DRAM 2D Eye Test explanation

Jump to solution

Is there any updated documentation for the ZYNQMP DRAM DIAGNOSTICS TEST? The current document does not describe the 2D tests and how to interpret the results. For example :

 

Running 2-D Read Eye Tests

-----+-----+-----+-----+-----+-----+-----+-----+-----+

VREF | LL0 | LL1 | LL2 | LL3 | RL0 | RL1 | RL2 | RL3 |

-----+-----+-----+-----+-----+-----+-----+-----+-----+

  50 |  45 |  45 |  45 |  45 |  50 |  50 |  50 |  50 |

  51 |  46 |  46 |  46 |  46 |  50 |  50 |  50 |  50 |

  52 |  47 |  47 |  47 |  47 |  50 |  50 |  50 |  50 |

  53 |  48 |  48 |  48 |  48 |  50 |  50 |  50 |  50 |

 

How would you interpret the numbers 50 and 45 in the first row of this table?

 

Thanks

Hello,

Updated documentation should be provided in the next release and will have information on the 2D eye tests which will answer these questions.

Thanks,
Caleb

@frank_ma 

The most recent I have heard is that should be released with the next software release, so for now I would say wait until that has come out.  Let me know if you don't see the update in documentation at that time and I can investigate further.

Thanks,
Caleb
