I’ve been trying to integrate the Questa into the simulation environment, and have had success simulating all the provided modules, with the exception of the FFT. Whenever I would run `make vsim`, it would generate the IP, and then I would run into the following error. \ `vcom -32 -93 -work xil_defaultlib ../../../../../build-ip/xc7z100ffg900-2/axi_fft/synth/axi_fft.vhd `\ `-- Loading package STANDARD`\ `-- Loading package TEXTIO`\ `-- Loading package std_logic_1164`\ `-- Loading package NUMERIC_STD`\ `** Error: ../../../../../build-ip/xc7z100ffg900-2/axi_fft/synth/axi_fft.vhd(56): (vcom-1598) Library "xfft_v9_1_6" not found.`\ `** Error: ../../../../../build-ip/xc7z100ffg900-2/axi_fft/synth/axi_fft.vhd(57): (vcom-1136) Unknown identifier "xfft_v9_1_6".`\ `** Note: ../../../../../build-ip/xc7z100ffg900-2/axi_fft/synth/axi_fft.vhd(59):`
I have done several steps in trying to resolve this. Originally I compiled the sim library through Vivado, so I tried to compile it through the `build_simlibs` command (which I know just does the same thing, but I thought I’d try it). I’ve tried adding in the `MODELSIM_LIBS="secureip xpm"` argument when calling the make file, I’ve tried downgrading to Modelsim DE, and regenerating the library with the exact version that matches the desired version for Vivado 2021.1 (2020.4). No matter what, it seems like it can’t resolve this issue. When I check the generated IP files, I see a xfft_v9_1_vh_rfs.vhd file (which is encrypted), so I’m unclear why it’s unable to find it. Has anyone had any trouble simulating this module? And any steps to try to resolve? Thank you.
