NAME

       phcon - mbk physical connector

DESCRIPTION

       The  phcon structure is used to describe a connector belonging to a symbolic layout model,
       see phfig(3) for details. A strong convention on  the  mbk  data  structure  is  that  two
       connector internally wired have the same name, the 'logical' name.

       The   declarations   needed   to   work   on  phcon  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 connector :
              typedef struct phcon {
                 struct phcon     ∗NEXT;
                 char             ∗NAME;
                 long             INDEX;
                 long             XCON, YCON;
                 long             WIDTH;
                 char             ORIENT;
                 char             LAYER;
                 struct ptype     ∗USER;
              } phcon_list;

       NEXT                Pointer to the next connector of the model.

       NAME                Name of the connector. A model may posseses more  than  one  connector
                           with a given name, if they are internally wired.

       INDEX               Index  of  the  connector. Since a model may have many connectors with
                           the same name, it is needed to be able to point out one of  them.  The
                           index allows to distinguish every connector using a topological order.
                           This field is filled by  the  addphcon  function,  and  shall  not  be
                           modified otherwise.

       XCON, YCON          Connector  coordinates.  the  point  (XCON, YCON) must be placed on or
                           inside of the abutment box of the model.

       ORIENT              Caracter indicating the face of the model on the which  the  connector
                           is placed.  It may take four values :

                           NORTH               connector placed on top of cell

                           SOUTH               connector placed on bottom of cell

                           EAST                connector placed on right of cell

                           WEST                connector placed on left of cell

       LAYER               Symbolic layer used for the connector. The legal values are :

                           NWELL               N bulk

                           PWELL               P bulk

                           NTIE                N implant in P bulk

                           PTIE                P implant in N bulk

                           NDIF                N diffusion

                           PDIF                P diffusion

                           PTRANS              P transistor

                           ALU2                second metal

                           ALU3                third metal

                           TALU2               second metal through route

                           TALU3               third metal through route

       WIDTH               Width  of the connector. The physical extension, concerning the width,
                           of a connector is paralell to its face.

       USER                Pointer to a ptype list, see ptype for  details,  that  is  a  general
                           purpose pointer used to share informations on the connector.
