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.
