Not knowing the specifics of how this all works, shouldn't an eye center be located at the mean of the horizontal(time) and vertical(voltage) sampler probability distributions, since I assume that the computed sampler PDF has been included in the computation for the effective eye after sampling.

Sorry for my poor problem statement... I mean the output of Rx (as it comes back from Rx GetWave), used together with the clock ticks from Rx GetWave to formulate the eye.

How does the user decide whether the eye is good or bad? Naturally we have this thing called eye mask (template) which we would all be able to drop into the eye without touching any of the waveforms. But where are we trying to position it? Anywhere it fits the best way? Or is it supposed to be positioned at a certain location? Thanks for any feedback in advance, Arpad ========================================================= --------------------------------------------------------------------- IBIS Macro website : http://www.eda.org/pub/ibis/macromodel_wip/ IBIS Macro reflector: //www.freelists.org/list/ibis-macro To unsubscribe send an email: To: ibis-macro-request@xxxxxxxxxxxxx Subject: unsubscribe--------------------------------------------------------------------- IBIS Macro website : http://www.eda.org/pub/ibis/macromodel_wip/ IBIS Macro reflector: //www.freelists.org/list/ibis-macro To unsubscribe send an email: To: ibis-macro-request@xxxxxxxxxxxxx Subject: unsubscribe
