Abstract

The invention discloses an eye pattern testing method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining target data, and writing the target data into a target file; reading register data in the target file to a register; refreshing register data in the register into a memory, and performing eye diagram testing after refreshing iscompleted; according to the method, the register data in the target file can be read into the register. The target data is transferred through the target file, that is, the data is written into the target file firstly and then read to the register, so that the data in the register can be updated when the equipment works, the software modification compiling frequency and the equipment restarting frequency are reduced, parameters are updated in real time under the condition that the equipment is not shut down. The time required for eye pattern testing is reduced, and the testing efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of signal testing, and in particular to an eye diagram testing method, an eye diagram testing device, electronic equipment, and a computer-readable storage medium. Background technique [0002] Differential transmission is a signal transmission technology, which is different from the traditional practice of one signal line and one ground line. Differential transmission transmits signals on both lines. The amplitude of the two signals is equal and the phase difference is 180 degrees. opposite polarity. The signals transmitted on these two wires are differential signals. The eye diagram test is a test to test the quality of the differential signal. The eye diagram is a series of digital signals accumulated and displayed on the oscilloscope. It contains a wealth of information. From the eye diagram, the intersymbol crosstalk and noise can be observed. The influence reflects the overall characteristi...
