How to interface my verilog code with FFT ip core

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?
