I am actually writing my own FFT module in which is 128-points FFT size. I am using floating-point as I have found the library in Quartus II. Are there any libraries for fixed-point implementation?

By the way, what if I have a VHDL design that I want to use as a component. And this VHDL design has many I/O ports as well. What is the best way to perform compilation and simulation? Is it using Virtual Pins as mentioned by thepancake?
