## Designing an FPGA Blinking Light
### Introduction
An FPGA (Field Programmable Gate Array) is a programmable logic device that can be used to implement a variety of digital circuits. In this tutorial, we will show you how to design an FPGA blinking light using the Verilog programming language.
### Prerequisites
To follow this tutorial, you will need the following:
* A basic understanding of digital logic
* A text editor
* A Verilog compiler
* An FPGA development board
### Step 1: Create a New Project
The first step is to create a new project in your Verilog compiler. In the Vivado IDE, this can be done by clicking on the “File” menu and selecting “New” -> “Project…”. In the “New Project” dialog box, enter a name for your project and select a location to save it.
### Step 2: Create a New Verilog File
Once you have created a new project, you need to create a new Verilog file. In the Vivado IDE, this can be done by clicking on the “File” menu and selecting “New” -> “Verilog File…”. In the “New Verilog File” dialog box, enter a name for your file and select a location to save it.
### Step 3: Write the Verilog Code
The following is the Verilog code for a blinking light:
“`verilog
module blinking_light (
input clock,
output led
);
reg [26:0] counter;
always @(posedge clock) begin
if (counter == 26’h3ffffff) begin
counter <= 0; led <= ~led; end else begin counter <= counter + 1; end end endmodule ``` ### Step 4: Compile the Verilog Code Once you have written the Verilog code, you need to compile it. In the Vivado IDE, this can be done by clicking on the "Compile" button in the toolbar.
