NAME

       GENLIB_PHREF - place a physical reference in the current figure at absolute coordinates

SYNOPSYS

       #include <genlib.h>
       void GENLIB_PHREF(type, name, x, y)
       char ∗type, ∗name;
       long x, y;

PARAMETERS

       type                Type of the reference to be added

       name                Name of the reference

       x, y                Absolute coordinates of the reference

DESCRIPTION

       PHREF  adds  a  reference  in  the  current  layout cell, at the specified coordinates.  A
       reference is an object that allows to symbolicaly name  a  point  for  futur  use  by  the
       designer.   They have been mainly used in the past to program decoders, in order to obtain
       many cells from a unique cell.

       The type argument may take the two following legal values:

       ref_con             for virtual connectors, see dpr(1) for details.

       ref_ref             for any other need from the designer.

ERRORS

       "GENLIB_PHREF 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  reference  inside  it.   you  must call DEF_PHFIG before any other layout
              action.

EXAMPLE

       #include <genlib.h>
       main()
       {
            /∗ Create a figure to work on  ∗/
            GENLIB_DEF_PHFIG("cell");
            .
            /∗ Put a reference ∗/
            GENLIB_PHREF("ref_con", "in_a[0]", 102L, 10L);
            .
            .
            GENLIB_DEF_AB(0L, 0L, 0L, 0L);
            /∗ Save that on disk ∗/
            GENLIB_SAVE_PHFIG();
       }
