BIGVIA(3)		MBK PHYSICAL UTILITY FUNCTIONS		     BIGVIA(3)

NAME
       bigvia -	draws a	non minimal via	as a bunch of vias

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 min-
       imal 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)

SEE ALSO
       mbk(1), addphvia(3), addphseg(3).
