GT-Debugger Eye-Qualification

[alessandro.ottino]

Hello everyone,

I have been trying to perform the eye-qualification of a transmission link using GT-Debugger and IBERT+ following the guide found here: AR# 70915.

But I have encountered some problems.

Every time I run the commands from the TCL Console from the Vivado GUI, it tells me that rxout_div is not known in the dictionary, even though it has been sourced from the file insert_gt_dbg_hwproc.tcl

Giving this error

I am working with a VCU118ES-1, with 8 12.5Gbs, bidirectional link.

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

Thank you in advance for your help

Hi @alessandro.ottino,

your init step did not finish correctly. For GTY you would need to tell the tool if your line rate is higher or lower than 10Gbps as there are different settings necessary in both cases.

As you run with 12.5Gbps your init command should look like this:

igd_eyescan init cX0Y28 gty_linerate_smaller10=0

With this the run should be possible.

Thank you so much for your help.

Now it works as it should
