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
       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.
