$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: http://www.cic.edu.tw– Synopsis: 26585@lsnctu

– Springsoft Verdi (now Synopsis): 5219@lsnctu

– Springsoft Laker (now Synopsis): 5229@lsnctu

– Mentor Graphics: 1717@lsnctu3

– Cadence: 5280@lsnctu

• Related command: lmstat –a -c

$DISPLAY Variable in Linux

• export DISPLAY=<YOUR_IP_ADDRESS>:0

• Open-source X11 server: Xming

http://sourceforge.net/projects/xming

2012/7/18 5

http://sourceforge.net/projects/xming


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

Xming setup for RFVLSI62014/4/18

http://en.wikipedia.org/wiki/X_Window_System


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.


http://sourceforge.net/projects/xming/

http://sourceforge.net/projects/xming/files/Xming-fonts/


Just click next, next, and next…

• After Xming is installed, please configure Xlaunch



Configure XLaunch



Configure Xlaunch (continued)

Check “No Access Control”



Configure Xlaunch (continued)

Save configuration to desktop



How/When to start Xming?

• Click the desktop icon you saved

• Start xming before staring any GUI on

workstation



$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

– setenv DISPLAY 140.113.aaa.bbb:0



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

2012/7/18 15



• Cadence 5.141 won’t start and you see the

following message: Contact system administrator*WARNING* voInit failed to find the passwd entry for (null), using '/tmp' for a home directory.The most likely cause of this problem is the failure of NIS lookups.Please contact your system administrator.*WARNING* clsInit failed: Success*WARNING* file /.../…/CDS.log Success*WARNING* file /.../.../CDS.log.1 Success*WARNING* file /.../.../CDS.log.2 Success*WARNING* file /.../.../CDS.log.3 Success*WARNING* file /.../.../CDS.log.4 Success*WARNING* file /.../.../CDS.log.5 Success*WARNING* file /.../.../CDS.log.6 Success*WARNING* file /.../.../CDS.log.7 Success*WARNING* file /.../.../CDS.log.8 Success*WARNING* file /.../.../CDS.log.9 SuccessFailed to lock log file: /.../.../CDS.log.2012/7/18 16



• Cadence 6.14 won’t start (binary not found)

– Check $PATH variable and see if it contains the path of “virtuoso”

– Copy .bashrc from /home3/examples/. bashrc to your home directory for quick solution

• Laker won’t start (binary not found)

– Check $PATH variable and see if it contains the path of “laker”

– Copy .bashrc from /home3/examples/. bashrc to your home directory for quick solution

• Calibre won’t start: No Calibre menu in Virtuoso Layout Editor

– Copy .cdsinit from /home3/examples/.cdsinit to your home directory
