New Horizons

Welcome to my blog

My name is Sven Andersson and I
work as a consultant in embedded
system design, implemented in ASIC
and FPGA.
In my spare time I write this blog
and I hope it will inspire others to
learn more about this fantastic field.
I live in Stockholm Sweden and have
my own company

Zynq design from scratch. Part 8.
Starting Vivado

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.

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.

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?
