Shell Variables

4 Shell Variables

The following shell variables must be set appropriately for the tools to run properly:

Variable Name Use
CDS_INST_DIR Cadence tools installation directory
LM_LICENSE_FILE License files
PATH Directories of the executables
LD_LIBRARY_PATH Tool Shared libraries (if req.)
MANPATH Tool manpages
SNPSLMD_LICENSE_FILE Synopsys license file

Each user can write their own start-up script for initialising all of these variables. Generic shell scripts for doing this are provided with some of the tools. For Cadence and Synopsys these are /vlsi/usr/cds4.43/IC/cshrc and /vlsi/usr/synopsys2000.05/cshrc respectively.
