I am studying eye-diagram while questions raised up in my mind.
To my best understanding, eye-diagram superimpose outputs based on bit period (or Unit Interval). This assumes that a random 0-1 series is set as the input signal, and its output is squeezed into one bit period, right?
With that said, I have two questions:
1. For freq-domain solvers, how is eye-diagram being calculated?
2. What I am more concerned is: For all transient simulators, the initial period is not a steady state. (E.g. devices need to be charged and biased), thus the early outputs are actually not reflecting the system's steady performance. Shall eye-diagram include these initial responses? Or it is only valid for steady-state systems?
