Enable DDC in FMCDAQ2 + kc705

Hi,

I am using KC705 & FMCDAQ2 combo. I would finally move to ZC706 + FMCDAQ2

I would like enable DDC in AD9680. My preferred configuration is given in ""Table 23. DDC Example Configurations"" Chip decimation ratio is 16 ie no of virtual converters 8.
I have referred to below link.

ez.analog.com/.../412002

In case of HDL design, ""you could modify the design to M=8 ""

Does that mean I need to edit projects\daq2\common\daq2_bd.tcl? What are the other parameters to change?

""
ad_ip_instance util_cpack2 axi_ad9680_cpack { \
NUM_OF_CHANNELS 2 \
SAMPLES_PER_CHANNEL 4 \
SAMPLE_DATA_WIDTH 16 \
}
""

to

""
ad_ip_instance util_cpack2 axi_ad9680_cpack { \
NUM_OF_CHANNELS 8 \
SAMPLES_PER_CHANNEL 1 \
SAMPLE_DATA_WIDTH 16 \
}
""


our requirement is similar to ""Example 2: ADC with DDC Option (Two ADCs Plus Four DDCs)"" in AD9680 data sheet.

As i understand, we may have to reduce no of lanes to 2 from given default 4 lanes in example design to maintain minimum lane rate of >3.125Gbps.

Is there any guidelines to reduce the lane nos in HDL design? Do I need to just edit daq2_bd.tcl?

  • Hello,

    You just need to edit the daq2_bd.tcl file in the common directory. Since the architecture construction is parameterized you just need to modify the variables defined in the beginning of the file: set RX_NUM_OF_LANES 2 ; # L
                                                                                 set RX_NUM_OF_CONVERTERS 8 ; # M
                                                                                 set RX_SAMPLES_PER_FRAME 1 ; # S
                                                                                 set RX_SAMPLE_WIDTH 16 ; # N/NP

    Best Regards,

    Dan Hotoleanu

  • I believe that hdl version (hdl_2019_r2) does not support changing following parameter

    ad_ip_parameter axi_ad9083_rx_jesd/rx CONFIG.TPL_DATA_PATH_WIDTH 8


    "hdl/library/jesd204/jesd204_rx/jesd204_rx.v" has only following paramters


    module jesd204_rx #(
    parameter NUM_LANES = 1,
    parameter NUM_LINKS = 1,
    parameter NUM_INPUT_PIPELINE = 1,
    parameter LINK_MODE = 1, // 2 - 64B/66B; 1 - 8B/10B
    /* Only 4 is supported at the moment for 8b/10b and 8 for 64b */
    parameter DATA_PATH_WIDTH = LINK_MODE == 2 ? 8 : 4,
    parameter ENABLE_FRAME_ALIGN_CHECK = 1,
    parameter ENABLE_FRAME_ALIGN_ERR_RESET = 0
    ) (

    I would request you to suggest the branch i need to checkout inorder for changes suggested to take effect.


    Is it possible for me to update jesd204_rx of (hdl_2019_r2) with verion from master branch?

  • Can Expect an update for this request?? I am still stuck at this point.

  • Hello,

    I created two branches on git where I've modified the daq2 hdl and linux project. The modification is not tested on hardware. The hdl part is available here: https://github.com/hotoleanudan/hdl/commit/d4b259bc967696cd74d6774810d728b8f04b08bb  and the linux part is available here: https://github.com/analogdevicesinc/linux/commit/22306c385556075a215e21a5b0c40760cca79cd0 . 

    Best Regards,

  • Hello Dan,

    I tried building hdl using Vivado 2020.1

    I encounter the following error while building project.

  • Hello,

    Can you please make a fresh clone of the hdl repository on my fork https://github.com/hotoleanudan/hdl and switch to daq2_without_ad9144_proj branch and then build the daq2/zc706 project?

    Thank you.

    Best Regards,

    Dan

  • Hi,

    As of now I do not have zc706 hardware with me. So i tried building for kc705 + fmcdaq2.
    I could build project and boot it on kc705.

