Abstract

The present invention proposes a method for equalizing high-speed waveforms, which is used to solve the technical problem of low versatility in the prior art that can only achieve equalization of differential high-speed waveforms or single-ended high-speed waveforms, and at the same time shorten the time required for differential high-speed waveforms. The equalization time, the implementation steps are: obtain the parameter value of the high-speed waveform; extract the AMI file, DLL file and file name of the AMI model; write the header file name of the function in the DLL file; obtain each DLL file in the AMI model based on MATLAB simulation software The input parameters and each input parameter value of the function; obtain the input parameters and each input parameter value of each function in the DLL file; obtain the AMI_INIT function and the output waveform of the AMI_GETWAVE function of the DLL file in the AMI model based on the MATLAB simulation software; determine the output waveform Rules of use; based on MATLAB simulation software to obtain the eye diagram of the balanced high-speed waveform.

Description

technical field [0001] The invention belongs to the field of computer technology, and further relates to a high-speed waveform equalization method based on an AMI model in the field of computer high-speed link equalization technology, which can be used in the field of general I / O interfaces of high-performance computers and communication equipment. Background technique [0002] In the high-speed full link, when the rising edge in the transmitter is less than 1ns, the transmitter will send a high-speed waveform. There are two ways to generate high-speed waveforms: one is a single-ended high-speed waveform generated by a single-ended transmitter; the other is a differential high-speed waveform generated by a differential transmitter. When the generated high-speed waveform passes through the transmission channel, it will be affected by ISI (InterSymbol Interference), crosstalk and attenuation, so that the receiver cannot accurately identify the high-speed waveform generated by ...
