Description
rx_crc32
/sink/rx_crc32
This active high signal indicates CRC-32 error
from the CRC checker.
rx_frame_lock
[lanes-1:0]
/sink/rx_frame_lock
This active high signal indicates that four
Interlaken synchronization words are found for
a given lane.
rx_is_lockedtodata [lanes1:0]
/sink/Interlaken_phy_ip_rx/sv_
ilk_inst
This active high signal indicates that the
transceiver channel PLL has locked itself to the
incoming data.
rx_cal_busy
/sink/Interlaken_phy_ip_rx/sv_
ilk_inst
Sink transceiver calibration status. This active
high signal can be used for debugging if the
reconfiguration controller is actively calibrating
during the initialization sequence.

Table 5-4: Error Conditions and Core Behavior
This table lists the error conditions that the core detect and their behavior in response to each condition.

Error Indication
Rate adaptation FIFO The source core
buffer overflow in
asserts the error flag
source interface
for one clock cycle.
Core Behavior
There is an overflow on the rate adaptation
FIFO buffer in the source interface. The core
behavior depends on the operation mode:
• Continuous mode—error is flagged once
an overflow is detected.
• Burst mode—error is flagged only when an
overflow occurs during burst data transfer
across the user interface.
