There are many situations when you need to protect your data, and different tools can be used to do that. For example, a safe. We develop a passcode data protection mechanism by using an FPGA board and Quartus Prime software. It allows demonstrating the basic concepts of a combination lock such as entering data, setting and checking a passcode, and displaying data.

Designing a circuit that calculates integer cube root.
In this article I will make a circuit on Verilog HDL on FPGA which will calculate cube root from integer value.
Building a Bare-Metal Application on Intel Cyclone V for Absolute Beginners
You need to have the development board with Intel (Altera) Cyclone V SoC. I used SoCKit board:
Physical unclonable functions: protection for electronics against illegal copying
Source: The online counterfeit economy: consumer electronics, a report made by CSC in 2017
Over the past 10 years, the number of fake goods in the world has doubled. This data has been published in the latest Year-End Intellectual Property Rights Review by the US Department of Homeland Security in 2016 (the most current year tracked). A lot of the counterfeiting comes from China (56%), Hong Kong (36%) and Singapore (2%). The manufacturers of original goods suffer serious losses, some of which occur on the electronics market.
Many modern products contain electronic components: clothes, shoes, watches, jewellery, cars.
Last year, direct losses from the illegal copying of consumer electronics and electronic components in the composition of other goods were about $0.5 trillion.

A Practical Implementation of the Switching Generator Using Verilog HDL
Abstract
Linear feedback shift registers are an excellent tool for implementing a pseudo random bit generator in hardware; they inhibit a simple and efficient electronic structure. Further, they are capable of producing output sequences with large periods and good statistical properties. However, standard LFSRs are not cryptographically secure, since the output sequence can be uniquely predicted given a small number of key stream bits using Berlekamp-Massey algorithm. Several methods have been proposed to destroy the linearity inherent in LFSR design. These methods include nonlinear combination generators, nonlinear filter generators, and clock controlled generators. Nevertheless, they remain vulnerable to many attacks such as side channel attacks and algebraic attacks. In 2015, a new clocked controlled generator, called the switching generator, was proposed. This new generator has been proven to be resistant to algebraic attacks and side channel attacks, while preserving efficiency and security requirements. In this project, we present a design of the switching generator using Verilog HDL.
Real-time edge detection using FPGA
Introduction
Our project implements a real-time edge detection system based on capturing image frames from an OV7670 camera and streaming them to a VGA monitor after applying a grayscale filter and Sobel operator. Our design is built on a Cyclone IV FPGA board which enables us to optimize the performance using the powerful features of the low-level hardware and parallel computations which is important to meet the requirements of the real-time system.
We used ZEOWAA FPGA development board which is based on Cyclone IV (EP4CE6E22C8N). Also, we used Quartus Prime Lite Edition as a development environment and Verilog HDL as a programming language. In addition, we used the built-in VGA interface to drive the VGA monitor, and GPIO (General Pins for Input and Output) to connect the external hardware with our board.
Stack-based calculator on the Cyclone IV FPGA board
Introduction
As first-year students of Innopolis University, we had an opportunity to make our own project in computer architecture. University suggested us several projects and we have chosen to make a stack-based calculator with reverse polish notation. One of the requirements for the project is to use FPGA board provided by the university.
As our board, we have chosen Cyclon IV. Therefore, we had to write code on hardware description language. In the course we have studied Verilog, so we have chosen it. Also, the university has additional modules for FPGA, such as numpad, thus we decided to use it in our project.
In this article, we want to share our knowledge about FPGA and Verilog, also provide you with a tutorial to repeat our project.
