add an fft testbench
make sure dft_reset actually triggers
make sure recomb_tb checks done and write_en signals
add fft_tb to testbench list
in recomb testbench make sure data is actually being written
change the way the done signal is handled in fft_recomb
make sure reset and done checking is timed correctly
reset the fdom ram before beginning dft computations
testbench the fdom ram
give fft_fdom_ram a more sensible port ordering
check readaddr and readdata in fdom_ram_tb
switch testbench to fdom_ram_tb
separate entity for each row of fdom ram
initialize everything at beginning of fdom_ram_tb
add fft_fdom_ram_row to qsf file
change fft_tb test data
