This directory contains a number of scripts to manage digital hierarchies. 

lgftodef -  diglog wrapper to produce a *.def file from a *.lgf file.
lgftontk - diglog wrapper to produce a *.ntk file from a *.lgf file.
lgfextract - diglog wrapper to perform extraction upon a *.lgf file.
logar - loged wrapper to update a gate's definition.
makeinstcopy - loged wrapper to make an inst copy of a gate.

These wrapper scripts can be used from within a Makefile to automate
the build process of digital hierarchies.

A Makefile would contain the following SUFFIX and build rule:-
#----------------------------------------------------------------------------
.SUFFIXES: .lgf .def
.lgf.def:
	# makeinstcopy $(GATELIB) $@
	lgftodef $<
	logar $(GATEFILE) $@
#----------------------------------------------------------------------------

The makeinstcopy line is used to recreate a custom instance counterpart
from a native digital gate.
