NAMEcatal - catalog file format
DESCRIPTIONPredefined 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 environment 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 symbolic 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 predefined library, it is possible to virtually remove a cell of a predefined library with the D attribut in the user defined catalog.
