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.
