Zynq design from scratch. Part 8.
Starting Vivado

For more information about using the latest version (2014.2) of Vivado see part 50 of this blog.

Before starting Vivado we must setup the Xilinx design environment using one of the following commands:

source /opt/Xilinx/Vivado/2013.4/ (64bit Ubuntu)
source /opt/Xilinx/Vivado/2013.4/ (32bit Ubuntu)

Add one of these lines to your .bashrc file to setup the environment in every terminal window you open. We are now ready to start Vivado. Here is what happens.

vivado &

Not the best start we could have hoped for. Looking for a solution I found this in the Xilinx forum. Let's see if it solves our problem. First we have to install openJDK if not aldready done.
(This problem has been fixed in Vivado 2015.1)
sudo apt-get install openjdk-7-jre

We will use the openJDK Java installation instead of the one that came with the Vivado installation.

sudo mv /opt/Xilinx/Vivado/2013.4/tps/lnx64/jre/lib/amd64/server/

sudo ln -s /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/

Let's try again.

vivado &

Congratulations! We have Vivado running. Now it is time to do some real work.

When you install Vivado as root the directory .Xilinx/Vivado/2014.2 will be owned by root. You can fix the problem by changing the permissions like this: sudo chmod 777 ..../Vivado/2014.2 or change the owner to your userid. This a bug that should be fixed by Xilinx

Thanks a lot for this tutorial. I was able to launch Vivado however I see this error everytime-

You shouldn't run the program as 'root'

Hi Deni,

Here is what I did.

For all of us using non-english keyboards add the following lines to .bashrc

export LANG="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
export LC_NUMERIC="en_US.UTF-8"

Hy Svenand!

I tried to install vivado 14.1 based on your tutorial (I know it is for 13.4), I think I did everything correctly, but when I try to create block design I keep getting the message:
ERROR: [Vivado 12-106] *** Exception: java.lang.NumberFormatException: For input string: "0,01" (See /root/vivado_pid15030.debug)
The problem should be with java, but I don't know what is it, or how to solve it.
Can you point out what did I do wrong?
