NAME

       GENLIB_PLACE_VIA_REF  -  put  a  via on top of a reference belonging to an instance in the
       current figure

SYNOPSYS

       #include <genlib.h>
       void GENLIB_PLACE_VIA_REF(insname, refname, viatype)
       char  ∗insname, ∗refname;
       char viatype;

PARAMETERS

       insname             Name of the instance in the which the reference is to be searched for

       refname             Name of the reference to be used as target point

       viatype             Type of via to be placed

DESCRIPTION

       PLACE_VIA_REF places a via of type viatype on top of the specified reference, refname,  in
       the  instance  called  insname.   This  function may be used to generate many cells from a
       single  one,  in  order  to  "program"  decoders  for  example,  or  in  conjuction   with
       PLACE_SEG_REF(3) or PLACE_CON_REF(3) to translate virtual connectors into fixed ones.
       The viatype argument may take the following legal values:

       CONT_POLY           links POLY and ALU1

       CONT_DIF_N          links NDIF and ALU1

       CONT_DIF_P          links PDIF and ALU1

       CONT_BODY_N         links NTIE and ALU1

       CONT_BODY_P         links PTIE and ALU1

       CONT_VIA            links ALU1 and ALU2

       CONT_VIA2           links ALU2 and ALU3

ERRORS

       "GENLIB_PLACE_VIA_REF 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.
       "illegal getphins : instance insname does not exist"
              The instance called insname does not currently belong to the figure.
       "illegal getphref : references called refname does not exist"
              No reference called refname exists in the model of the instance insname.

EXAMPLE

       #include <genlib.h>
       main()
       {
            /∗ Create a figure to work on  ∗/
            GENLIB_DEF_PHFIG("cell");
            GENLIB_PLACE("gaci0_b", "r1", NOSYM, 23L, 54L);
            /∗ Put a reference ∗/
            GENLIB_PLACE_VIA_REF("a_0", "r1", CONT_VIA);
            /∗ Save that on disk ∗/
            GENLIB_SAVE_PHFIG();
       }
