Markers on Eye Diagrams IC615 vs IC514

miscrms

Can anyone tell me how to place markers on an eye diagram in IC615? 

We used to do this routinely in IC514 using the eyeDiagram() function in the calculator to plot the wrapped data and then using the a and b markers to make various measurements (amplitude, overshoot, jitter, rise/fall time etc).  The marker/cursor would automatically hop to whatever trace you put the mouse over as expected.  In IC615 we have tried using eyeDiagram() from calculator and the Measurements -> Eye Diagram tool from the plot window with the same result for both.  The markers will only snap on the first trace (data from 0 to the first wrap period interval), not the additional wrapped eye diagram traces. 

For example, for the plot "eyeDiagram(VT("/out") 2n 17n 120p)" the tracking cursor as well as any of the markers will only show values along the trace data from 0-120ps which is not even part of the displayed waveform as we're omitting all the data prior to 2ns.

Thanks,

Rob

    Rob,

    Which subversion are  you using? There were some issues with markers on eye diagrams in early IC615 ISRs, but from my tests just now in ISR9 (the latest hotfix - 6.1.5.500.9) the markers (added with the "m" bindkey or a-b markers with the "a" or "b" bindkeys) work correctly and snap to any of the folded periods. The tracking cursor works OK too.

    Regards,

    Andrew.
