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.
