Custom board with 2 AD9361 and problem with IODELAY GROUP


My team and I plan to connect our own RF board containing two AD9361 used only for their RX pins to a ZC706 platform. However compared to the FMCOMMS3 board in which each of the AD9361 is connected to a different FMC Connector, we use only one FMC connector. I used the design provided by AD for ZC706, but when I changed the pinouts to match my board (see enf of the post), I have the following error : 

I saw one of the topics that mentionned the patch : ad9361_iodelay_ctrl.patch and I did the modification described in it. But I ended up with this error : 

Can you please help me find a solution ?

Thanks in advance ! 

PS : Here is the pinout I used :

    You will likely need to disconnect the the delay_rst signal in the IP that has IODELAY_CTRL  set to 0 and route it from the IP that has the IODELAY_CTRL set to 1.  

    What version of Vivado are you using?


  • Actually I don't really know where to look in order to answer your question. I used the design provided by AD and it seems in what I can see that there is only one delay_rst signal everywhere.. Do you know where I can look ? 

  • So basically, I have to do the modifications as described in the patch but create two IODELAY_CTRL parameters, one equal to 1 and the other equal to 0 ? IODELAY_CTRL_0 for one of the IP and IODELAY_CTRL_1 for the other IP ? Is that correct ? 

  • No, actually, I dont see where I can set two different IODELAY_CTRL. Here is my axi_ad9361.v code for example...

    step 1)  Apply the patch to the axi_ad9361 as is (the file attached);  This will add a new parameter to the IP that you can set differently in each instance of the IP.

    step 2) You need to set the parameter in the block design/top level file where you instantiate the two axi_ad9361

    For the IP where you set the IODELAY_CTRL to zero, make sure to set the IODELAY_GROUP to the same value as the other IP that has IODELAY_CTRL to one.

    In your case dev_0_if_delay_group.
