Loopback Modes
The Stratix GX transceiver has built-in loopback modes to aid in debug
and testing. The loopback modes are set in the Stratix GX MegaWizard
Plug-In Manager in the Quartus II software. Only one loopback mode can
be set at any single instance of the transceiver block. The loopback mode
applies to all used channels in a transceiver block.
The available loopback modes are:

Serial Loopback
Serial loopback exercises all the transceiver logic except for the output
buffer and input buffer. The loopback function is dynamically switchable
through the rx_slpbk port on a channel by channel basis. The V
output reduced. If you select 400 mV, the output is tri-stated when the
serial loopback option is selected.
