Problems solved by technology
At present, the main solution for testing the USB3.0 interface signal of the server is to modify the register of the USB controller to make the USB controller send out the required code pattern, but the test of the USB3.0 interface signal needs to test a variety of code patterns, which requires frequent reading and writing. Registers, and there are many types of USB3.0 controllers, and the register addresses of each controller are different. It is necessary to change the value of the register according to the data sheet of each controller, and the operation is cumbersome.

The invention discloses a USB3.0 interface signal test system, and the system comprises a signal generation device, a test fixture, a monitoring device, a USB3.0 controller and a USB3.0 controller; the USB3.0 controller and the USB3.0 controller are arranged in equipment to be tested, and the USB3.0 controller is used for switching a test code pattern according to a received Ping.LFPS signal whenentering a test mode; and the monitoring device is used for acquiring test data corresponding to the test code pattern. According to the invention, the Ping.LFPS signal can be output to a device to betested through the signal generation device; therefore, the USB3.0 controller on the equipment to be tested is switched to the corresponding test code pattern; and the monitoring device is used for capturing the test data corresponding to the test code pattern and analyzing the test data, so complicated operations such as changing a register of the USB3.0 controller are avoided, the USB3.0 interface signal test can be completed simply and quickly, and the test efficiency is improved. The invention further discloses a USB3.0 interface signal testing method which has the above beneficial effects.
Description
technical field [0001] The present application relates to the server field, in particular to a USB3.0 interface signal testing system and method. Background technique [0002] At present, the country pays more and more attention to the development of domestic CPU (Central Processing Unit, central processing unit), so the full coverage test of various interface signals of servers and PC platforms equipped with domestic CPU is becoming more and more important. Among them, the USB3.0 interface is a fast, two-way, synchronous transmission, cheap, and hot-swappable serial interface. The USB3.0 interface is easy to use and can connect multiple different devices. As the most common interface, it has many advantages such as convenient use, fast speed, independent power supply, flexible connection, and low cost, so it is widely used in servers, PCs and other equipment. . At present, the main solution for testing the USB3.0 interface signal of the server is to modify the register of...
