Hello, I'm trying to use the AD2 pattern generator to create a (digital) sine wave using a value table table. I connected the external trigger to a clock of 10MHz, to create a sine with the frequency of 10/1024 MHz (with 1024 being the size of the table). When I compare the resulting sine wave to a sine wave generated by an FPGA, using a look-up table with the same size and clock, I see that both signals drift apart from each other, even though both of them seem to have the same period. Am I using this tool the wrong way? Is my setting for a trigger wrong somehow? -
i want to generate sine wave on dac (pmodda3)(http://www.analog.com/media/en/technical-documentation/data-sheets/AD5541A.pdf)and i am using spartan3e but there ara several warnings ,How can i fix the warnings? i loaded code and picture. help me please ---------------------------------------------------------------------------------- library IEEE; use IEEE.STD_LOGIC_1164.ALL; use ieee.std_logic_arith.all; use ieee.std_logic_signed.all; use ieee.numeric_std.all; entity kecelikalem is port( clk: in STD_LOGIC; reset : in STD_LOGIC;
