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.
