In-System IBERT - eye diagram status incomplete

Jump to solution

Hi,

 

I am using the in-system IBERT Tool according to the example from the product guide (PG246) with two Aurora IP cores. The two transceivers (instantiated by the two Aurora IP cores) are sending data to each other (simple counter values). I can see in the hardware debugger, that the channel is up; I am also receiving data as expected, however whenever I run the scan on the link of the transceivers, I always get the status: incomplete. How do I know, which parameters I need to change to make an eye diagram scan? I already tried resetting the scan by setting EYESCANRESET_OUT to 1 and back to 0 (from the link properties) but it didn't seem to help.

 

Thanks in advance!

Hi @ida,

did you have a look at ug908, chapter 14 and 15?
There you can find more information on how to use IBERT.

Hi,

 

Thank you for your reply. I did look at those chapters but as far as I understood they are using the IBERT tool, which cannot be added as an IP core to the block design in Vivado (the in-system IBERT IP core can be added). Nevertheless, I added it according to the example design and I could test the quality of my communication and plot the eye-diagram. I'm going to mark your answer as accepted.
