In view of the above object, a first aspect of the embodiments of the present invention provides an embodiment of a power supply voltage adjustment method. Fig. 1 is a schematic diagram illustrating an embodiment of a power supply voltage adjustment method according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
step S10, reading a current use condition table corresponding to a mainboard where the memory device is located, and judging whether a plurality of electrical appliances arranged on the mainboard need specific voltage required by the memory device based on the current use condition table;
step S20, responding to the specific voltage required by a plurality of electric appliances, respectively acquiring differential voltage signals of the internal memory device and the plurality of electric appliances by using an oscilloscope in the process that the plurality of electric appliances and the internal memory device operate on the basis of the specific voltage provided by a power supply, capturing a first lowest differential voltage value on the differential voltage signal of the internal memory device, and capturing a second lowest differential voltage value on the differential voltage signal of the plurality of electric appliances;

In this embodiment, the standard voltage and current provided by the manufacturer when the electrical appliance is used are recorded on the current use condition table.
In the embodiment of the invention, in the process that a plurality of electric appliances and a plurality of electric appliances operate based on the specific voltage provided by the power supply, the oscilloscope is utilized to respectively obtain the differential voltage signals of the electric appliances and the plurality of electric appliances, the oscilloscope captures the first lowest differential voltage value on the differential voltage signal of the electric appliances, and respectively captures the second lowest differential voltage value on the differential voltage signals of the plurality of electric appliances, if the first lowest differential voltage value is smaller than the first lowest limit value and the second lowest differential voltage value is smaller than the second lowest limit value, the voltage provided by the power supply is adjusted to ensure that the first lowest differential voltage value is positioned in the first error range and the second lowest differential voltage value is positioned in the second error range, thereby avoiding the problem that insufficient voltage is possibly generated when the electric appliances and the plurality of electric appliances operate based on the power supply of the specific voltage, being beneficial to the stable operation of the electric appliances, meanwhile, the operation stability of the electrical appliances is ensured, and the performance of the mainboard is further improved.
In some embodiments, adjusting the voltage provided by the power supply to bring the first lowest differential voltage value within a first error range and the second lowest differential voltage value within a second error range comprises: the control power supply provides a voltage higher than a specific voltage, so that the first lowest differential voltage value is within a first error range, and the second lowest differential voltage value is within a second error range.
In some embodiments, the method further comprises: the plurality of electrical consumers and the memory device are operated based on the adjusted voltage.
In the above embodiment, when the specific voltage initially provided by the power supply is supplied to the memory device and the plurality of electrical consumers, the voltage provided by the power supply needs to be increased because the circuit path loses voltage. Assuming the increased voltage as a new voltage, in the process that a plurality of electric appliances and a plurality of internal memory devices operate based on the new voltage provided by a power supply, respectively acquiring differential voltage signals of the internal memory devices and the plurality of electric appliances by using an oscilloscope, capturing new lowest differential voltage values of the internal memory devices on the differential voltage signals of the internal memory devices, and capturing corresponding new lowest differential voltage values on the differential voltage signals of the plurality of electric appliances; judging whether the new lowest differential voltage value of the memory device is smaller than a first lowest threshold value or not, and judging whether the new lowest differential voltage values of the plurality of electrical appliances are smaller than a second lowest threshold value or not; if the new lowest differential voltage value of the memory device is larger than or equal to the first lowest limit value and falls within the first error range, and the new lowest differential voltage values of the plurality of electrical appliances are larger than or equal to the second lowest limit value and fall within the second error range, the new voltage is used as the voltage used normally, so that the influence caused by the voltage drop of a circuit route is avoided.
In some embodiments, the first minimum threshold is less than the second minimum threshold.
In some embodiments, the plurality of electrical appliances at least include a CPLD, a PCIE device, and a south bridge chip.
In the above example, the voltage tolerance of the memory device is better, and the voltage tolerance of the CPLD, the PCIE device, and the south bridge chip is worse, so the memory device can operate at a lower voltage, and therefore the first minimum limit value is smaller than the second minimum limit value.

3) Testing the constant current: in order to deal with the voltage drop caused by a long-path line, differential lines need to be led out at all positions powered by 3V3, a script captures waveforms through an oscilloscope, when all loads are in operation, an upper computer captures the lowest voltage of each load point through the script, when the memory device is lower than 3V (a first lowest limit value) or other load points are lower than 3.2V (a second lowest limit value), the script enters debugging software to properly adjust the Offset, and when the voltages of the captured points meet the standard, the adjustment is stopped.
4) And testing dynamic current by a script: the requirements of all electrical appliances on dynamic current are different, the requirements on the slope of the dynamic current and the frequency are also different, in order to test the voltage stability of a memory device when 3V3 runs a dynamic load on other electrical appliances, the script automatically adjusts the load of each electrical appliance according to the load condition of each electrical appliance, finally, the voltage condition of 3V3 at the memory device is grabbed through an oscilloscope, the script reads a peak value, when the peak value exceeds 200mV, the script automatically enters a debugging interface, the script automatically adjusts parameters Kp, Kd and Ki, firstly, the script adjusts Kp up and down, then the script reads a voltage value from the oscilloscope, when the peak value is adjusted to be close to 200mV, corresponding up and down adjustment is carried out on Kd and Ki, the voltage value is grabbed through the oscilloscope, and when the peak value is smaller than 200mV, the script stops adjusting.
