NAME

       GENLIB_DEF_AB - define a new abutment box to the current layout cell

SYNOPSYS

       #include <genlib.h>
       void GENLIB_DEF_AB(dx1, dy1, dx2, dy2);
       long dx1, dy1, dx2, dy2;

PARAMETERS

       dx1, dy1            Values to be added to the lower left corner of the previous abutment box

       dx2, dy2            Values to be added to the upper right corner of the previous abutment box

DESCRIPTION

       DEF_AB give a new abutment box to the current physical cell.  The coordinates of the abutment box are the
       coordinates of the envelop of the abutment boxes  of  each  instance  plus  the  delta  values  given  as
       argument.  The  (dx1,  dy1) values are added to the (x1, y1) coordinates of the bottom left corner of the
       "standard abutment box" (the envelop), and the (dx2, dy2) are added to the top right ones.  You  have  to
       call  this  function  before  saving,  otherwise  the  figure  will  not have an abutment box. Since it's
       regarding the abutment box of its model that an instance is placed, any futher use of this figure will be
       incorrect if DEF_AB isn't called, or properly defined.

ERRORS

       "GENLIB_DEF_AB impossible : missing GENLIB_DEF_PHFIG"
              No  figure  has been yet specified by a call to DEF_PHFIG. So it isn't possible to give it a size.
              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");
            /∗ 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);
            /∗ define the new abutment box as the standard envelop ∗/
            GENLIB_DEF_AB(0, 0, 0, 0);
            /∗ Save all that on disk ∗/
            GENLIB_SAVE_PHFIG();
       }
