BIGVIA(3) MBK PHYSICAL UTILITY FUNCTIONS BIGVIA(3)
NAME
bigvia - draws a non minimal via as a bunch of vias
ORIGIN
This software belongs to the *ALLIANCE CAD SYSTEM *developed by the ASIM
team at **LIP6 **laboratory of UniversitÃ© Pierre et Marie CURIE, in Paris,
France.

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)**
