KCU1250 IBERT Getting Started Guide
Viewing GTH Transceiver Operation
After completing
Setting Up the Vivado Design Suite
, the IBERT demonstration is
configured and running. The status and test settings are displayed on the serial I/O link tab
in the Links window shown in
Figure 1-19
.
Review the line rate and RX bit error count. The line rate for all four GTH transceivers is
12.5 Gb/s (see Status in
Figure 1-19
). Verify that the there are no bit errors.
In Case of RX Bit Errors
If there are initial bit errors after linking, or as a result of changing the TX or RX pattern, click
the respective
BERT
Reset
button to zero the count.
If the
Status
column shows
No Link
for one or more transceivers:
• Make sure the blue elastomer seal is connected to the bottom of the Bulls Eye cable
(refer to
Figure 1-4
)
and the cable is firmly connected and flush on the board.
• Increase the TX differential swing of the transceiver (to compensate for any loss due to
PCB process variation).
• Click the respective
TX Reset
button followed by
BERT Reset
.
