If you want to build your own design, I suggest you install Vivado, and follow the instructions to rebuild the existing base design.

You could try follow parts of this tutorial to add an AXI GPIO controller to connect to the pins you need:

Tutorial: Creating a hardware design for PYNQ

Creating a new hardware design for PYNQ The previous tutorial showed how to rebuild the reference base design for the PYNQ-Z1/PYNQ-Z2 boards. This tutorial will show you how to create a new Vivado hardware design for PYNQ. This tutorial is based on the v2.4 PYNQ image and will use Vivado 2018.2. The PYNQ-Z2 board was used to test this design. If you are using the PYNQ-Z1 or PYNQ-Z2, first make sure the board files have been installed. Download the PYNQ-Z1 board files or the PYNQ-Z2 board files,…

(You only need 1 AXI GPIO controller, and you don’t need the BRAM controller).
