This tutorial is condensed from Digilent's excellent tutorial on the Vivado IP integrator and has been made specific to the PYNQ-Z1 board.

Prerequisites

Install Vivado and set it up for the PYNQ-Z1 board. Instructions are here.

Creating a Vivado Project

1. Launch Vivado GUI (with command-line options to suppress annoying output)

Prerequisites

1. If you haven't already, create a free Xilinx account.

Installing Vivado HLx 2018.3

1. On your local machine, download the Vivado HLx 2018.3 Linux Self Extracting Web Installer.
2. Copy the installer to your FarmShare home directory:

> scp Xilinx_*.bin {SUNet ID}@rice:~/. 

3. Login to FarmShare with X-forwarding.

1. Download and install MSYS2: https://sourceforge.net/projects/msys2/
2. Open MSYS2 shell and run pacman -Syu
3. After some time you will be prompted to close the MSYS2 shell by clicking the "X" button, which you should do :-)
4. Relaunch MSYS2 shell and run pacman -Su
5. Install the required packages for Verilator:

> pacman -S git make autoconf gcc flex bison man perl

6. Clone the Verilator source and build the latest stable release:
