Hi,
My simulation tool is spectre of Cadence. I try to obtain the data jitter from the eye diagram. The calculator has eyediagram function, in which there is a function 'horitontal opening.' The function can work very well when you do normal simulation, and it will return the value of your horizontal eye opening. However, a problem occurs when you sweep a variable. Supposely it should plot the eye opening versus your sweeped variable. But what I have obtained is that the calculator will plot all the eye diagram without calculate the horizontal eye opening. Since the value should be a scalar, it shouldn't happen. Are there any way to make this function sweepable?
Thank you!
