NAME

       GENLIB_WIRE3 - place three physical segments in the current figure

SYNOPSYS

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

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);
       }
