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 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.
