SYNOPSYS¶
#include "mph.h"
void ∗bigvia(figure, viatype, x, y, dx, dy)
phfig_list ∗figure;
char viatype;
long x, y, dx, dy;
PARAMETERS¶
- figure
- Pointer to the physical figure in the which vias must be put.
- viatype
- Contact type to be put.
- x, y
- Coordinate of the center of the bigvia.
- dx, dy
- Maximun rectangle to be filled with vias.
DESCRIPTION¶
bigvia draws as many vias as necessary to fill the rectangle defined by
its
dx and
dy arguments. The ``bigvia'' center is indicated with
dx and
dy, thus making this function much like
addphvia.
The necessary segments are drawn to avoid having notches or other drc rules
violated.
This function is tipically used by routers when connecting two non minimal
wires, like supplies or clocks.
The values for drawing the via correctly, ie avoid drc violations, are taken
from the idps set of rules, and are not changeable at run time.
ERRORS¶
"*** mbk error *** bigvia impossible : negative
values dx, dy in figure figure at (x, y)"
If either
dx or
dy are negative, the function complains and exits.
EXAMPLE¶
#include "mph.h"
#define BigVia(x, y, dx, dy) \
bigvia(WORK_PHFIG, CONT_VIA, x, y, dx, dy)
