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;

ORIGIN

       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

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();
       }
