connected to form a change curve corresponding to the output signal in the coordinate system, where the change curve is a curve in which the display signal value changes along with the preset phase. For example, fig. 4 is a graph of a variation of a display signal value of one pin along with a preset phase, the display signal value corresponding to the X1 point is "1", the display signal value corresponding to the X2 point is a preset value 1/2, and the display signal value corresponding to the X3 point is "0".
The steps 204 to 205 may be implemented to display a signal value of the output signal of the pin in the signal of the preset phase, so that a worker can know the signal quality of the output signal of the pin in the preset phase, that is, the stability of the output signal.

Step 207, after each reading of the signal data, controlling the corresponding pins to output the corresponding output signals according to the values of the data bits in the signal data.
In the embodiment of the application, the corresponding pins are controlled to output the corresponding output signals according to the values of the data bits in the signal data after the signal data are read each time, and then the signal values corresponding to each preset phase in the output signals are acquired according to the preset acquisition times after the signal data are read each time to obtain a plurality of signal values corresponding to each preset phase.

By setting the data bit values of the signal data read in adjacent times to opposite values, the display signal values in the same preset phase in the adjacent signal test of one pin are opposite, and further the change curves in the adjacent signal test of one pin form closed areas, and all the closed areas can form overlapping areas. The closer the stability of the output signal of one pin in all signal tests, the better the signal quality, and the closer the stability of the output signal of one pin in all signal tests, the closer the variation curve of one pin in all signal tests, the larger the overlap area.

In the embodiment of the application, the points corresponding to the number of all signal values of the output signal are determined in the displayed coordinate system taking the preset phase as the abscissa axis and the number of signal values as the ordinate axis, so that all the points corresponding to the output signal are sequentially connected to form the change curve corresponding to the output signal in the coordinate system.
Step 209, sequentially connecting all points corresponding to the output signals to form a change curve corresponding to the output signals in the coordinate system.
The change curve is a curve of the signal value quantity changing along with the preset phase.
In the embodiment of the application, because the preset signal data is binary, the values of adjacent data bits in the signal data are opposite, so that the signal values of signals output by two adjacent pins of the physical interface are opposite, a change curve corresponding to the output signal in a coordinate system is formed by sequentially connecting all points corresponding to the output signal, a closed area is formed by the change curves corresponding to the two adjacent pins of the physical interface, and an overlapping area can be formed by all the closed areas. The closer the stability of the signals output by all pins is, the better the signal quality is, and the closer the stability of the signals output by two pins is, the closer the corresponding change curves of all pins are, and the larger the overlapping area is. Therefore, the staff can judge the signal quality according to the size of the overlapping area, namely, the larger the overlapping area is, the better the signal quality is.
