Description
Enable rx_10g_frame_skip_err port
On/Off
When you turn this option On, the 10G
PCS includes the
rx_10g_frame_skip_
err
output port. This signal is asserted
to indicate the frame synchronization
has received an erroneous word in a
Skip control word location within the
Metaframe. This signal remains asserted
during the loss of block_lock and does
update until block_lock is recovered.
Enable rx_10g_frame_diag_err port
On/Off
When you turn this option On, the 10G
PCS includes the
rx_10g_frame_diag_
err
output port. This signal is asserted
to indicate a diagnostic control word
error. This signal remains asserted
during the loss of block_lock and does
update until block_lock is recovered.
Enable rx_10g_frame_diag_status port
On/Off
When you turn this option On, the 10G
PCS includes the
rx_10g_frame_diag_
status
2-bit output port per channel.
This port contains the lane Status
Message from the framing layer
Diagnostic Word, bits[33:32]. This
message is inserted into the next
Diagnostic Word generated by the
frame generation block.
Interlaken CRC32 Generator and Checker
CRC-32 provides a diagnostic tool on a per-lane basis. You can use CRC-32 to trace interface errors back
to an individual lane. The CRC-32 calculation covers the whole metaframe including the Diagnostic
Word itself. This CRC code value is stored in the CRC32 field of the Diagnostic Word. The following
table describes the CRC-32 parameters.

Description
Enable Interlaken TX CRC32 Generator
On/Off
When you turn this option On, the TX
10G PCS datapath includes the CRC32
function.
Enable Interlaken RX CRC32 Generator
On/Off
When you turn this option On, the RX
10G PCS datapath includes the CRC32
function.
Enable rx_10g_crc32_err port
On/Off
When you turn this option On, the 10G
PCS includes the
rx_10g_crc32_err
port. This signal is asserted to indicate
that the CRC checker has found an error
in the current metaframe.
