Eye Qualification with GT-Debugger and iBERT+

Eye Qualification is crucial to evaluate the performance of a transmission link.

To do so, I am following the Xilinx guide AR# 70915, but I found some problems.

In the guide it is said that to perforform the eye qualification it is needed to source or paste line by line in the Vivado TCL console the eye_qualify.tcl script, found in the guide before, without any specifications of previous commands or routines.

Therefore, I just sourced the code and paste it line by line, without any previous commands.

In both the case, an error appeared when running the last command of eye_qualify.tcl, "report_ch_qual $gtlist $measber $mask $RJrms 0", with error "key "GTYE4" not known in dictionary".

I am running the code on a VCU118-ES1, with 8 bi-directional GTY links at 12.5Gb/s, using the bitstream created with GT-Debugger as described in the guide.

Is anyone having the same problem, or know any possible solution?

thank you in advance for your help.

Re: Eye Qualification with GT-Debugger and iBERT+

Try running this on an open implemented design?
