DAC with THDB-ADA on DE2-115

Hi LouisMig,

I don't see anything wrong with the code except a minor mistake about using the library. These library should not be together

use ieee.std_logic_arith.all;

use ieee.std_logic_unsigned.all;

or

use ieee.std_logic_arith.all;

use ieee.std_logic_signed.all;

or

use ieee.numeric_std.all;

I don't know what will happen if you will use them together like that. In our code, you should include these:

library ieee;

use ieee.std_logic_1164.all;

use ieee.numeric_std.all;

As I'm a bit hungry, I will eat something now :D But I wanna check if your simulated signal is correct, so can you show me the testbench simulation of the code with these signal:

DAC_DB (in binary) and clockR?

One more thing, are your sure the pins assignment for your DE0-70 is correct?
