Sure I can post the code for you. But first a few questions. What
polynomial do you want to use for the LFSR?

just a VHDL code for LFSR ( 8 bits )

LFSR <= LFSR (6 downto 0) & (LFSR(7) xor LFSR(6));

You should ensure the polynome fits your needs.

There is an online tool that generates a Verilog code for an LFSR with different polynomial sizes and coefficients. It's on "http OutputLogic dot com" [sorry, this site doesn't let me post a link in a regular way]

Hope that helps
