Honored ContributorDoes anyone know how to get rid of the following message?
warning (10542): vhdl variable declaration warning at altera_europa_support_lib.vhd(340): used initial value expression for variable "arg_copy" because variable was never assigned a value Thanx for every notice!!
Honored Contributorhmm...I have never seen that before, is 'arg_copy' one of your design variables or is it a part of the altera lib file ??
Honored ContributorWith sopc and other automated code generations I get tons of warnings...
I wouldn't care as long as things work and keep managers off my shoulder.Honored ContributorHonored ContributorDon't get me wrong. I like my managers, they are under more pressure from those fat cats. But what I don't understand is why they always walk in pairs?
Honored Contributorit was just a funny statement. :)
there are some companies that are very strict about Warning messages during compilation for their products.Honored Contributorarg_copy is part of the libary:
-- 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;
