Abstract

The invention relates to a communication module interface test method and device, computer equipment and a storage medium. The method is applied to a communication module with an expansion bus standard PCIE interface of a high-speed serial computer. The method comprises the following steps: receiving a loopback test instruction; entering a host mode in response to the loopback test instruction, and configuring signal resources; entering a loop-back test mode after the host mode is initialized; sending the signal resources to a physical link of a PCIE interface; receiving a retraining result which is returned by the physical link and is used for retraining the differential signal in the signal resources; wherein the physical link used for transmitting the differential signal is short-circuited by a clamp; and determining a test result of the PCIE interface on the communication module according to the retraining result. By adopting the method, the test efficiency can be improved.

Description

technical field [0001] The present application relates to the fields of computer technology and communication technology, in particular to a communication module interface testing method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of science and technology, especially with the popularization of 5G communication technology, the demand for the speed of big data transmission in the network is getting higher and higher. The PCIE (peripheral component interconnect express, high-speed serial computer expansion bus standard) interface can realize high-speed data transmission. Therefore, many wireless communication modules use the PCIE interface to realize high-speed communication. Testing the PCIE interface of the wireless communication module to ensure the integrity and validity of the physical signal transmitted by the PCIE interface is an important test link of the wireless communication module. [0003] In the tradit...
