Problems solved by technology

During the production process of the USB Type-C interface, there will be some problems that affect the quality of signal transmission. For example, at the connection between the connector pin and the PCB, the high-speed line signal will be reflected on the connector and the PCB during the transmission process. , affecting the quality of signal transmission and causing signal loss; another example is the phenomenon of over-soldering and under-soldering in the wave soldering process, which makes crosstalk occur during signal transmission
[0005] In the prior art, for the above-mentioned problems in the production process of the USB Type-C interface, there is no detection method that can detect the signal loss and signal crosstalk of the USB Type-C interface

Abstract

The invention discloses a USB interface simulation detection method, comprising: inputting test data to a simulation model, wherein, the simulation model is a model simulating USB interface work, andthe test data is used for simulating input items when the USB interface works; receiving a test result obtained by the simulation model according to the test data; drawing the result curve according to the test result; the parameter characteristics of the simulation model are obtained by the result curve. The parameter characteristics are used to indicate the product quality of the USB interface.The embodiment of the application also provides a USB interface emulation detection device and a storage medium. The application simulates the working condition of the USB interface by constructing asimulation model, and then inputs test data to test the simulation model, so that the relevant parameters of the finished product input of the USB interface can be quickly detected after the production is completed; You can also enter parameters before production to obtain the best production data to guide subsequent production.

Description

technical field [0001] The invention relates to the technical field of simulation detection, in particular to a USB interface simulation detection method, device and storage medium. Background technique [0002] USB 3.1 Gen2 is the latest USB specification, which was initiated by companies such as Intel. The data transmission speed can be increased to a speed of 10Gbps. Compared with USB 3.0 (ie USB 3.1 Gen1) technology, the new USB technology uses a more efficient data encoding system and provides more than double the effective data throughput rate. It is fully backward compatible with existing USB connectors and cables. USB 3.1 Gen2 is compatible with the existing USB 3.0 (ie USB 3.1 Gen1) software stack and device protocol, 5Gbps hubs and devices, and USB 2.0 products. [0003] USB 3.0 is 8b / 10b coded, in each transmission of 10bit data, 2bits exist as a check code, so the bandwidth loss will be as high as 20% (2 / 10). USB 3.1 uses 128b / 132b encoding, only 4 bits are u...
