PHCON(3)						MBK PHYSICAL STRUCTURE DEFINITIONS						  PHCON(3)

NAME

       phcon - mbk physical connector

DESCRIPTION

       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 paralell to its face.

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