extracting jitter from an eye diagram

svilen

Hi,

I have a PRBS data signal from which I plot the eye-digram. So, this signal is strictly speaking not periodic. I need to find a way to extract total jitter from that eye-diagram (the width at the crossing point in the eye-diagram). I don't need to just simply go to viva, plot the eye-diagram and measure with the cursors the width. I need to integrate this measurement in an script (ocean script perhaps). Is there a function that can do all this? Or maybe a procedure that can be put in a script? Or even maybe a way to plot the jitter histogram at the crossing point of the eye-diagram? I'm using IC616-64b.500.132.

Thanks in advance.

  • Thanks Shawn,

    I actually found a different way using the eye-diagram assistant from where I can get the histogram of the threshold crossings. Then I can do cross on the right and left sides of the histogram at a level of 0.5 and thus extract its span which is the width (within certain accuracy) of the eye-diagram edge crossings.
