## 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.
