Michael,
Please email me directly with your contact information, FAE name, distribution FAE, etc. so I may escalate your case. By entering a case in the hotline, and communicating your expectations, we know how to address the issue, and we can track it. It is is not resolved quickly, we can escalate the issue to a team of experts. Not dealing with a customer case is a serious issue for the support staff, and is dealt with accordingly. Without a case number, and a contact, no one is taking the issue seriously, as it is not in the system as a "problem."
FAEs may just consider this something that you may be 'playing' around with, and does not require their attention.
I will personnaly find out why the field organization has not provided you with the answer, but without a case open, I can tell you right now that is a major factor!
Visiting a RocketLab(tm), you could see many eye patterns on real boards.

Is the on line tool that has been checked to show that the simulated eye patterns are accurate, and represent the actual eye patterns on the thousands of combinations.
I would suppose that others could send you their eye patterns, but that is up to them to decide to take the time and effort to do that. As well, posting graphics on this newsgroup is highly discouraged (as the graphics will be removed -- text only) so they would have to respond to you directly, and we do not know if the email address that appears in your posting is valid (many are not due to spam problems).
My direct email is austin @ xilinx . com (without the spaces).
One last comment, if the driver is also not 100 ohms matched, then any discontinuities upon reflection will re-reflect back to the receiver. There are some devices out there with very low, or very high transmit impedances (not ours) that have this problem. In any system or standard, the SI engineering makes assumptions. The assumption here is that both the Transmitter and the Receiver are to be as good a match as possible, so as to minimize the distortion to the eye pattern from 'normal' (that is, unavoidable)impedance discontinuities from vias, connectors, series AC blocking capacitors, package, and die variations.
A simulation of an improper impedance transmitter will demonstrate this issue.

For all those who are reading this: do not let this happen to you! If you have an issue, get a case number! Follow the case progress on-line through our on-line tracking system. If at any poinht you feel progress is not satisfactory, ask to escalate the case (bumps it up the system to the next level of technical expertise). You are the customer: you are always right (by definition). We do not have a choice. If you ask, we must respond. And we do.
