Do a search on the Xilinx web site for app notes on LFSR. Peter Alfke

yeah, but no LFSR visits all states.
You haven't seen the app note. Why can't it include the zero state with

I think there's something about linear feedback that requires the
cycle length to be odd.
Maximum length sequences of even order are perfectly possible, but they
require more feedback taps.
