Abstract

The invention relates to a method for quickly testing a USB-PD module. A main control chip receives an instruction code sent by Python through a serial port; the corresponding instruction code is parsed; if the instruction code is correct, corresponding PD module testing is carried out; if the instruction code is incorrect, a no-response signal is sent to the Python through the serial port; and ifno response signal sent out by the Python is received within a certain period of time, testing exits in a forced manner. The main control chip controls instruction sending and physical layer, protocol layer, and strategy layer function modules of the PD module are tested, wherein the protocol layer has the control information function, the data Information function, and extended information function. With the testing method, the USB-PD module can be tested conveniently, rapidly and flexibly. Automatic recording is carried out and the measurement data are analyzed and stored, so that the tester is assisted in finding out the problem of the model rapidly.

Description

technical field [0001] The invention belongs to the technical field of USB-PD modules, and in particular relates to a method for quickly testing a USB-PD module. Background technique [0002] USB-PD (short for USB Power Delivery) is a power transmission concept proposed after the port of type-c (USB-C for short, which is a hardware interface specification for Universal Serial Bus (USB)) in USB3.1. The charging capacity is expanded to 10 times the current maximum up to 100 watts. [0003] But at present, when measuring the USB-PD (referred to as PD) module, the relevant PD module test can only be carried out according to the instructions of the specification. Because the PD module protocol is relatively complicated, especially if the chip manufacturer wants to obtain the PD2.0 or PD3.0 certification, it must be ensured that when measuring the PD module, all functions of the PD module must be able to quickly traverse and test, and can be flexibly configured by software to cov...
