PRBS mode has two pattern generator options, selectable in the BIST tab of the
MegaWizard Plug-In Manager when you choose PRBS as a sub protocol under Basic
functional mode.

PRBS7, PRBS8, PRBS10, and PRBS23 generator and verifier—This is the generator
and verifier interface with the serializer and deserializer in the PMA blocks. The
advantage of using a PRBS data stream is that the randomness yields an
environment that stresses the transmission medium. In the data stream, you can
observe both random jitter and deterministic jitter using a time interval analyzer,
bit error rate tester, or oscilloscope.
High-frequency and low-frequency pattern generator—The high-frequency
patterns generate alternate ones and zeros and the low-frequency patterns
generate five ones and five zeroes in single width mode, and ten ones and ten
zeroes in double width mode. These patterns do not have a corresponding verifier.
The PRBS repeats after completing an iteration. The number of bits the PRBSx
pattern sends before repeating the pattern is (2^×-1) bits. This mode is available as
a sub protocol under Basic functional mode.
