I have a question relating to how an eye diagram is built step by step.
I read documents about eye diagram.
1. For ISI, the eye is formed by: superimposing successive waveforms to form a composite image
https://www.testandmeasurementtips.com/basics-eye-diagrams/
But, i don't know based on what criteria they cut a certain waveform of falling and rising edge. For example, when signal transitions from 0 to 20%VDDIO, how signals are put together in an eye diagram
2. For external trigger ISI or relative jitter, we will need external trigger signals, that external triggers will affect eye diagram formation in what ways?
Thanks
