Hardware debugging method of PCB

Abstract

The invention provides a hardware debugging method of a PCB, which comprises the steps of S1, carrying out a power supply test on the PCB, if the PCB passes the power supply test, executing the step S2, and if the PCB does not pass the power supply test, executing the step S5; S2, carrying out a DDR test on the PCB, if the PCB passes the DDR test, executing the step S3, and if the PCB does not pass the DDR test, executing the step S5; S3, carrying out a sensitive signal test on the PCB, if the PCB passes the sensitive signal test, executing the step S4, and if the PCB does not pass the sensitive signal test, executing the step S5; S4, performing a signal integrity test on the PCB, and if the PCB passes the signal integrity test, executing the step S5; and S5, ending the test, and generating a test result. According to the hardware debugging method of the PCB, the hardware problem of the PCB can be eliminated at a time.

Description

technical field [0001] The invention relates to the technical field of PCB board hardware debugging, in particular to a method for hardware debugging of a PCB board. Background technique [0002] With the development of technology, electronic products such as smart TVs, set-top boxes, and smart speakers have more and more functions, and the systems are becoming more and more complex, which leads to the CPU, GPU, and DDR of electronic products such as smart TVs, set-top boxes, and smart speakers. The frequency is getting higher and higher, which leads to more and more components on the circuit board (PCB board); the design performance of the PCB board plays a decisive role in the system; but at present, there is no systematic and automated PCB board hardware inspection and debugging method in the industry , the existing PCB board hardware inspection and debugging can only be carried out by experience, and it is impossible to detect all the problems existing in the PCB board h...

[0002] With the development of technology, electronic products such as smart TVs, set-top boxes, and smart speakers have more and more functions, and the systems are becoming more and more complex, which leads to the CPU, GPU, and DDR of electronic products such as smart TVs, set-top boxes, and smart speakers. The frequency is getting higher and higher, which leads to more and more components on the circuit board (PCB board); the design performance of the PCB board plays a decisive role in the system; but at present, there is no systematic and automated PCB board hardware inspection and debugging method in the industry , the existing PCB board hardware inspection and debugging can only rely on experience, and cannot fully detect the problems existing in the PCB board hardware, thereby reducing the stability of the system
