Hello every body; During the analysis and optimization of my project on Quarts 12, I found that there are some registers are removed and the reason are " Stuck at GND due to stuck port data_in "...

Thanks Mr Tricky for your reply

My Register instance like This

process(clk)

begin

if reset='0' then

sIn <= (others => (others => x"00"));

elsif rising_edge(clk) then

sIn <= state_In;

end if;

end process;
