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

  • 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
