Description While compiling an example design Implementing OFDM Modulation and Demodulation in the Quartus® Prime Pro Edition Software, you might encounter the following error: Error (12006): Node instance "auk_dspip_r22sdf_top_fft_72_inst" instantiates undefined entity "auk_dspip_r22sdf_top_fft_72". Ensure that required library paths are specified correctly, define the specified entity, or change the instantiation. If this entity represents Intel FPGA or third-party IP, generate the synthesis files for the IP. Resolution To work around this problem, create a new variation of the FPGA FFT IP Core. Change the input data width to 16 with a maximum FFT size of 2048. Verify the settings, generate the FFT IP and instantiate in the top level wrapper file of the example design. Manually add all the files generated by FPGA FFT IP Core for successful synthesis. There is no plan to fix this problem in a future release of the Quartus® Prime Pro Edition Software.
