PHREF(3)	      MBK PHYSICAL STRUCTURE DEFINITIONS	      PHREF(3)

NAME
       phref - mbk physical reference

DESCRIPTION
       The phref structure is used to describe a reference belonging to	a sym-
       bolic layout model, see phfig(3)	for details.  A	 reference  allows  to
       name  a point anywhere in a given model.	It may then be seen as a name,
       and not anymore as a couple of coordinates.  References are mostly used
       for cell	programming and	multi-access connector representation.

       The  declarations  needed  to work on phref are available in the	header
       file "/labo/include/mph402.h", where '402' is the actual	mbk version.

       The following C structure supports the description of the reference :
	      typedef struct phref {
		 struct	phref	  *NEXT;
		 char		  *FIGNAME;
		 char		  *NAME;
		 long		  XREF,YREF;
		 struct	ptype	  *USER;
	      }	phref_list;

       NEXT		   Pointer to the next reference in the	list.

       FIGNAME		   Kind	of reference. Gives information	about the pos-
			   sible  uses of the object.  Some FIGNAME are	in use
			   today :

			   "ref_con"	       for multi-access	connectors

			   "ref_ref"	       for all other uses

       NAME		   Name	of the reference. The refence is identified by
			   its name, so	it should be unique at a given hierar-
			   chical level.

       XREF, YREF	   Coordinates of the point beeing referenced.

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