# 2010-05-06 289 1.0 Initial version
#
#
# Add "XON => false," defs in X_FF and X_SFF instances when name of the
# instance is matched by a regexp found in a descriptor file.
#
# Logic:
# looks for lines like
# <name> : X_FF
# generic map(
# and adds
# XON => false, -- added by xilinx_tsim_xon tool --
# if <name> is matched by a regexp found in file stem..tsim_xon_dat
#
# all old 'XON => false' lines in input file are removed first, so this
# tool can be rerun with changing desciptor files.
