# If you don't want to print all fields, change the @print_order
# declaration below.
# 
# Note that the figures will usually not be exactly the same as the
# figures reported by map. This is partly because map does not count a 
# LUT with a constant output as a LUT, at least not in ISE 8.1.
#
# The program will also automatically convert a .ncd-file to a temporary
# .xdl file before running.
#
# This program has been tested on designs targetted at Virtex-2 and
# Virtex-4 from ISE 8.1 and ISE 8.2 on a Linux based computer. Note
# that it assumes that your path separator is set to /.
#
# Missing features:
#   * Slice count would be nice
#   * Show number of LUTs used as distributed RAM and SRL16
#   * Virtex-5 support
#
# NOTE:
#   The synthesizer will probably optimize your design across module boundaries
#   in some cases. This means that your figures cannot be entirely correct.
