Guidelines to use Eye Viewer feature for Stratix 10 SoC Dev Kit

Hi,

I went through the online tutorial and tried to run the TTK (Transceiver Tool Kit) in Stratix 10 SX dev kit. While checking with TTK, I observed that eye viewer takes significant amount of time to capture the data and plot the graph.

Currently I set the receiver PMA settings to Manual CTLE, Manual VGA , DFE Off mode since I am observing that 0 BER with this mode [VOD=31, Pre-emphasis pre & post tap are 0; VGA DC gain = 4, CTLE EQ Gain is 18 and CTLE AC Gain is 6]

I configured TTK with "PRBS7" and "Don't run longer than 5 seconds" and Horizontal & Vertical step interval ='4'.

It took around 15 minutes to give out the heat map .

I understand that it will take more time if I reduce the Horizontal & Vertical step interval to '2' or '1'. Apart from this whether the time to plot will increase by either setting PRBS31 or making RX Adaption mode to Adaptive or if I increase the duration in case of "Don't run longer than 5 seconds" ?

With regards,

HPB
