I have binding warnings http://paste2.org/La9jIxbF with http://paste2.org/wnHDY0g3 How do I solve them ? even I modify the configuration as in http://paste2.org/bJZJPdWt , I have this error http://paste2.org/BLW1yg32

I have solved the binding compilation warning.

Now, I could not view the internal signal http://i.imgur.com/w4jwnN1.png even though I am using the formal format *ghw with http://paste2.org/mVMOJZYA , http://paste2.org/vpbvXcID , http://paste2.org/1pAZac73 , http://paste2.org/FDh4c6Av and http://paste2.org/UwgnBnds

Hi Marvin,

I don't know how to help you. I'm not at all familiar with the tools
you are using. I know I don't have this problem with Aldec Active-HDL.

Can you explain the problem you had initially and how you fixed it?
Others may have the same problem in the future. Likewise, when you fix
this problem please post what you found.

I have solved the previous problem because I have forgotten to compile subbytes.vhd and round_constant.vhd together with key_expansion.vhd

what does mutiple architecture means as in http://www.edaboard.com/thread360462.html ? How do I fix that ?

anything wrong with the compile order as in the makefile at http://paste2.org/Kv7vD8xL ?

I can't say if your compile order is good or not without going through
all the code. Any module that invokes another module must be compiled
*after* the invoked module has been compiled. At least that is how the
tools I use do it. They automatically scan the files looking for
dependencies and order the files appropriately.

I have never run into multiple architectures before, but I suppose it
means you have more than one architecture with the same name?

Other than an unneeded use clause for package numeric_std in key_expansion.vhd the only errors causing 'U's are in round_constant.vhd:

library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;


entity round_constant is
port
(
CLK : in std_logic;
key_load: in std_logic;
rcon: out std_logic_vector(31 downto 0)
);

attribute SIGIS : string;
attribute SIGIS of CLK : signal is "Clk";

end round_constant;

architecture EXAMPLE of round_constant is -- WAS key_expansion is

signal rcnt_next, rcnt: integer := 0;
-- signal rcon : std_logic_vector(31 downto 0) := (OTHERS => '0'); -- NAME
signal rcon_next : std_logic_vector(31 downto 0) := (OTHERS => '0'); -- CHANGED
begin


process(clk)
begin

if rising_edge(clk) then
if(key_load = '1') then
rcon <= x"01000000";
rcnt <= 0;
else
rcon <= rcon_next; -- ADDED
rcnt <= rcnt_next;
end if;
end if;
end process;

rcnt_next <= rcnt + 1;


process(rcnt_next)
begin

case(rcnt_next) is
-- when 0 => rcon <= x"01_00_00_00"; -- CHANGE rcon to rcon_next
-- when 1 => rcon <= x"02_00_00_00";
-- when 2 => rcon <= x"04_00_00_00";
-- when 3 => rcon <= x"08_00_00_00";
-- when 4 => rcon <= x"10_00_00_00";
-- when 5 => rcon <= x"20_00_00_00";
-- when 6 => rcon <= x"40_00_00_00";
-- when 7 => rcon <= x"80_00_00_00";
-- when 8 => rcon <= x"1b_00_00_00";
-- when 9 => rcon <= x"36_00_00_00";
-- when OTHERS => rcon <= x"00_00_00_00";
when 0 => rcon_next <= x"01_00_00_00";
when 1 => rcon_next <= x"02_00_00_00";
when 2 => rcon_next <= x"04_00_00_00";
when 3 => rcon_next <= x"08_00_00_00";
when 4 => rcon_next <= x"10_00_00_00";
when 5 => rcon_next <= x"20_00_00_00";
when 6 => rcon_next <= x"40_00_00_00";
when 7 => rcon_next <= x"80_00_00_00";
when 8 => rcon_next <= x"1b_00_00_00";
when 9 => rcon_next <= x"36_00_00_00";
when OTHERS => rcon_next <= x"00_00_00_00";
end case;

end process;

end architecture EXAMPLE;

Notice you had the entity name wrong in the architecture, I converted the architecture declarative part signal declaration of rcon to rcon_next, changed the assignments in the case statement in the process, and added an assignment to rcon from rcon_next in your register process.

Let's take those things one at a time.

That's true if using entity instantiation. It's not true if using
component instantiation. Components merely need to be compiled before
elaboration.

My experience has been that tools that try to guess the compile order
will violate the LRM if confronted by unusual conditions such as
configurations or multiple architectures for the one entity.
(BTW, I only really have experience with Xilinx and Altera tools. Other
tools may be better or worse. I'm not hopeful though.)

It's allowable to have multiple architectures (with unique names) for a
given entity. This is commonly done, e.g. for RAM models - you might
have a (quick to simulate) behavioural one, as well as a (slow to
simulate) one with accurate timing.

You can select between different architectures in multiple ways.
- You can specify the architecture name in an entity instantiation.
- You can use a configuration.
- If not specified, it will default to the most recently compiled
architecture.
