Data input verification method and data input verification structure

A data input verification method, comprising:

• generating a randomly combined input character string;
• generating a test input signal inputted to a receiver of a memory based on the input character string and a simulated inter-symbol interference value, wherein the simulated inter-symbol interference value is an estimated value of inter-symbol interference transmitted from an output end of a memory controller to the receiver;
• inputting the test input signal into the receiver and obtaining an output signal of the receiver;
• and
• determining whether a character string represented by the output signal is equal to the input character string, and generating an eye diagram of the output signal;
• wherein, in generated test input signal, a consecutive non-initial character “1” corresponds to a preset positive swing amplitude, a non-consecutive character “1” corresponds to an interference positive swing amplitude, a consecutive non-initial character “0” corresponds to a preset negative swing amplitude, and a non-consecutive character “0” corresponds to an interference negative swing amplitude;
• a value of the preset positive swing amplitude is greater than a value of the interference positive swing amplitude, and a value of the preset negative swing amplitude is less than a value of the interference negative swing amplitude.
