       lofig - mbk logical figure

       The  lofig is used to describe a	hierarchical level of the logical view
       of a figure. The	logical	view is	also called the	netlist, for  list  of
       nets,  because it represents the	interconnections between elements of a

       The declarations	needed to work on lofig	are available  in  the	header
       file "/labo/include/mlo.h".

       The  following C	structure supports the description of the netlist rep-
       resentation :
	      typedef struct lofig {
		 struct	lofig	  *NEXT;
		 struct	chain	  *MODELCHAIN;
		 struct	locon	  *LOCON;
		 struct	losig	  *LOSIG;
		 struct	ptype	  *BKSIG;
		 struct	loins	  *LOINS;
		 struct	lotrs	  *LOTRS;
		 struct	lotrs	  *LOCAP;
		 struct	lotrs	  *LORES;
		 struct	lotrs	  *LOSELF;
		 char		  *NAME;
		 char		  MODE;
		 struct	ptype	  *USER;
	      }	lofig_list;

       NEXT		   Pointer to the next lofig loaded in ram.

       NAME		   Name	of the figure.	It  identifies	a  figure  (or
			   model), so it should	be unique in order to warranty
			   consistency of cells	libraries. In order to	ensure
			   this	 consistency,  the  NAME  field	must be	filled
			   with	the disk file name while parsing, and must  be
			   used	as file	name for driving.

       LOINS		   Pointer  to the head	of the list of instances being
			   used	for the	model description.  See	 loins(3)  for

       LOCON		   Pointer to the head of the list of connectors (ter-
			   minals) of the model.  See locon(3) for details.

       LOSIG		   Pointer to the head of the list of  signal  of  the
			   model.  See losig(3)	for details.

       BKSIG		   Pointer  to	a  hash	 table that contains arrays of
			   LOSIG. It is	only an	other  way  to	represent  the
			   same	elements that in the list, but allows a	faster
			   access. The Mbk Logical Functions warranty the con-
			   sitency between the two representations.

       LOTRS		   Pointer to the list of transistors belonging	to the
			   figure. It is to be noticed	that  transistors  are
			   not instances of a particular type.

       LOCAP		   Pointer  to the list	of capacitors belonging	to the

       LORES		   Pointer to the list of resistors belonging  to  the

       LOSELF		   Pointer  to	the list of inductors belonging	to the

       MODE		   Caracter indicating the status  of  the  figure  in
			   memory. This	field can take two values :

			   'A'	     all the cell is loaded in ram.

			   'P'	     only information concerning the model in-
				     terface is	present,  that	means  connec-
				     tors, and signals linked to external con-
				     nectors.  All other lists are empty.

       MODELCHAIN	   Pointer to a	chain list, see	chain(3) for  details,
			   of  names.  These  are the names of the models that
			   are at least	instanciated once in the figure.

       USER		   Pointer to a	ptype list, see	ptype(3) for  details,
			   that	is a general purpose pointer used to share in-
			   formations on the model.

       mbk(1),	 addlofig(3),	 getlofig(3),	 dellofig(3),	 loadlofig(3),
       savelofig(3),  loins(3),	 lotrs(3),  locap(3), lores(3),	loself(3), lo-
       con(3), losig(3), ptype(3), chain(3), phfig(3).
