Quartus - altera_europa_support warnings

Why don't you provide a 'patched' version of "altera_europa_support_lib" file ?

All warnings are derived of following VHD function :

-- a_ext is the Altera version of the EXT function. It is used to both

-- zero-extend a signal to a new length, and to extract a signal of 'size'

-- length from a larger signal.

FUNCTION a_ext (arg : STD_LOGIC_VECTOR; size : INTEGER) RETURN STD_LOGIC_VECTOR IS

VARIABLE arg_copy : STD_LOGIC_VECTOR ((arg'length - 1)DOWNTO 0) := arg ;

VARIABLE result : STD_LOGIC_VECTOR((size-1) DOWNTO 0) := (others => '0');

VARIABLE i : integer := 0;

VARIABLE bits_to_copy : integer := 0;

VARIABLE arg_length : integer := arg'length ;

VARIABLE LSB_bit : integer := 0;

BEGIN

bits_to_copy := a_min(arg_length, size);

FOR i IN 0 TO (bits_to_copy - 1) LOOP

result(i) := arg_copy(i);

end LOOP;

RETURN(result);

END;
