LOCAP(3)	       MBK LOGICAL STRUCTURE DEFINITIONS	      LOCAP(3)

NAME
       locap - mbk logical capacitor

DESCRIPTION
       The  locap  is  used to describe	a logical capacitor. Please note, this
       description is different	from the RCN description and has  a  different
       purpose:	the created capacitor is a functional logical capacitor, not a
       parasitic capacitor.  For the time being, only MIM  (i.e.  metal/metal)
       and POLY/NWELL capacitors type are supported.

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

       The following C structure supports the description of the  logical  ca-
       pacitor :

	      typedef struct locap
		 {
		   struct locap	  *NEXT	;
		   struct locon	  *TCON	;
		   struct locon	  *BCON	;
		   char		  *NAME	;
		   double	  CAPA	;
		   char		  TYPE	;
		   struct ptype	  *USER	;
		 } locap_list		;

       NEXT		   Pointer to the next locap of	the list.

       TCON		   Pointer  to	the  tcon (top plate) connector	of the
			   capacitor. This connector is, of course unique. See
			   locon(3) for	details.

       BCON		   Pointer to the bcon (bottom plate) connector	of the
			   capacitor. This connector is, of course unique. See
			   locon(3) for	details.

       NAME		   Capacitor instance name

       CAPA		   Capacitance value

       TYPE		   Layer  type	of the capacitor. Two legal values are
			   available :

			   CAPMIM	       Metal/metal capacitor. The  top
					       plate  and the bottom plate are
					       in different metal layers.

			   CAPPNWELL	       Poly/NWELL capacitor.  The  top
					       plate layer is POLY, the	bottom
					       plate  layer  is	 NWELL.	 Note:
					       this  capacitor type is techno-
					       logical dependent  and  is  not
					       available for any technology.

       USER		   Pointer  to a ptype list, see ptype(3) for details,
			   that	is a general purpose pointer used to share in-
			   formations  on  the	capacitor.  This field is used
			   with	the LOCAP_INFO(3) ptype	to store physical  in-
			   formations.
