       phfig - mbk physical figure


       The  phfig  is  used to describe a hierarchical level of a symbolic layout and may contain
       any of the legal physical objects needed for a layout but a phfig.   All  coordinates  are
       symbolic and therefor put on a virtual grid in booth x and y directions.

       The   declarations   needed   to   work   on  phfig  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 layout view :
              typedef struct phfig {
                 struct phfig     ∗NEXT;
                 struct chain     ∗MODELCHAIN;
                 struct phseg     ∗PHSEG;
                 struct phvia     ∗PHVIA;
                 struct phref     ∗PHREF;
                 struct phins     ∗PHINS;
                 struct phcon     ∗PHCON;
                 char             ∗NAME;
                 char             MODE;
                 long             XAB1, YAB1, XAB2, YAB2;
                 struct ptype     ∗USER;
              } phfig_list;

       NEXT                Pointer to the next phfig present in ram.

       NAME                Name of the figure. It identifies a figure (or model), so it should be
                           unique  in  order to warranty consistency of cells libraries. In order
                           to ensure this consistency, the NAME field must  be  filled  with  the
                           disk  file  name  while  parsing,  and  must  be used as file name for

       PHINS               Pointer to the head of the list of instances being used for the  model
                           description. See phins(3) for details.

       PHCON               Pointer  to  the  head  of  the  list of connectors (terminals) of the
                           model.  See phcon(3) for details.

       PHSEG               Pointer to the head of the list of segments (wires) of the model.  See
                           phseg(3) for details.

       PHVIA               Pointer to the head of the list of contacs and vias of the model.  See
                           phvia(3) for details.

       PHREF               Pointer to the head of the list  of  references  of  the  model.   See
                           phref(3) for details.

       XAB1, YAB1, XAB2, YAB2
                           Coordinates  of  the  bottom  left  corner  of the abutment box of the
                           figure. The abutment box of a model represents the external visibility
                           of  a  figure  and is what reference is made to when instanciating the
                           model.  One should well distinguish the abutment box from the bounding
                           box,   which   is  the  smallest  rectangle  that  includes  all  cell
                           descriptors.  The size and position of the abutment box is a  designer
                           concern, and cannot be computed.

       MODE                Caracter indicating the status of the figure in memory. This field can
                           take two values :

                           ´A´       all the cell is loaded in ram.

                           ´P´       only information concerning the model interface is  present,
                                     that  means connectors and the abutment box. All other lists
                                     are empty.

       MODELCHAIN          Pointer to a chain list, see chain(3) for details, of names. These are
                           the  names  of  the  models that are at least instanciated once in the

       USER                Pointer to a ptype list, see ptype(3) for details, that is  a  general
                           purpose pointer used to share informations on the model.

       Remark :            mbk's physical view of a cell is releted to it's logical view by means
                           of connector names, that must be identical.
