Abstract

The invention provides a method and device for screening transmission characteristic parameters of a Serdes signal, and belongs to the field of Serdes signal information processing. The method includes the steps that a transmission characteristic parameter array serves as a center point, and testing is carried out in multiple dimensions in sequence to obtain the largest error-code-free space radius; when the largest error-code-free space radius is larger than an error-code-free space radius, the value of the error-code-free space radius is updated to the value of the largest error-code-free space radius, the number of maximum keeping times is reset, the transmission characteristic parameters corresponding to the updated dimension values are updated, the dimension values are updated, and then the step of obtaining the largest error-code-free space radius is performed; when the largest error-code-free space radius is smaller than the error-code-free space radius, the number of the maximum keeping times is updated, and when the number of the maximum keeping times is larger than a preset value, it is judged that the transmission characteristic array is the optimal transmission characteristic parameters. By means of the method and device for screening the transmission characteristic parameters of the Serdes signal, the efficiency of screening the transmission characteristic parameters is improved.

Description

technical field [0001] The invention relates to the field of Serdes signal information processing, in particular to a method and device for screening transmission characteristic parameters of Serdes signals. Background technique [0002] In the existing parameter screening, because the scope of the parameter space is relatively small, or the direction of parameter tuning is relatively clear, it is generally a full parameter space traversal. For scenarios with many parameters and a large amount of data, the efficiency of traversing the entire range is too low. For a parameter space of 16 × 64 × 32, each parameter scan waits 10 seconds, and it takes about 91 hours to scan the complete space. Or use the auto-negotiation mode to make the chip adjust the parameters by itself. Parameter selection is mostly based on empirical values ​​or chip recommended values. [0003] Existing parameter screening technologies are based on directional optimization and iterative screening based...
