Rather than just posting demands for code, try doing some research of your own first, and then ask questions when you have tried to do some work and hit a problem.

words like 'please' would be fine

Hi Helina,

find the VHDL code for LFSRs there: http://sciencezero.4hv.org/science/lfsr.htm[^], the site also has the codes for MMX, ARM, C++ and BASIC.

VHDL code for a LFSR
vhdl
signal lfsr : std_logic_vector(14 downto 0);
lfsr <= lfsr(13 downto 0) & (lfsr(14) xnor lfsr(0)); 


You may need to adjust for register length and tap points.

Best Regards,
Manfred
