1. Getting Started with FPGA

Introduction

Here are the essential steps and notes to begin programming FPGAs using Xilinx Vivado on the BASYS 3 board.

Important Notes

Know your FPGA chip and exact model number.
Understand the purpose of jumper settings.
Use a proper data-transfer USB cable (not a charging-only cable).

Steps to Program an FPGA

Create a new Vivado project.
Select the correct FPGA chip/model (e.g., Artix-7 XC7A35T-1CPG236C).
Use consistent naming for your top module.
Add your design source files (VHDL or Verilog).
Create or add your constraints file (XDC) for pins.
Run Synthesis.
Run Implementation.
Generate Bitstream.
Open Hardware Manager → Open Target → Auto-connect.
Program Device with the generated bitstream.

2. Role of constrain file FPGA

Here are the essential highlights of constrain file in FPGA

Important Notes

Behavioral file tell how to behave while the constrain file spicify which component to use in FPGA board
The constrain and FPGA files go hand in hand in order for project to work
The code level of constrain and behaviour should match

3. Behavioural code explored

Here are the essential highlights

Important Notes

Programming behaviour code is all about frequency
The entity name should be match with file name
The counters reduces and mold the original clock frequency to processs futher
