NAME
phfig - mbk physical figure
DESCRIPTION
The phfig is used to describe a hierarchical level of a symbolic layout and may contain any of the legal
physical objects needed for a layout but a phfig. All coordinates are symbolic and therefor put on a
virtual grid in booth x and y directions.
The declarations needed to work on phfig 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 layout view :
typedef struct phfig {
struct phfig ∗NEXT;
struct chain ∗MODELCHAIN;
struct phseg ∗PHSEG;
struct phvia ∗PHVIA;
struct phref ∗PHREF;
struct phins ∗PHINS;
struct phcon ∗PHCON;
char ∗NAME;
char MODE;
long XAB1, YAB1, XAB2, YAB2;
struct ptype ∗USER;
} phfig_list;
NEXT Pointer to the next phfig present in ram.
NAME Name of the figure. It identifies a figure (or model), so it should be unique in
order to warranty consistency of cells libraries. In order to ensure this
consistency, the NAME field must be filled with the disk file name while parsing, and
must be used as file name for driving.
PHINS Pointer to the head of the list of instances being used for the model description.
See phins(3) for details.
PHCON Pointer to the head of the list of connectors (terminals) of the model. See phcon(3)
for details.
PHSEG Pointer to the head of the list of segments (wires) of the model. See phseg(3) for
details.
PHVIA Pointer to the head of the list of contacs and vias of the model. See phvia(3) for
details.
PHREF Pointer to the head of the list of references of the model. See phref(3) for
details.
XAB1, YAB1, XAB2, YAB2
Coordinates of the bottom left corner of the abutment box of the figure. The abutment
box of a model represents the external visibility of a figure and is what reference
is made to when instanciating the model. One should well distinguish the abutment
box from the bounding box, which is the smallest rectangle that includes all cell
descriptors. The size and position of the abutment box is a designer concern, and
cannot be computed.
MODE Caracter indicating the status of the figure in memory. This field can take two
values :
´A´ all the cell is loaded in ram.
´P´ only information concerning the model interface is present, that means
connectors and the abutment box. All other lists are empty.
MODELCHAIN Pointer to a chain list, see chain(3) for details, of names. These are the names of
the models that are at least instanciated once in the figure.
USER Pointer to a ptype list, see ptype(3) for details, that is a general purpose pointer
used to share informations on the model.
Remark : mbk's physical view of a cell is releted to it's logical view by means of connector
names, that must be identical.
