MBK_CATA_LIB(1)                                              MBK ENVIRONMENT VARIABLES                                             MBK_CATA_LIB(1)

NAME
MBK_CATA_LIB - define the mbk catalog directory SYNOPSYS
c-shell running setenv MBK_CATA_LIB path1:path2:path3:...:...:pathn ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in Paris, France. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.fr DESCRIPTION
MBK_CATA_LIB sets the directories that are to be searched thru for reading. When instanciating a cell for example, the first cell that is found with the given name is loaded in memory. The seaching mecanism first look in MBK_WORK_LIB(1), and then, in path1 thru pathn, in the order defined by the user when typing the setenv command. This directories are considered to be, from a mbk point of view, read only. The pathi arguments must be actually accessible pathes on your host machine. ERRORS
"mbk_fopen : can't open file 'unix_path/file.xx' thru directories : path1, ..., pathn" This occurs when either the unix path is irrelevent, or when the file doesn't exist. This can also be a unix right problem if the file is not accessible for reading, but this is seldom. EXAMPLE
setenv MBK_CATA_LIB ~fred/crechan/uom:/labo/sclib DIAGNOSTICS
Only the first path may be given with a '~', since the shell extents it only when seen first. SEE ALSO
mbk(3), genlib(1), MBK_WORK_LIB(1). BUG REPORT
This tool is under development at the ASIM department of the LIP6 laboratory. We need your feedback to improve documentation and tools. ASIM
