This is the top level of the 2v6000 virtex2 fpga for galfa.

The makefile at this level should build the entire chip
from scratch and leave the bitfile image in
build/gk6_r.bin.gz (or build1/...).

There is an open office spreadsheet of chip resources
in budget.xls.

The directories are as follows:

src The source code for the chip is here. The top level
is gk.v and the lower level modules are in files
named the same as the module. Some major sections
of the chip are generated by perl scripts and kept
in separate directories as follows.

n_cmix The complex mixer for the narrowband signal path.
Generated by jfft.

n_lpf The lowpass filter for the narrowband signals path.
Generated by jfft.

n_pfb The 8k decimated polyphase filter.
Generated by jfft.

w_fft The 256-pt fft (or PFB) for the wideband signal path.
Generated by jfft.

sim Behavioral simulation

sim_r gate level simulation

build Build the final chip using separately synthesized modules
from the other directories.

build1 Synthesize and build the chip in 1 go. This takes
a lot of memory, but seems to be a bit faster.
