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

                           NTRANS              N transistor

                           PTRANS              P transistor

                           ALU1                first metal

                           ALU2                second metal

                           ALU3                third metal

                           TPOLY               polysilicum through route

                           TALU1               first metal through route

                           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.
