2D Unconstrained Nx1 Array

Question

I\'m trying to create a flexible array of constants. I want to use a 2D array which may sometimes be for example a 2x1, 2x2, 3x2 array etc. For example:

type         


        

Answer 1

I managed to compile the first example in the following ugly way:

type int_2d_array is array (integer range<>, integer range<>) of integer;
  constant M : positive := 2;
  constant nMax : positive := 1;
  constant n : int_2d_array(M - 1 downto 0, nMax - 1 downto 0) := ( (others => 1) , (others => 2) ); 

Strange behavior, indeed.
