FreeLists / si-list / [SI-LIST] SATA eye diagram - how much is too much

["Grasso, Charles" <Charles.Grasso@xxxxxxxxxxxx>]

Greetings!
 
I have a question regarding the interpretation of the eye diagram data vis a
vis
SATA.
 
How many violations of the eye does it take before a design is brought to a 
screeching halt? A follow up question:
 
Can eye violations be graded in terms of severity based on the location
of the violation (that is : at the outer bounds, or the internal eye
trapezoid )?
 
The basis of this question (naturally) is that I have SATA data that have
exactly 
one 1 violation at the outer bound of the eye at 1 minute of data capture.
Typical go/no go specification will determine that to be a fail. I am not so
sure.
Any insight would be greatly appreciated.
 
Thanks
 
Best Regards
