SYNOPSYS

       #include "mut.h"
       int incatalogfeed(figname)
       char *figname;

PARAMETER

       figname		   Name of the cell to be checked

DESCRIPTION

       incatalogfeed checks a cell represented by its figname beeing present in the catalog file with the 'F' attribut.  This means that the  cell
       is a feed through, and does not have a logical equivalent representation while beeing physicaly used.
       This information is mostly needed by routers, since "logical feed through" has no design meaning.
       The  catalog  is  the sum of all the catalogs of the cells libraries specified in the MBK_CATA_LIB(1) and MBK_WORK_LIB(1).  The catalogs of
       the MBK_CATA_LIB(1) are the files called CATAL, and the MBK_WORK_LIB(1) is by default CATAL but can be changed to MBK_CATAL_NAME(1).

RETURN VALUE

       incatalogfeed returns 0 if the cell does not belong to the catalog with the 'F' attribut, a value different from 0 if it does.

EXAMPLE

       #include "mut.h"
       char *tell_if_incatalogfeed(name)
       char *name;
       {
	  return incatalogfeed(name) ? "Jawohl, mein Herr" : "Nein, danke";
       }

DESCRIPTION

       Predefined libraries
              The environment variable MBK_CATA_LIB(1) defines several paths corresponding  to  the  Alliance  predefined  cell  libraries.   Each
              library is in one unix directory.

              sxlib               standard cell library

              dp_sxlib            data-path compiler library

              rflib               registers library

              ramlib              ram library

              romlib              rom library

              padlib              pads lib

              For each library, a special file named CATAL describes the library
                                  contents.   This  file  must  be  in the same directory as the library cells.  For the Alliance tools, the cells
                                  described in the predefined libraries are read only.

       The working library
              The environment variable MBK_WORK_LIB(1) defines the current working directory.  Its default value is . (dot).  This directory  will
              contain  the  user cells, seen as read write by the Alliance tools.  It is not necessary to describe all the user cells in a catalog
              file.  But the user can locally define a catalog file for the working library.  The local catalog file name is set by  the  environ-
              ment  variable MBK_CATAL_NAME(1), CATAL by default.  Alliance will concatenate all catalog files of the predefined libraries and the
              optional catalog file of the working library to access the attributs of each cell.

       Cells attributs
              A cell may be characterized by four attributs:

              C                   this attribut means that the cell is a leaf cell in the context of a recursive flatten, for either the layout or
                                  netlist view.  The cell will not be flattened.

              G                   this  attribut means that the cell has an existing equivalent GDS or CIF representation.  It is used by the sym-
                                  bolic to real translation tool, s2r(1), to make direct replacements.

              F                   this attribut means that the cell is used as a feed through.

              D                   this attribut is used only in the user defined catalog.  As the user is not allowed to delete a cell in a prede-
                                  fined library, it is possible to virtually remove a cell of a predefined library with the D attribut in the user
                                  defined catalog.
