## Filename:    fftgen.v

##

## Project:     A Doubletime Pipelined FFT

##

## Purpose:     This is the main Makefile for the FFT core generator.

##              It is very simple in its construction, the most complicated

##              parts being the building of the Verilator simulation--a

##              step that may not be required for your project.

##

##              To build the FFT generator, just type 'make' on a line

##              by itself.  For a quick tutorial in how to run the

##              generator, just type './fftgen -h' to read the usage()

##              statement.
