High-speed signal equalization parameter optimization method and system and related components

Abstract

The invention discloses a high-speed signal equalization parameter optimization method, system and device and a readable storage medium. The method comprises: acquiring an original waveform of normal work under the topology of a current high-speed signal; setting a plurality of corresponding simulation environments corresponding to the plurality of groups of to-be-tested equalization parameters; performing a compensation test on the original waveform in each simulation environment to obtain a corresponding compensation result; and determining a compensation result with an optimal effect from all compensation results, and determining the to-be-measured equalization parameter corresponding to the compensation result as an optimal equalization parameter, so as to apply the optimal equalization parameter to the equalization equalization method. The corresponding simulation environment is set for each group of to-be-tested equalization parameters, the compensation test of the original waveform is performed in the simulation environment, and the to-be-tested equalization parameter with the optimal arrangement effect is selected as the optimal equalization parameter, so that the equalization parameter applied to equalization can achieve the optimal compensation effect.

Description

technical field [0001] The invention relates to the field of signal compensation, in particular to a high-speed signal equalization parameter optimization method, system and related components. Background technique [0002] At present, with the increase of the clock frequency in the packaging circuit, the rising edge of the signal is generally shortened, and the integrity of the signal is more likely to be affected, especially the different frequency components of the signal in the interconnection channel have different degrees of attenuation, and the higher the frequency, the greater the attenuation , resulting in a huge amplitude difference between the high frequency and low frequency of the high-speed signal, and then the signal has problems such as rising edge degradation, inter-symbol interference, and eye diagram collapse. If no processing is done, the receiving end cannot correctly restore and decode the signal, thus A misjudgment occurs due to a transmission error. ...

Problems solved by technology

However, the equalization parameters of equalization have many different combination settings. Whether the equalization parameters are suitable for the current chip needs to be tested in a test environment. Due to the cumbersome construction of the test environment, it is usually determined as the equalization parameters that pass the test. Default parameters, the default parameters can not guarantee the optimal effect of signal compensation
