how do you define the 16-N width of the ???? vector?

[JimmyTW]

--##
sig1 : std_logic_vector(11 downto 0);
sigN : std_logic_vector(N-1 downto 0);
sig1assign : std_logic_vector(15 downto 0);
sigNassign : std_logic_vector(15 downto 0);

sigAassign = "0000" & sig1;
sigNassign = ???? & signN; -- how do you define the 16-N width of the ???? vector?
--##

sigNassign = signN + conv_std_logic_vector(0, 16);
