Quick help
----------
The most important file is "impl/virtex4-ml403ep/syn/kotku.v" as is the
top level module for the complete SOC system.

For building the system (Xilinx tools must be installed):
$ source /opt/Xilinx/10.1/ISE/settings64.sh  # (or equivalent)
$ cd impl/virtex4-ml403ep/syn/
$ make

As a result, you will have a file named "kotku.bit", which is the conf-
iguration stream for the FPGA.


Explanation of directories
