Introduction

This repository provides a minimal Vivado project for FPGA development on Parallella board.

Parallella board is an "18-core credit card sized computer". Read more about it here. The board has a 16-core Epiphany processor and a 2-core Zynq-7000 CPU+FPGA combo. The two are connected via FPGA fabric. FPGA code needed for that interconnect is developed in the open https://github.com/parallella/parallella-hw/

Minimal project does not include eLink interface needed to communicate with the Epiphany chip. It only contains I2C block to setup power controllers for Epiphany chip and GPIO pass-through block. So Epiphany will not be usable if you use this project as basis for your design, but on a plus side you will get much quicker synthesis times. The idea is that you can iterate on your design faster and then integrate it with the rest of the system.

How to Use

This was developed with Vivado 2015.4. Scripts might work with other versions also, but this is not guaranteed.

Manually

Folder ip_repo contains IP module called "dummy_parallella_io", you connect I2C and GPIO interfaces to Zynq and the rest make external. If you are targeting 7010 based board you have to change num GPIO pair to 12 in the "Customize block..." dialog.

Vivado Project

Don't forget to also include constraints files supplied by Adapteva. See constraints folder.

Generate Project with Scripts

Folder sample contains instructions for generating a sample project. See readme in that folder for more detail:

source ${PathToXilinxSettingsFile}
cd sample
../scripts/gen_project.sh --name test1 --7010
../scripts/gen_project.sh --name test2 --7020

LICENSE

This project uses files from Adapteva that were licensed under GPL. I do think they are working on MIT based version right now, so it should be possible to update to that in the future.
