How it works
This takes a 4 bit LSFR confugred as a PRBS=X^3+X^2+1 Reset sets four DFF to zero to make sure the osiclation starts. This uses XNOR because there was a synth warning The outpus are for a 7 segment displant and the last out put is for the PRBS
How to test
Set the clock, pulse reser and it it should givne RBS stream.
