 +====== Cora Z7 Basic I/O Demo ======
  
 +{{:reference:programmable-logic:cora-z7:demos:cora2.jpg?400|}}
 +
 +----
 +===== Description =====
 +
 +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
 +
 +----
 +===== Inventory =====
 +
 +  * Cora Z7 with a MicroUSB Programming Cable
 +  * Vivado installation compatible with the latest release of this demo (2020.1)
 +    * //See [[programmable-logic:guides:installing-vivado-and-vitis|Installing Vivado, Vitis, and Digilent Board Files]] for installation instructions.//
 +
 +----
 +===== Download and Usage 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.//
