LOSIG(3)						 MBK LOGICAL STRUCTURE DEFINITIONS						  LOSIG(3)

NAME

       losig - mbk logical signal

DESCRIPTION

       The losig is used to describe a logical signal.

       The declarations needed to work on losig are available in the header file "/labo/include/mlo404.h", where '404' is the actual mbk version.

       The following C structure supports the description of the logical signal :
	      typedef struct losig {
		 struct losig	  *NEXT;
		 struct chain	  *NAMECHAIN;
		 float		  CAPA;
		 long		  INDEX;
		 char		  TYPE;
		 struct ptype	  *USER;
	      } losig_list;

       NEXT		   Pointer to the next losig of the list.

       INDEX		   Long  integer  beeing  the  signal  identifier.  It represents the net number at a given hierachical level, and must be
			   unique.

       NAMECHAIN	   Pointer to a list of names, aliases, attached to the signal. If no names are given then the field points to NULL.  Many
			   names can be present if the signal result of the flatten of a netlist.  See chain(3) for details.

       CAPA		   Floating  point  number  containing	the value of the total capacitance attached to a signal in respect to ground. This
			   field may be set to zero, since it make sens only if the signal is the result of a layout extraction, or has been  used
			   for electrical simulation purposes.

       TYPE		   This field can take two legal values depending on the types of the connectors attached to it. See locon(3) for detail.

			   EXTERNAL	       The  signal  is	connected  at  least  to  one external connector, a connector of the figure beeing
					       described.

			   INTERNAL	       The signal is connected only to instances or transistors connectors.

			   The tools using the TYPE should fill it with care, since unexpected results may appear if the consistency with  connec-
			   tors is violated.

       USER		   Pointer  to a ptype list, see ptype(3) for details, that is a general purpose pointer used to share informations on the
			   signal.

       Remark : 	   the netlist view is given in terms of connectors pointing to signals, but it may be useful to have also the dual repre-
			   sentation, in term of list of connectors attached to a single signal. This may be obtained by the lofigchain function.

NAME

       locon - mbk logical connector

DESCRIPTION

       The  locon  is  used to describe a connector of the logical view     of a figure. Connectors are describing the cell interface, and are the
       link between its physical and logical views, so the names must be the same.

       The declarations needed to work on locon are available in the header file "/labo/include/mlo404.h", where '404' is the actual mbk version.

       The following C structure supports the description of the logical connector :
	      typedef struct locon {
		 struct locon	  *NEXT;
		 char		  *NAME;
		 struct losig	  *SIG;
		 void		  *ROOT;
		 char		  DIRECTION;
		 char		  TYPE;
		 struct ptype	  *USER;
	      } locon_list;

       NEXT		   Pointer to the next locon of the list.

       NAME		   Name of the connector. It identifies the connector, so it should unique in a given logical figure. A logical  connector
			   with a given name correspond to the physical connector or connectors of this name.

       SIG		   Pointer to the signal linked to the connector. This signal is, of course, unique. See losig(3) for details.

       ROOT		   Pointer  to	the object it belongs to. This object may be either a lofig, or a loins, depending on the type of the con-
			   nector.  See lofig(3) and loins for details.

       DIRECTION	   This indicates the way of the information going through the connector.  Six directions are legal :

			   IN		       input

			   OUT		       output

			   INOUT	       input and output

			   UNKNOWN	       no information is available

			   TRISTATE	       tristate output

			   TRANSCV	       tristate output and input

       TYPE		   Character indicating if the connector belongs to a model or an instance. It can take two values :

			   EXTERNAL	       for figure connectors

			   INTERNAL	       for instance connectors

			   The TYPE is needed to appropriatly cast the ROOT field, and must be approriatly filled by the parsers. A misuse  of	it
			   may cause strange behaviours.

       USER		   Pointer  to	a  ptype  list, see ptype for details, that is a general purpose pointer used to share informations on the
			   connector.
