We are using XCVU3P device and running IBERT test at 28.05Gbps at GTY Quad 126. We see that on one of the lanes (MGT_X0Y8) is getting error in every 2-3 minute when PRBS-31-bit pattern is selected in Vivado, however, there are no errors observed with PRBS-15-bit pattern. What could be the reasoning behind the same? Can you please suggest us any steps for debugging the same?
Please note that we have built 4 such boards and we see this observation in only 1 board, the other 3 works fine at PRBS-31-bit pattern.
