I am working on FMCOMMS4 board and using the fmcomms2 project. I need to make some changes in the reference design. So where can i find the HDL testbench for AD9361 IP?
There is a system level testbench that you could adapt to your needs.
Have a look here: https://github.com/ronagyl/testbenches/tree/main/fmcomms2
This repo must be cloned inside the hdl repo.