    I could observe AD9680 on IIO scope but could not find any waveforms in capture

    In dts file I could not find include for XCVR_REFCLK_DIV1 so edit was follows
    ""
    axi_ad9680_adxcvr: axi-ad9680-adxcvr@44a50000 {
    compatible = "adi,axi-adxcvr-1.0";
    reg = <0x44a50000 0x10000>;

    clocks = <&clk0_ad9523 4>;
    clock-names = "conv";

    adi,sys-clk-select = <XCVR_CPLL>;

    adi,out-clk-select = <XCVR_REFCLK>;
    adi,use-lpm-enable;
    adi,vco-max-khz = <5000000>;
    ""

    I am also attaching boot-up print Linux print


    "jesd204: found 0 devices and 0 topologies" which I have not seen in working versions

  • I attached ILA to util_adcfifo adc_wr data and adc_wr in ILA I could not trigger for adc_wr or adc valid 

    when probed for clock freq I got 

    device_clock = 31.25MHz  i guess it should be 62.5MHz

    Link clock = 250MHz i guess it should be 125 MHz

    I guess In system_top.v

    IBUFDS_GTE2 i_ibufds_tx_ref_clk (
    .CEB (1'd0),
    .I (tx_ref_clk_p),
    .IB (tx_ref_clk_n),
    .O (),
    .ODIV2 (device_clk));

    Could be the issue

    in case of link clock I may have to edit dts for div2

  • I changed 

    device_clk generation in system_top.v to

    IBUFDS_GTE2 i_ibufds_tx_ref_clk (
    .CEB (1'd0),
    .I (tx_ref_clk_p),
    .IB (tx_ref_clk_n),
    .O (device_clk),
    .ODIV2 ());

    in dts

    maintained 

    adi,sys-clk-select = <XCVR_CPLL>;
    adi,out-clk-select = <XCVR_REFCLK_DIV2>;

    Once these changes made

    device_clk = 62.5MHz

    link_clk = 125MHz

    In ILA attached there is still  no data 

  • I guess when I read 

    0x570 register for AD9680 using IIO . it  has a value 0f 0x88 (default configuration)

    This shows 

    L= 4 expected 2

    M = 2 expected 8

    F = 1 expected 8

    So AD9680 may not be configured properly . How to do this??

    While building linux kernel I has used Vivado SDK 2019.1? Will that be the problem

    I also tried capturing data from util_xcvr_rxdata which showed a constant value

  • Hello,

    I will test the modified architecture of daq2 on the zc706 board and I will give you a feedback.

    Best Regards,

    Dan

  • I guess the reason for AD9680 to be in default 4 lane mode could be due how these parameters are set in driver ad9680.c

    Here Lane number and other JESD related parameters are hard coded in ad9680.c driver. So in order to configure ADC I may need to edit driver. I have tried editing ad9680.c

    With this change i could observe proper values in AD9680 registers.

    But still I do not get any output at FPGA side. So i guess AD9680 is not configured properly to transmit data to FPGA.

    Please help

  • Hello Dan,

    Any updates??

    Regards

    Rakesh M.

  • Hello Dan,

    Any updates?? Could you test modified architecture on zc706

  • Hello Rakesh,

    Sorry for not replying earlier.

    We're trying to get to a working configuration on our side, but we still haven't got it to work. 

    We'll keep you updated with the progress.

    Regards,

    Adrian

  • Our zc706 board has arrived.... In case of any updates I can directly try on those boards.

  • Hello,

    We are still working on the issue, we were not able to bring up out of CGS the link.

    Regards,

    Adrian

  • Hello, 

    after a review of the changes we found that in the above mentioned design the following line is incorrect:

    ad_ip_parameter axi_ad9680_jesd/rx CONFIG.DATA_PATH_WIDTH 8

    The correct value for DATA_PATH_WIDTH  must be 4.  This can be the cause of staying in CGS mode. 

    We are investigating the software too.  We will attempt to bring up the link with Linux. 

    Thank you,

    Laszlo
