FFT Megacorefunction in Altium Designer

Hello,

I've generated a FFT Megacorefunction in Quartus II v. 9.1 with the Mega Wizard Plug-In Manager. I had no problems with the Synthesis in Quartus II.

Now, I want to use the FFT Megacorefunction in Altium Designer. I've implemented all *.vhd Files from the Altera Project folder, but I always get an error message:

Document: asj_fft_1 dp_ram_fft_91.vhd

Message: syntax error near 'I'

    the MegaCore source libraries are usually encrypted, so the simulator can't read them

    in the MegaWizard you need to enable simulation netlist generation which will create a <fft_variation_name>.vho/.vo. use this file for simulation rather than the <fft_variation_name>.vhd/.v along with the library files

    oops, i didn't read that you're using Altium

    i suspect the problem is that the files are encrypted, i'm not sure how you're supposed to use IP in Altium
