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

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();
}
