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 capacitor :

	      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 technological 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 informations on  the
			   capacitor.  This field is used with the LOCAP_INFO(3) ptype to store physical informations.
