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.
