On / Off When you turn on this option, the Enhanced PCS frame
synchronizer is enabled.
5-8192 Specifies the metaframe length of the frame synchronizer.
On / Off Enables the rx_enh_frame status output port. When the
Interlaken frame synchronizer is enabled, this signal indicates the
beginning of a new metaframe. This is an asynchronous signal.
On / Off Enables the rx_enh_frame_lock output port. When the
Interlaken frame synchronizer is enabled, this signal is asserted to
indicate that the frame synchronizer has achieved metaframe
delineation. This is an asynchronous output signal.
On / Off Enables therx_enh_frame_diag_status output port. When the
Interlaken frame synchronizer is enabled, this signal contains the
value of the framing layer diagnostic word (bits [33:32]). This is a
2 bit per lane output signal. It is latched when a valid diagnostic
word is received. This is an asynchronous signal.
Range
On / Off When you turn on this option, the TX Enhanced PCS datapath
enables the CRC32 generator function. CRC32 can be used as a
diagnostic tool. The CRC contains the entire metaframe including
the diagnostic word.
On / Off When you turn on this option, the error insertion of the interlaken
CRC-32 generator is enabled. Error insertion is cycle-accurate.
When this feature is enabled, the assertion of
tx_err_ins
incorrectly inverted, and thus, the CRC created for that metaframe
is incorrect.
On / Off Enables the CRC-32 checker function.
On / Off When you turn on this option, the Enhanced PCS enables the
rx_enh_crc32_err port. This signal is asserted to indicate that
the CRC checker has found an error in the current metaframe.
This is an asynchronous signal.
