NAME

       GENLIB_WIRE2 - place two physical segments in the current figure

SYNOPSYS

       #include <genlib.h>
       void GENLIB_WIRE2(layer, width, ins1, con1, index1, ins2, con2, index2, x, y)
       char layer;
       long width;
       char ∗ins1, ∗con1, ∗ins2, ∗con2;
       long x, y;

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

       x, y                Coordinates of the segment's elbow in the current figure

DESCRIPTION

       WIRE2 adds two 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 x, y, and the second one between x, y 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 WIRE2 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_WIRE2 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
              WIRE2 creates segments from relative coordinates, care must be taken to follow the previous rule.
       "GENLIB_WIRE2 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>
       main()
       {
            /∗ Create a figure to work on  ∗/
            GENLIB_DEF_PHFIG("cell");
            GENLIB_PLACE("gaci0_b", "r_addin_1", NOSYM, 0, 0);
            GENLIB_PLACE_TOP("gacin_b", "r_addin_2", NOSYM);
            GENLIB_PLACE_RIGHT("gapgn_b", "pg", NOSYM);
            /∗ Draw a segment ∗/
            GENLIB_WIRE2(ALU1, 1, "r_addin_1", "out", 0L, "pg", "g", 1L,
                      GENLIB_GET_CON_X("pg", "g", 1L),
                      GENLIB_GET_CON_Y("r_addin_1", "out", 0L));
            /∗ Save that on disk ∗/
            GENLIB_SAVE_PHFIG();
       }
