GENLIB_PHCON.3(October 1, 1997)		       GENLIB_PHCON.3(October 1, 1997)

NAME
       GENLIB_PHCON  - place a physical	connector in the current figure	at ab-
       solute coordinates

SYNOPSIS
       #include	<genlib.h>
       void GENLIB_PHCON(layer,	width, name, orient, x,	y)
       char layer;
       long width;
       char *name, orient;
       long x, y;

PARAMETERS
       layer		   Layout layer	of the connector

       width		   Width of the	connector

       name		   Name	to be given to the connector

       orient		   Face	of the cell on witch the connector belongs

       x, y		   Absolute coordinates	of the connector

DESCRIPTION
       PHCON adds a connector in the current layout cell, at the specified co-
       ordinates, with the given attributs.  The layer argument	can  take  the
       following legal values:

	      NWELL

	      PWELL

	      NTIE

	      PTIE

	      NDIF

	      PDIF

	      NTRANS

	      PTRANS

	      POLY

	      ALU1

	      ALU2

	      ALU3

	      TPOLY

	      TALU1

	      TALU2

	      TALU3

       The  name  argument  is not enough of an	information to non ambigiously
       identify	a connector.  In order to be able to do	so, an index  is  com-
       puted for each connector	that has an already existing name, following a
       topological  order.  Each time a	connector is created, the index	is up-
       dated, regarding	the name of the	connector.  Since  someone  writing  a
       tiler  needs  to	 know exactly what connector to	access,	the indexation
       algorithm must be known by the user.

       Connectors with a unique	name:
			   Such	connectors have	the index 0

       Connectors with a name apearing many times:
			   The indexes are computed from left  to  right,  and
			   then	 from  bottom  to  top,	starting at 0.	If two
			   connectors are on the same location,	with the  same
			   name,  then	the layer decides which	one is has the
			   greater number, from	lower level,  NWELL  to	 upper
			   level, ALU3.

       The orient parameter may	take the following values:

       NORTH		   for a connector placed on the top of	the cell.

       SOUTH		   for a connector placed on the bottom	of the cell.

       EAST		   for	a  connector  placed  on the right side	of the
			   cell.

       WEST		   for a connector placed on  the  left	 side  of  the
			   cell.

       Remark:		   Connectors  placed  on  corners  of	leaf cells are
			   given the EAST orientation if on top/right or  bot-
			   tom/right  corner,  and  WEST  if  top/left or bot-
			   tom/left.

ERRORS
       "GENLIB_PHCON impossible	: missing GENLIB_DEF_PHFIG"
	      No figure	has been yet specified by a call to DEF_PHFIG.	So  it
	      isn't  possible  to  place a connector inside it.	 you must call
	      DEF_PHFIG	before any other layout	action.
       "illegal	addphcon : orientation is XX in	name"
	      The orient parameter does	not have a legal value,	but XX.

EXAMPLE
       #include	<genlib.h>
       main()
       {
	    /* Create a	figure to work on  */
	    GENLIB_DEF_PHFIG("cell");
	    .
	    .
	    .
	    GENLIB_DEF_AB(0L, 0L, 0L, 0L);
	    /* Put a connector */
	    GENLIB_PHCON(ALU1, 1, "cin", SOUTH,	12L, 0L);
	    /* Save that on disk */
	    GENLIB_SAVE_PHFIG();
       }
