variables in NCTU 307 Lab. workstations
$PATH Variable in Linux
• All binary (i.e. executables) are looked for in the
directories specified in this variable.
• System will search in order, which means if there
are multiple binaries with same filename, the first
match in the $PATH list will be the one being
executed.

$LD_LIBRARY_PATH Variable in Linux
• This variable specifies dynamic linked libraries.
Most programs are too big to be in a single file. So
they may need many external *.so files to be
successfully initiated. (similar to Microsoft
Windows® *.dll)
• The system will also search in order
• Related command : ldd

$LM_LICENSE_FILE Variable in Linux
• The variable used by FlexLM, a license management
services adopted by most EDA tools.
• Refer to CIC website to do the setup:

6. Setup of EDA tools and workstation environment
variables in NCTU 307 Lab. workstations
What’s Xming
• It’s an open-sourced X server for Windows systems
• Some GUI for unix-like systems (Linux, FreeBSD,
Solaris and Mac OS X etc.) are built on X11, which
uses server/client protocol for transmitting graphical
data.
• http://en.wikipedia.org/wiki/X_Window_System

7. Setup of EDA tools and workstation environment
variables in NCTU 307 Lab. workstations
Make sure 3 things first
• Xming is installed.
http://sourceforge.net/projects/xming/
• Extra fonts for xming is installed
• http://sourceforge.net/projects/xming/files/Xming-
fonts/
• Firewall (anti-virus software) is disabled.

$DISPLAY environment variable
• Check whether $DISPLAY is set
– echo $DISPLAY
• Set $DISPLAY in bash shell
– export DISPLAY=140.113.aaa.bbb:0
• Set $DISPLAY in tcsh shell

Debugging License Server Settings
• License won’t check-out
– Check $LM_LICENSE_FILE
and see if the license server
on the previous page exists in
the value (You do not need all
5 to run a single EDA tool)
– Check your research group’s
registration with CIC
– Inform CIC with IP of the
workstation you’re using
• Use their webpage

Simple Debugging Procedures
• Cadence 5.141 won’t start (binary not found)
– Check $PATH variable and see if it contains the path of
“icfb”
– Also check $LD_LIBRARY_PATH
– /usr/cad/cadence/IC/IC51.41.151/tools/bin
– /usr/cad/cadence/IC/IC51.41.151/tools/lib
– Copy .bashrc from /home3/examples/. bashrc to your
home directory for quick solution
