vivado-git

Trying to make Vivado more git-friendly.

Requirements

• Tested on Vivado 2019.2

Windows

• Git for Windows
• Add C:\Program Files\Git\bin (or wherever you have your git.exe) to your PATH

Linux

• Git

Installation

Add Vivado_init.tcl (or append the relevant lines if you already have something in it) along with the scripts directory to:

• %APPDATA%\Roaming\Xilinx\Vivado on Windows
• ~/.Xilinx/Vivado on Linux

How it works

Vivado is a pain in the ass to source control decently, so these scripts provide:

• A modified write_project_tcl_git.tcl script to generate the project script without absolute paths.

• A git wrapper that will recreate the project script and add it before committing.

• A Tcl script (wproj) to just create the Tcl project generator script without using git. This script can be called from the Tcl Console on Vivado.

Workflow

1. When first starting a project, create it in a folder called vivado_project (e.g. PROJECT_NAME/vivado_project). All the untracked files will be under this directory.

2. Place your source files anywhere you want in your project folder (e.g. PROJECT_NAME/src).

   Here is an example of a possible project structure:

   PROJECT_NAME
       ├── .git
       ├── .gitignore
       ├── project_name.tcl         # Project generator script
       ├── src/                     # Tracked source files
       │   ├── design
       │   │    ├── *.v
       │   │    └── *.vhd
       │   ├── testbench
       │   │    ├── *.v
       │   │    └── *.vhd
       │   ├── blockdesign
       │   │    ├── ui
       │   │    ├── ip
       │   │    ├── *.bd
       │   │    └── ...
       │   └── ...
       └── vivado_project/          # Untracked generated files
           ├── project_name.xpr
           ├── project_name.cache/
           ├── project_name.hw/
           ├── project_name.sim/
           └── ...
   

3. Initialize the git repository with git init on the Tcl Console. This will create the repository, automatically change to your project directory (PROJECT_NAME), generate the .gitignore file and stage it.

4. Stage your source files with git add.

5. When you are done, git commit your project. A PROJECT_NAME.tcl script will be created in your PROJECT_NAME folder and added to your commit.

6. Afterwards, when opening the project after cloning it, do it by using Tools -> Run Tcl Script... and selecting the PROJECT_NAME.tcl file created earlier. This will regenerate the project so that you can continue to work.

Notes

Board part repository paths

Only board part repositories inside the project are stored in the project generator script.

If you have a system wide board part repository, you will need to add it manually after recreating the project from the Tcl script (e.g. via Settings --> Board Repository).
