Common Issues with EDA Tools on Ubuntu 14.04 LTS

PlanAhead Segfault:

When trying to run PlanAhead you may get the following error:
/opt/Xilinx/14.5/ISE_DS/PlanAhead/bin/rdiArgs.sh: line 95: 31921 Segmentation fault      (core dumped) "$RDI_PROG" "$@"

This seems to be an issue with the packaged libjvm.so library, more information can be found at the following links:

So to fix it, do the following:
sudo apt-get install openjdk-7-jre
cd $XILINX/../PlanAhead/tps/lnx64/jre/lib/amd64/server
sudo mv libjvm.so libjvm.so.backup
sudo ln -s /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so libjvm.so

If you have this problem with the lab installation of PlanAhead, please contact Dr. Athanas



Setup a modelsim startup script with the following contents:
export PATH=/opt/system/software/Mentor/modeltech/linux:$PATH
export MODELSIM=~/modelsim.ini #otherwise it tries to write to /opt/system/ and fails
source ~/xilinx64.sh #sources settings64.sh from $XILINX

If using a 64-bit version of Ubuntu, you will need the following 32-bit libraries:
sudo apt-get install libc6:i386 libx11-6:i386 libxext6:i386 libxft2:i386 libncurses5:i386

You may encounter the following error: ** Fatal: Read failure in vlm process
The fix for this error can be found here:

Now run the vsim command to start modelsim.  You will need to run the compxlib command for your appropriate version of the Xilinx ISE tools if you haven't already.
