NAME
locon - mbk logical connector
DESCRIPTION
The locon is used to describe a connector of the logical view of a figure. Connectors are describing
the cell interface, and are the link between its physical and logical views, so the names must be the
same.
The declarations needed to work on locon are available in the header file "/labo/include/mlo404.h", where
'404' is the actual mbk version.
The following C structure supports the description of the logical connector :
typedef struct locon {
struct locon ∗NEXT;
char ∗NAME;
struct losig ∗SIG;
void ∗ROOT;
char DIRECTION;
char TYPE;
struct ptype ∗USER;
} locon_list;
NEXT Pointer to the next locon of the list.
NAME Name of the connector. It identifies the connector, so it should unique in a given
logical figure. A logical connector with a given name correspond to the physical
connector or connectors of this name.
SIG Pointer to the signal linked to the connector. This signal is, of course, unique. See
losig(3) for details.
ROOT Pointer to the object it belongs to. This object may be either a lofig, or a loins,
depending on the type of the connector. See lofig(3) and loins for details.
DIRECTION This indicates the way of the information going through the connector. Six
directions are legal :
IN input
OUT output
INOUT input and output
UNKNOWN no information is available
TRISTATE tristate output
TRANSCV tristate output and input
TYPE Character indicating if the connector belongs to a model or an instance. It can take
two values :
EXTERNAL for figure connectors
INTERNAL for instance connectors
The TYPE is needed to appropriatly cast the ROOT field, and must be approriatly
filled by the parsers. A misuse of it may cause strange behaviours.
USER Pointer to a ptype list, see ptype for details, that is a general purpose pointer
used to share informations on the connector.
