Problems solved by technology

This method is a tentative simulation of each parameter, and its test efficiency is low; in addition, once the wrong parameters are selected for optimization, the price paid is also high. For example, if you choose to optimize the material of the PCB board, that is Replace with a board with a lower dielectric constant, and if the test results show that the eye pattern quality is not significantly improved, the cost of the board with a smaller dielectric constant is much higher than that of ordinary boards, which increases the cost of testing

Abstract

The invention provides a method, device and network equipment for optimizing an eye pattern. The method comprises the following steps: setting the maximum value and the minimum value corresponding to specified parameters of a transmission channel; according to the maximum value and the minimum value of the specified parameters, simulating the transmission channel so as to acquire an eye pattern corresponding to the maximum value and the minimum value of the specified parameters; according to the simulated eye pattern, respectively acquiring the degree of influence of the specified parameters on each characteristic parameter of the eye pattern; and according to the acquired degrees of influence, determining optimization trends of the specified parameters so as to optimize the transmission channel. By using the technical scheme, the eye pattern can be optimized specifically, the optimization efficiency and the success rate are improved, and the optimization cost is reduced.

Description

technical field [0001] The invention relates to network communication technology, in particular to an eye diagram optimization method, device and network equipment. Background technique [0002] In the field of network communication, due to the faster transmission rate and lower signal amplitude of serial signals, parallel signals are gradually replaced by serial signals. A high-speed serial communication system generally also includes three parts: a sending end, a transmission channel, and a receiving end. The transmission channel usually refers to a printed circuit board (Printed Circuit Board; PCB) wiring connecting the sending end and the receiving end. High-speed serial signals are transmitted in the form of bit streams, which are composed of several "0"s and "1", such as "101100...". High-speed serial signals will be attenuated during transmission, and the characteristics of PCB traces are direct factors that affect the transmission quality of high-speed serial signal...
