3D eye measurement in Transceiver toolkit using Stratix V

Hello, 

 

I'm Insun. I'm a beginner of Stratix. 

I've measured 3D eye contour using Stratix V for testing signal integrity. 

However, I don't know how can i convert the "eye width" and "eye height" into real dimension like time and voltage. 

I already read a related document "overcome high-speed I/O verification challenges with Stratix V on-die instrumentation" which explains about the 3D eye measurement and concept of phase and vertical steps. 

And I understood the concept of phase and vertical steps. 

But I need to know the time and voltage of eye width and eye height results, not just sampling steps.  

 

Please help me to get the answer.  

Thank you.
