Abstract
This paper describes the development of a software tool for simulating and generating fully parallel generic VHDL representations of Fast Fourier Transforms. Several fixed-point number optimizations are described with emphasis on maximizing speed and/or minimizing FPGA area. Twiddle factor bit precision and its effects on FPGA area usage are also explored.
