# File:    xilinx_rules.mk

# Description:
7
#
8
# Usage:
9
#  This make file fragment contains translate rules for synthesizing
10
#  Xilinx designs.
11
#
12
# This work was based on the Xilinx Makefile by Dave Vanden Bout
13
# from XESS Corp. Several major differences exist between his
14
# implementation and mine. This Makefile does not require PERL
15
# (though it does require AWK).
16
#
17
# Dependencies:
18
#  Depends on 'def_rules.mk' fragment.
