#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 vio- lated. 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) SEE ALSO

ADDPHVIA(3) MBK PHYSICAL FUNCTIONS ADDPHVIA(3) NAME
addphvia - create a physical via ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in Paris, France. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.fr SYNOPSYS
#include "mph.h" phvia_list *addphvia(ptfig, viatype, x, y) phfig_list *ptfig; char viatype; long x, y; PARAMETERS
ptfig Pointer to the figure in which the via should be added viatype Contact type x, y Coordinates of the center of the via. DESCRIPTION
addphvia creates a new via whose center is at the given coordinates, and adds it to the list of vias pointed to by ptfig->PHVIA. The new via is added in front of the list, and becomes itself the list head. The parameters viatype, x and y fill respectivly the TYPE, XVIA and YVIA fields of the phvia structure. For a list of valid viatypes, and details on the structure, see phvia(3). RETURN VALUE
addphvia returns a pointer to the newly created via. ERRORS
"*** mbk error *** illegal addphvia viatype : viatype at x, y" The via type is not a predefined contact. For a list of legal via types, see phvia(3). EXAMPLE
#include "mph.h" phvia_list *via_dup(pfd, pfs) /* duplicate vias */ phfig_list *pfd, *pfs; { phvia_list *pv; for (pv = pfs->phvia; pv != NULL; pv = pv->NEXT) addphvia(pfd, pv->TYPE, ps->XVIA, ps->YVIA); return pfd->PHVIA; } SEE ALSO
