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?
