Cora Z7 Basic I/O Demo

This project is a Vivado demo using the Cora Z7's RGB LED's and pushbuttons, written in Verilog.

• When programmed onto the board, the RGB LEDs will cycle from Blue to Green to Red to off
• As long as one of the two buttons is pushed, the corresponding RGB LED will be turned off

• Cora Z7 with a MicroUSB Programming Cable
• Vivado installation compatible with the latest release of this demo (2020.1)
  • See Installing Vivado, Vitis, and Digilent Board Files for installation instructions.

First and foremost, releases - consisting of a set of files for download - are only compatible with a specific version of the Xilinx tools, as specified in the name of the release (referred to as a release tag). In addition, releases are only compatible with the specified variant of the board. For example, a release tagged “20/DMA/2020.1” for the Zybo Z7 is only to be used with the -20 variant of the board and Vivado 2020.1.

The latest release version for this demo is highlighted in green.

Note: Releases for FPGA demos from before 2020.1 used a different git structure, and used a different release tag naming scheme.

Note for Advanced Users: All demos for the Cora Z7 are provided through the Cora-Z7 repository on Github. Further documentation on the structure of this repository can be found on this wiki's Digilent FPGA Demo Git Repositories (Redirect) page.

Instructions on the use of the latest release can be found in this dropdown:
