PHVIA(3) MBK PHYSICAL STRUCTURE DEFINITIONS PHVIA(3)

NAME

phvia - mbk physical contact

DESCRIPTION

The phvia structure is used to describe a via or contact belonging to a symbolic layout model, see phfig(3) for details.

The declarations needed to work on phvia are available in the header file "/labo/include/mph402.h", where '402' is the actual mbk version.

The following C structure supports the description of the via :

typedef struct phvia {
	struct phvia	∗NEXT;
	char	TYPE;
	long	XVIA,YVIA;
	struct ptype	∗USER;
} phvia_list;
Pointer to the next phvia in the list.
Coordinates of the center of the via. Vias are macro generated patterns, so only their center is a matter of concern.
Via type. The legal types for via are
poly alu1 contact
alu2 alu1 contact
alu1 difn contact
alu1 difp contact
alu1 nwell contact
alu1 pwell contact
alu2 alu3 contact
L shaped N transistor corner filling
L shaped P transistor corner filling
Pointer to a ptype list, see ptype(3) for details, that is a general purpose pointer used to share informations on the via.
