Hi Arnaud,Thank you very much for your reply, I didnt know that. Anyway, here we can only see the base address for each main component of the project, but if it is possible, I would like to know as well the detailed map address of the FMC local devices. I mean, the start address of the FMC176 in this project is 0x2404, but then for example, there are three different start address to configure the AD9250 described in file fmc176_if_v7.vhd--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------constant START_ADDR_AD9250_PHY : std_logic_vector(27 downto 0) := START_ADDR + x"0000010";constant STOP_ADDR_AD9250_PHY : std_logic_vector(27 downto 0) := START_ADDR + x"00000FF"; --min. range 16#0010constant START_ADDR_AD9250_CTRL0 : std_logic_vector(27 downto 0) := START_ADDR + x"0000100";constant STOP_ADDR_AD9250_CTRL0 : std_logic_vector(27 downto 0) := START_ADDR + x"0000200"; --min. range 16#0011constant START_ADDR_AD9250_CTRL1 : std_logic_vector(27 downto 0) := START_ADDR + x"0000300";constant STOP_ADDR_AD9250_CTRL1 : std_logic_vector(27 downto 0) := START_ADDR + x"0000400"; --min. range 16#0011--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------What are these different addresses for? According to AD9520 datasheet, the settings map address of this ADC only needs 0xFF addresses at most. I guess you use different base address for different AD9520 settings? So, which AD9250 settings are programmed in each of the ADDR_AD9250_PHY, ADDR_AD9250_CTRL0 and ADDR_AD9250_CTRL1 addresses?For the AD9129, it is the same. The settings map address of these DACs only requires 0x7F addresss, but there are more available addresses in the fmc176_if_v7.vhd file. Could you please tell me which settings are programmed in each of the ADDR_AD9129_PHY0 and ADDR_AD9129_CTRL0?Thank you very much in advance for your help,Angela
