phins - mbk physical instance
The phins structure is used to describe a instance belonging to a symbolic
layout model, see phfig(3)
for details.
The declarations needed to work on phins are available in the header file
/labo/include/mph402.h", where `402' is the actual mbk version.
The following C structure supports the description of the instance :
typedef struct phins {
- struct phins
- *NEXT;
- char
- *INSNAME;
- char
- *FIGNAME;
- long
- XINS,YINS;
- char
- TRANSF;
- struct ptype
- *USER;
} phins_list;
- NEXT
- Pointer to the next instance in the list.
- FIGNAME
- Model of the instance. This gives the name of the figure
that is currently beeing instanciated. The model
may not be present in memory.
- NAME
- Name of the instance. The instance is identified by
its name, so it should be unique at a given hierarchical
level.
- XINS, YINS
- Coordinates of the lower left corner of the instance,
after possible geometrical operation.
- TRANSF
- Contains the geometrical operations that should be
performed before placing the instance. Eight legal
values are allowed :
- NOSYM
- no operation
- SYM_X
- x becomes -x
- SYM_Y
- y becomes -y
- SYMXY
- x becomes -x and y becomes -y
- ROT_P
- rotates 90 degrees counter clockwise
- ROT_M
- rotates 90 degrees clockwise
- SY_RP
- x becomes -x then rotates 90
degrees counter clockwise
- SY_RM
- x becomes -x then rotates 90
degrees clockwise
- USER
- Pointer to a ptype list, see ptype(3)
for details,
that is a general purpose pointer used to share informations
on the instance.
- Remark :
- the phins structure does not contain any information
about the size of the instance. Neither the abutment
box nor the connectors are available. The model must
be loaded when such information is needed.
