# Xilinx Vivado

This article or section needs language, wiki syntax or style improvements.

Reason: Write a PKGBUILD (Discuss in Talk:Xilinx Vivado#)

ArchLinux is not officially supported by Vivado, but as happens with Xilinx ISE WebPACK, most of its features can be used with a bit of hacking.

## Prerequisites

Xilinx Vivado can be downloaded from its official website [1]. Vivado only supports 64-bit systems, so you will need a working 64-bit ArchLinux install. It's recommended to download "Vivado HLx 2015.4: Full Installer For Linux Single File Download Image Including SDK" tarball, but make sure not to be in a hurry, as it's a large download (near 9 GB). Update tarballs can also be downloaded and installed later.

### Dependencies

Installer needs ncurses5 libs, and will not work with ncurses 6 available at official repos. You can work-around this problem by installing ncurses5-compat-libsAUR from the Arch User Repository. You will also need to install lib32-libpng12 for Xilinx Document Navigator to launch.

## Installation

You must install the main package, and it is also recommended to install the latest update patch.

### Vivado and SDK

Once downloaded and unpacked the tarball, the install script must be patched to be able to properly detect the machine architecture. You can do it by going to the directory where installer is extracted and running:

    $ sed -i.original 's/uname -i/uname -m/' xsetup

Install script will be patched and original will be backed up as `xsetup.original`, just in case you need to restore it later. Once patched, just run the script; it should work perfect and install the suite without a problem:

    # ./xsetup

It is recommended to install the suite at the default location `/opt/Xilinx`, as further instructions in this page will assume the suite is installed there.

### Update patch

It is recommended to install the latest update patch, and repeat the process each time a new patch is released. Note that update patches cannot be applied to WebPACK installs. If you installed Vivado WebPACK, skip this section.

To install the update, repeat the same hack used to install the suite. Once downloaded and unpacked, go to the directory containing the extracted tarball, patch the install script and run it:

    $ sed -i.original 's/uname -i/uname -m/' xsetup
    # ./xsetup

### Licensing

If you already have a license file, you can load it using Vivado License Manager. Unfortunately, if you want to obtain a WebPack license, further steps are needed. Vivado installs old stdc++ libraries, causing problems when spawning programs not included with Vivado Suite (like your default browser). To fix this, do the following steps:

    # cd /opt/Xilinx/Vivado/2015.4/lib/lnx64.o/
    # mv libstdc++.so.6 libstdc++.so.6.orig
    # ln -s /usr/lib/libstdc++.so.6

Close any running Vivado Suite program, and launch license manager:

    $ /opt/Xilinx/Vivado/2015.4/bin/vlm

If you try obtaining a WebPack license, your default browser should open, and the license should be generated normally. If Vivado License Manager fails to automatically load the generated license, download the .lic file, and manually load it.

### Digilent USB-JTAG Drivers

To use Digilent Adept USB-JTAG adapters (e.g. the onboard JTAG adapter on the ZedBoard) from Vivado, you need to install the Digilent Adept Runtime.

Make sure you have installed fxloadAUR from the Arch User Repository .

To install the Digilent Adept Runtime, it is recommended to install digilent.adept.runtimeAUR from the Arch User Repository.

In addition, installing digilent.adept.utilitiesAUR may do good to configuring your board.

## Launching programs

To ease launching programs, you can create the following .desktop files for Vivado IDE, SDK and DocNav:

    ~/.local/share/applications/Xilinx-VivadoIDE.desktop

    #!/usr/bin/env xdg-open
    [Desktop Entry]
    Version=1.0
    Type=Application
    Name=Xilinx Vivado IDE
    Exec=sh -c "unset LANG && unset QT_PLUGIN_PATH && source /opt/Xilinx/Vivado/2015.4/settings64.sh && vivado"
    Icon=/opt/Xilinx/Vivado/2015.4/doc/images/vivado_logo.png
    Categories=Development;
    Comment=Vivado Integrated Development Environment

    ~/.local/share/applications/Xilinx-SDK.desktop

    #!/usr/bin/env xdg-open
    [Desktop Entry]
    Version=1.0
    Type=Application
    Name=Xilinx SDK
    Exec=sh -c "unset LANG && unset QT_PLUGIN_PATH && source /opt/Xilinx/SDK/2015.4/settings64.sh && xsdk"
    Icon=/opt/Xilinx/SDK/2015.4/data/sdk/images/sdk_logo.png
    Categories=Development;
    Comment=Xilinx Software Development Kit

    ~/.local/share/applications/Xilinx-DocNav.desktop

    #!/usr/bin/env xdg-open
    [Desktop Entry]
    Version=1.0
    Type=Application
    Name=Xilinx Documentation Navigator
    Exec=sh -c "/opt/Xilinx/DocNav/docnav"
    Icon=/opt/Xilinx/DocNav/resources/doc_nav_application_48.png

## Troubleshooting

### libncurses.so.5 not found

Xilinx Vivado requires version 5 of ncurses while ArchLinux has already updated to a newer version.

To obtain this library, you can either search in your pacman cache to see if you already have a local copy:

    $ ls /var/cache/pacman/pkg/ | grep ncurses

or download it from the Arch Linux Archive

After obtaining the package, simply extract `/usr/lib/libncurses.*` to `/opt/Xilinx/Vivado/<version>/lib/lnx64.o/`
