How to interface my verilog code with FFT ip core

[Altera_Forum]

I'm working on an application that involves the FPGA to take in an analog signal through its onboard ADC and perform the FFT using the altera ip core. 

 So far, my understanding is the ip core generates a verilog module for just the FFT and I will have to instance it in my own code. First question: is that piece of understanding correct?  The verilog file that the core generated looked like:   // Generated using ACDS version 15.0 153   `timescale 1 ps / 1 ps module myFFT512 (  input wire clk, // clk.clk  input wire reset_n, // rst.reset_n  input wire sink_valid, // sink.sink_valid  output wire sink_ready, // .sink_ready  input wire [1:0] sink_error, // .sink_error  input wire sink_sop, // .sink_sop  input wire sink_eop, // .sink_eop  input wire [31:0] sink_real, // .sink_real  input wire [31:0] sink_imag, // .sink_imag  input wire [9:0] fftpts_in, // .fftpts_in  output wire source_valid, // source.source_valid  input wire source_ready, // .source_ready  output wire [1:0] source_error, // .source_error  output wire source_sop, // .source_sop  output wire source_eop, // .source_eop  output wire [31:0] source_real, // .source_real  output wire [31:0] source_imag, // .source_imag  output wire [9:0] fftpts_out // .fftpts_out   );    myFFT512_fft_ii_0 fft_ii_0 (  .clk (clk), // clk.clk  .reset_n (reset_n), // rst.reset_n  .sink_valid (sink_valid), // sink.sink_valid  .sink_ready (sink_ready), // .sink_ready  .sink_error (sink_error), // .sink_error  .sink_sop (sink_sop), // .sink_sop  .sink_eop (sink_eop), // .sink_eop  .sink_real (sink_real), // .sink_real  .sink_imag (sink_imag), // .sink_imag  .fftpts_in (fftpts_in), // .fftpts_in  .source_valid (source_valid), // source.source_valid  .source_ready (source_ready), // .source_ready  .source_error (source_error), // .source_error  .source_sop (source_sop), // .source_sop  .source_eop (source_eop), // .source_eop  .source_real (source_real), // .source_real  .source_imag (source_imag), // .source_imag  .fftpts_out (fftpts_out) // .fftpts_out   );   endmodule  How do I instance that module in my own code? I do not recognize the syntax of ".fftpts_out (fftpts_out) " at all. Where can I read up on this?

Instantiate the code by copy and pasting the second half of generated file (that you've included above) in your higher level module. Substitute, as necessary, the signal names in the parenthesis for signals available in your higher level module to make connections to/from the FFT module instance. 'myFFT512_fft_ii_0' will be the instance name.
