Array Problem

[Günther (Gast)]

Ich versuche einen std_logic_vector in ein array zu schreiben.
Warum bekommt ich immer wieder diesen Fehler????

ERROR:HDLCompiler:410 - 
"E:\Schmid\2013_14_10_Lady_V6_5th_16Pixel_Reg_TTF\V6_Code\vhd\DDC264.vhd 
"  Line 161: Expression has 0 elements ; expected 16

type t_data_DDC246      is array (0 to 59) of std_logic_vector (15 downto 0); -- aus einem Package


entity DDC264 is
    Port ( clk : in  STD_LOGIC;
    ...
           data_o : out  t_data_DDC246);
end DDC264;

-- code

signal s_data : std_logic_vector (1023 downto 0);

-- code

end process;

data_o(0) <= s_data (15 downto 0);
data_o(1) <= s_data (640 downto 655);
data_o(2) <= s_data (528 downto 543);
data_o(3) <= s_data (544 downto 559);
data_o(4) <= s_data (560 downto 575);
data_o(5) <= s_data (672 downto 687);

Hi!

Alles richtig aber Du musst die Werte umdrehen. Du schreibst ja down 
to!!!

data_o(1) <= s_data (655 downto 640);
