Unique constant per instantiation

Good morning! Is there a way to generate a constant that is unique per call to the function? I want something like this: architecture ... constant c_myid : std_logic_vector(31 downto 0...

I don't care about what ID they get, only that the IDs be distinct.

Are you sure that a function always returns a constant? When I use a function like "a <= f(b, c);" with signals a, b, c the result is clearly varying. I admit to never having tried "constant a := f(b, c);" with signals b, c. If it's syntactically correct, then I suppose it must be based on the initial values of the signal. So maybe your shared variable approach should work. Confused.
