The answer depends on what you want to know.
If you want to capture your basic channel characteristics under the
intended encoding scheme, then figure out your maximum run length and
pick a PRBS sequence that is long enough to capture that run length and
simulate the entire sequence.
If you are trying to do something like evaluation of crosstalk on the
eye, then brute force starts to get expensive in simulation time. The
brute force method is to use a different PRBS on each aggressor than the
victim, and then run the product of the two sequence lengths.
