MGT/BERT Settings Panel
The MGT/BERT Settings panel contains a table that is made up of one or more vertical
columns and horizontal rows. Each column represents a specific active GTH transceiver.
Each row represents a specific control or status setting.
MGT Settings
The MGT Alias setting is initially set to the MGT number of the GTH transceiver, but can
be changed by selecting the field and typing in a new value.
The Tile Location setting denotes the X/Y coordinate of the GTH transceiver in the device.
The MGT Link Status indicator is displays the status of the link detection logic that is
connected to the receiver of a particular GTH transceiver channel. If the channel is linked
(green), the measured line rate is displayed. If the channel is not linked, it displays NO
Link (red).
The CPLL/QPLL Status indicator shows the lock status of the CPLL/QPLL that is
connected to the GTH transceiver. The valid states of this status indicator are CPLL/QPLL
LOCKED (green) or CPLL/QPLL NOT LOCKED (red).
The Loopback Mode setting controls the loopback mode of a particular GTH transceiver
channel. The valid choices for loopback mode are:
• None: no feedback path is used.
• Near-End PCS: the circuit is wholly contained within the near-end GTH transceiver
channel. It starts at the TX fabric interface, passes through the PCS, and returns
immediately to the RX fabric interface without ever passing through the PMA side of
the GTH channel.
• Near-End PMA: the circuit is wholly contained within the near-end GTH transceiver
channel. It starts at the TX fabric interface, passes through the PCS, through the PMA,
back through the PCS, and returns to the RX fabric interface.
• Far-End PMA: the circuit originates and ends at some external channel endpoint (for
example, external test equipment or another device) but passes through the part of the
GTH transceiver channel. For this GTH transceiver loopback mode, the signal comes
into the RX pins, passes through the PMA circuitry, and returns immediately to the TX
pins.
• Far-End PCS: the circuit originates and ends at some external channel endpoint (for
example, external test equipment or another device) but passes through part of the
GTH transceiver channel. For this GTH loopback mode, the signal comes into the RX
pins, passes through the PMA, through the PCS, back through the PMA, and returns
to the TX pins.
• Far-End Fabric: the circuit originates and ends at some external channel endpoint (for
example, external test equipment or another device) but passes through the entire
GTH transceiver channel and related fabric logic. For this GTH transceiver loopback
mode, the signal comes into the RX pins, passes through the PMA and PCS, through a
shallow fabric-based FIFO, back through the PCS and PMA, and finally returns to the
TX pins.
The Channel Reset button resets the GTH transceiver channel by clearing and resetting all
internal PMA and PCS circuitry as well as the related fabric interfaces.
