phcon.3alc - Man Page

The phcon structure is used to describe a connector belonging to a symbolic layout model, see phfig(3) for details. A strong convention on the mbk data structure is that two connector internally wired have the same name, the 'logical' name.

The declarations needed to work on phcon 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 connector :

typedef struct phcon {
	struct phcon	∗NEXT;
	char	∗NAME;
	long	INDEX;
	long	XCON, YCON;
	long	WIDTH;
	char	ORIENT;
	char	LAYER;
	struct ptype	∗USER;
} phcon_list;

NEXT

Pointer to the next connector of the model.

NAME

Name of the connector. A model may posseses more than one connector with a given name, if they are internally wired.

INDEX

Index of the connector. Since a model may have many connectors with the same name, it is needed to be able to point out one of them. The index allows to distinguish every connector using a topological order. This field is filled by the addphcon function, and shall not be modified otherwise.

XCON, YCON

Connector coordinates. the point (XCON, YCON) must be placed on or inside of the abutment box of the model.

ORIENT

Caracter indicating the face of the model on the which the connector is placed. It may take four values :

NORTH

connector placed on top of cell

SOUTH

connector placed on bottom of cell

EAST

connector placed on right of cell

WEST

connector placed on left of cell

LAYER

Symbolic layer used for the connector. The legal values are :

NWELL

N bulk

PWELL

P bulk

NTIE

N implant in P bulk

PTIE

P implant in N bulk

NDIF

N diffusion

PDIF

P diffusion

NTRANS

N transistor

PTRANS

P transistor

POLY

polysilicium

ALU1

first metal

ALU2

second metal

ALU3

third metal

TPOLY

polysilicum through route

TALU1

first metal through route

TALU2

second metal through route

TALU3

third metal through route

WIDTH

Width of the connector. The physical extension, concerning the width, of a connector is parallel to its face.

USER

Pointer to a ptype list, see ptype for details, that is a general purpose pointer used to share information on the connector.
