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;
NEXT
Pointer to the next phvia in the list.
XVIA, YVIA
Coordinates of the center of the via. Vias are macro generated patterns, so only their center is a matter of concern.
TYPE
Via type. The legal types for via are
CONT_POLY
poly alu1 contact
CONT_VIA
alu2 alu1 contact
CONT_DIF_N
alu1 difn contact
CONT_DIF_P
alu1 difp contact
CONT_BODY_N
alu1 nwell contact
CONT_BODY_P
alu1 pwell contact
CONT_VIA2
alu2 alu3 contact
C_X_N
L shaped N transistor corner filling
C_X_P
L shaped P transistor corner filling
USER
Pointer to a ptype list, see ptype(3) for details, that is a general purpose pointer used to share informations on the via.
