Hi ,

I am able to run my transceiver example design with transceiver toolkit.

I performed an auto sweep and eyeviewer on the transceiver links.

I am able to see the BER 0 and best PMA settings in Transceiver link channel manager.But when I open the heat map window the eyediagram is just a small blue line at the center with eyewidth/height ratio 1.

Please let me know what could be reasons for this?

I could see in Strartix 10 device errata that "On-die instrumentation (ODI) (Eye-Q) is not available in Intel Stratix 10 devices that use the transceiver L-tile".

Does this mean that eye diagram cannot be plotted for L tile strartix 10 devices?

I am using 1SG280LN2F43E2VG (L- tile device) in my design.
