--  bv_images package specification.

--

--  Functions that return the string image of values.

--  Each image is a correctly formed literal according to the

--  rules of VHDL-93.

--

--------------------------------------------------------------------------

package bv_images is

  -- Image of bit vector as binary bit string literal

  -- (in the format B"...")

  -- Length of result is bv'length + 3

  function image (bv : in bit_vector) return string;

  -- Image of bit vector as octal bit string literal

  -- (in the format O"...")

  -- Length of result is (bv'length+2)/3 + 3

  function image_octal (bv : in bit_vector) return string;

  -- Image of bit vector as hex bit string literal

  -- (in the format X"...")

  -- Length of result is (bv'length+3)/4 + 3

  function image_hex (bv : in bit_vector) return string;

end bv_images;
