NAME

       GENLIB_DEF_PHINS - define a new reference instance

SYNOPSYS

       #include <genlib.h>
       void GENLIB_DEF_PHINS(instancename);
       char ∗instancename;

PARAMETERS

       instancename        Defines  the  instance  called  instancename  as  the  new  "reference
                           instance"

DESCRIPTION

       DEF_PHINS define the new "reference instance", used as  starting  point  in  the  relative
       placement   functions  of  genlib.  It's  regarding  the  abutment  box  of  the  instance
       instancename that the next instance is going  to  be  placed,  if  using  the  appropriate
       functions.  Notice  that  the  more  recently  placed  instance  becomes  automaticaly the
       "reference instance", if DEF_PHINS isn't called.

ERRORS

       "GENLIB_DEF_PHINS impossible : missing GENLIB_DEF_PHFIG"
              No figure has been yet specified by a call to DEF_PHFIG. So it  isn't  possible  to
              refer  to  an  instance inside it.  you must call DEF_PHFIG before any other layout
              action.
       "instance instancename doesn't exist in current figure"
              The instance instancename hasn't currently been  placed  in  the  figure,  so  it's
              impossible do to any placement from it.

EXAMPLE

       #include <genlib.h>
       main()
       {
            /∗ Create a figure to work on  ∗/
            GENLIB_DEF_PHFIG("cell");
            /∗ Place an instance ∗/
            GENLIB_PLACE("model","i1", NOSYM,0L,0L);
            GENLIB_PLACE("model","i2", NOSYM,120L,40L);
            GENLIB_DEF_PHINS("i1");
            GENLIB_PLACE_TOP("model2", "i3", NOSYM);
            GENLIB_DEF_AB(0, 0, 0, 0);
            /∗ Save all that on disk ∗/
            GENLIB_SAVE_PHFIG();
       }
