bigvia - draws a non minimal via as a bunch of vias
See the file man1/alc_origin.1.
void ∗bigvia(figure, viatype, x, y, dx, dy)
long x, y, dx, dy;
- Pointer to the physical figure in the which vias must be put.
- Contact type to be put.
- x, y
- Coordinate of the center of the bigvia.
- dx, dy
- Maximun rectangle to be filled with vias.
draws as many vias as necessary to fill the rectangle defined by
arguments. The ``bigvia'' center is indicated with
, thus making this function much like addphvia
The necessary segments are drawn to avoid having notches or other drc rules
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.
"*** mbk error *** bigvia impossible : negative
values dx, dy in figure figure at (x, y)"
If either dx
are negative, the function complains and exits.
