## Filename:    Makefile
##
## Project:     A General Purpose Pipelined FFT Implementation
##
## 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.
##
