Multi-interface test system and method

Abstract

The invention discloses a multi-interface test system and method. The test system comprises upper computer testing software and an FPGA chip, the FPGA chip comprises a PCIE module, a plurality of serial port modules, an IO interface module and a testing module, wherein the IO interface module comprises a plurality of IO interfaces, the upper computer testing software is in communication connection with the PCIE module, and the PCIE module is connected with the serial port modules and the IO interface module. When a serial port test is carried out, the serial port module is in communication connection with a serial port of a tested computer; when the IO interface is tested, the IO interface is connected with the IO interface of the tested computer; and the testing module is configured to test the interface state of the serial port and / or the IO interface of the tested computer. According to the invention, the test efficiency can be improved, the fault elimination efficiency is improved, and test failure caused by interference data is avoided.

Description

technical field [0001] The invention relates to the technical field of computer testing, in particular to a multi-channel interface testing system and method. Background technique [0002] In the field of industrial control, serial ports and IO (Input / Output, input / output) interfaces are commonly used computer communication interfaces, and the implementation methods include dedicated serial ports, IO chip implementations, and FPGA implementations. FPGA implements serial ports and IO ports in a more flexible way, which is convenient for expansion. To perform a serial port test, it is necessary to connect a serial port of the computer under test to the serial port of the test computer, the computer under test and the test computer send and receive data to each other, and judge whether the serial port is working normally by comparing the received data with the sent data. The IO interface test is similar to the serial port test method, which requires the computer under test and...

Problems solved by technology

[0003] Each serial port and IO interface test needs to be equipped with test cables and test computers. When the number of tested interfaces is large, more test cables and test computers are required. , there is no need to conduct a complete physical test on the entire serial port or IO channel. It is only necessary to test whether the serial port controller and the IO controller are working normally to meet the requirements. At this time, the same number of test cables and test computers as the number of interfaces to be tested can be equipped. is too complicated
