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;
