#-----------------------------------------------------------------
# File:    xilinx_rules.mk
# Author:  David Burnette
# Date:    April 7, 2008
#
# Description:
#
# Usage:
#  This make file fragment contains translate rules for synthesizing
#  Xilinx designs.
#
# This work was based on the Xilinx Makefile by Dave Vanden Bout
# from XESS Corp. Several major differences exist between his
# implementation and mine. This Makefile does not require PERL
# (though it does require AWK). 
#
# Dependencies:
#  Depends on 'def_rules.mk' fragment.
#
# Revision History:
#   dgb 2008-04-07   Original version
