SYNOPSYS

       #include <genlib.h>
       void GENLIB_WIRE3(layer, width, ins1, con1, index1, ins2, con2, index2, x1, y1, x2, y2)
       char layer;

PARAMETERS

       layer		   Layout layer of the segment

       width		   Width of the segment

       ins1		   Name of the instance in which the connector con1 is to be looked for

       con1		   Name of a connector, or reference, used as first endpoint of the wire

       ins2		   Name of the instance in which the connector con2 is to be looked for

       con2		   Name of a connector, or reference, used as last endpoint of the wire

       x1, y1		   Coordinates of the segment's first elbow endpoint in the current figure

       x2, y2		   Coordinates of the segment's second elbow endpoint in the current figure

DESCRIPTION

       WIRE3 adds three segments made of the layer level in the current layout cell, the starting point beeing the connector, or  reference,  con1
       of  the	instance  ins1,  and  the  ending  point beeing the connector, or reference, con2 of the instance ins1. The first segment is drawn
       between the coordinates of con1 in the current figure and x1, y1. The second one between x1, y1 and x2, y2,  and  the  last,  but  not  the
       least, between x2, y2 and the coordinates of con2 in the current figure.

       If  the endpoints are connectors, the indexes index1 and index2 must respectivly refer to con1 and con2.  If they are references, then they
       are not taked care of.  One shall notice that connectors and references of a given model should not share names if WIRE3 is to be used.

       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

ERRORS

       "GENLIB_WIRE3 impossible : missing GENLIB_DEF_PHFIG"
	      No figure has been yet specified by a call to DEF_PHFIG. So it isn't possible to	place  an  instance  inside  it.   you	must  call
	      DEF_PHFIG before any other layout action.
       "illegal addphseg : x1, y1, x2, y2"
	      A  symbolic segment must be either vertical or horizontal, so either x1 = x2, or y1 = y2. Since WIRE3 creates segments from relative
	      coordinates, care must be taken to follow the previous rule.
       "GENLIB_WIRE3 impossible : same name conX, for connector and reference in insX"
	      The model of the instance insX has both a connector and a reference that matches the conX name.  This  is  not  legal  since  genlib
	      doesn't know which one to choose as point.
       "illegal getphins : instance insX does not exist"
	      The instance called insX does not currently belong to the figure.

EXAMPLE

       #include <genlib.h>
       draw_wire(cellHeight)
       long cellHeight;
       {
	    /* draw a wire made of 1, 2, or 3 segments, given from and to connectors
	       or reference, and the x and y coordinates of each elbow points */
	    GENLIB_WIRE1(ALU1,1,"lastpg2","g2",1,"cabl31","sg",2);
	    GENLIB_WIRE3(ALU1,1,"cabl31","sp",2, "celout2", "cin", 1,
		      GENLIB_GET_CON_X("cabl31","sp",2),
		      GENLIB_GET_CON_Y("cabl31","sp",2) + cellHeight / 2,
		      GENLIB_GET_CON_X("celout2", "cin", 1),
		      GENLIB_GET_CON_Y("cabl31","sp",2) + cellHeight / 2);
	    GENLIB_WIRE1(POLY,1,"celout3","g",1,"celout2","co",0);
       }
