use ieee.std_logic_arith.all;
entity onesusingloop is
port(d:in std_logic_vector(9 downto 0);
count:out integer);
end onesusingloop;
architecture beh of onesusingloop is
begin
process(d)
variable x:integer;
begin
x:=0;
for i in 0 to 9 loop
if(d(i)='1')then

end process;
end beh;
The above code has been executed and has been found to have no errors..!
plz do comment..!
