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.
