Did you look through the simulation libraries that you built to see if xfft_v9_1_6 is in there? I'm wondering if it's not there or if ModelSim just can't find it.
Take a look at the manual page if you haven't already: https://files.ettus.com/manual/md_usrp3_sim_running_testbenches.html Let's assume it can't find it. When you run "source setupenv.sh" to setup your environment, there's a --modelsim-path option to say where modelsim is located. It'll tell you if it successfully found modelsim and if it found the compilation libraries. If it can't find the simulation libraries, I think you can try setting the environment variable MSIM_VIV_COMPLIBDIR to point to the directory where they are located. If setupenv.sh can find modelsim and the libraries then "make vsim" should work, assuming you did indeed compile all the required libraries. If that doesn't work, and you confirmed the library is there, here are some other options. When you compile the simulation libraries using Vivado, it generates a modelsim.ini with the required library mappings. Make sure the library is listed in there and that the path is correct. You can set the environment variable MSIM_MODELSIM_INI to point to the generated modelsim.ini file. Or, you can also open the generated modelsim.ini and copy the library references manually to your main modelsim.ini (this is what I typically do).
