NAME

6       bigvia - draws a non minimal via as a bunch of vias
7

SYNOPSIS

9       #include "mph.h"
10       void ∗bigvia(figure, viatype, x, y, dx, dy)
11       phfig_list ∗figure;
12       char viatype;
13       long x, y, dx, dy;
14

PARAMETERS

16       figure              Pointer  to  the  physical figure in the which vias
17                           must be put.
18
19       viatype             Contact type to be put.
20
21       x, y                Coordinate of the center of the bigvia.
22
23       dx, dy              Maximun rectangle to be filled with vias.
24

DESCRIPTION

26       bigvia draws as many vias as necessary to fill the rectangle defined by
27       its  dx  and  dy arguments.  The ``bigvia'' center is indicated with dx
28       and dy, thus making this function much like  addphvia.   The  necessary
29       segments are drawn to avoid having notches or other drc rules violated.
30       This function is tipically used by routers when connecting two non min‐
31       imal wires, like supplies or clocks.
32       The values for drawing the via correctly, ie avoid drc violations,  are
33       taken from the idps set of rules, and are not changeable at run time.
34

ERRORS

36              "*** mbk error *** bigvia impossible : negative values dx, dy in
37              figure figure at (x, y)"
38       If either dx or dy are negative, the function complains and exits.
39

EXAMPLE

42       #define BigVia(x, y, dx, dy) \
43          bigvia(WORK_PHFIG, CONT_VIA, x, y, dx, dy)
