JTAG Hardware cosimulation help for XC7A35T -arty board

Jump to solution

Hi,

    I have added board xml files from "https://reference.digilentinc.com/learn/software/tutorials/vivado-board-files/start", except system generator, board is able to connect and is programmble in vivado, SDK, ISE impact. After following the steps given in USER guides by xilinx, still system generator displays message "could not find JTAG device xc7a35ti",i have one more doubt regarding a file in xml {C:\Xilinx\Vivado\2017.4\data\sysgen\xml\jtagcosim_gui.xml} named as "jtagcosim_gui.xml" as shown below, should i edit them for connect it to through JTAG.

Please make sure you are using supported version of tools .

Pleae make sure  to invoke sysgen with clicking sysgen token

 

You can try with modifying the design . It should be fine  

Thanks and Regards

Hello gyaneshwar3,

Currently i'm facing same problem you have faced before. I'm also using Arty A7-35T board. I have installed the Digilent board definition files and generated the JTAG Cosim block. Unfortunately I got the same error as you mentioned. 

Could not find JTAG device xc7a35ti.Could not find JTAG device xc7a35ti.


    I have edited board.xml and part0_pin.xml files according to arty FPGA part and Hardware Co-simulation is working.

 


Can you please specifically mention the code snippet you have modified. It would be really useful.

 

Thank you.

Hi,

This will work, " I have edited board.xml and part0_pin.xml files according to arty FPGA part and Hardware Co-simulation is working." change the part name to "xc7a35ti" or "xc7a35t" according to your board FPGA part name

renaming the part in "board.xml" and "part0_pin.xml" solved nothing, more, the arty a7-35 is no longer present in the list from sysgen...
