Embodiment 1

[0024] Such as figure 1 As shown, it is a schematic diagram of the software framework of the handheld USB3.0 protocol analyzer of the present invention, including: data capture, filter and trigger module 101, protocol analysis module 102, protocol simulation module 103, statistics module 104, control module 105 and human machine interface module 106; wherein,

[0025] The data capturing, filtering and triggering module 101 includes a data capturing submodule, a data filtering submodule and a data triggering submodule;

[0026] The data capture sub-module is used to store the data packets sent during the USB3.0 master-slave device link establishment and data transmission process according to the order of capture time, and send the captured data packets to the protocol analysis module for analysis;

[0027] The data filtering submodule is used to control and capture specific types of data packets;

[0028] The data triggering submodule is used to start storing the captured dat...

Abstract

The present invention relates to the technical field of testing, in particular to a hand-held USB3.0 protocol analyzer, which is characterized in that it comprises: a data capture, filtering and triggering module, a protocol analysis module, a protocol simulation module, a statistical module, a control module and a man-machine Interface module; the software of the handheld USB3.0 protocol analyzer of the present invention adopts a hierarchical design, and is divided into a hardware control layer, a driver layer and an application layer; the hardware adopts a highly integrated design method, which overcomes the ease of use of existing test instruments Problems such as poor performance, non-portability and high price make the handheld USB3.0 protocol analyzer of the present invention not only meet the requirements of USB3.0 protocol analysis and USB3.0 protocol simulation test, but also be easy to use and easy to carry.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a hand-held USB3.0 protocol analyzer. Background technique [0002] As USB3.0 technology is more and more widely used, there are more and more personal computers, consumer and mobile products with USB3.0 interface. With the increasingly wide application range of USB3.0 master-slave device terminals, there are few easy-to-use automatic test instruments for USB3.0 device terminals, which leads to the consumption of a large amount of USB3.0 device terminal detection in mass production. In addition, in the development process of USB3.0 interface, convenient and practical USB3.0 protocol analysis equipment is needed. However, the current USB3.0 protocol analyzers on the market generally adopt the independent design of the protocol generator and the analyzer, and both need to be tested through the control of an external computer. Expensive, the generator needs complex data programmin...
