Topic 1: Smart Parking System with Ultrasonic Sensors
Description: Design and implement a smart parking system using VHDL on the Nexys A7 FPGA board. The system will utilize multiple ultrasonic sensors (HS-SR04) connected to the Pmod connectors for detecting the presence and distance of vehicles within parking spaces. Develop algorithms to analyze sensor data and determine parking space availability. Visualize parking space occupancy status using LEDs, while displaying distance measurements on the 7-segment display.
Topic 2: Relay-Controlled Sound Synthesizer
Description: Develop and implement a sound synthesizer utilizing relays on the Nexys A7 FPGA board. Rather than generating audio signals directly, the system employs relays connected to Pmod connectors to produce audible sounds by managing the activation and deactivation of relay switches. Users can compose and play basic melodies by programming the relay sequences. Push buttons will serve as controls for play, stop, and song navigation, while LEDs and a 7-segment display will provide visualization of the melody and information about the songs.
Topic 3: PWM-Based Servo Motor Controller
Description: Develop a PWM-based servo motor controller using VHDL on the Nexys A7 FPGA board. Utilize the FPGA's PWM output capability to generate signals for controlling multiple independent servo motors connected to the Pmod connectors. Implement algorithms to adjust the angle of the servo motors based on user input received from buttons or switches. LEDs will offer visual feedback on the servo position or controller status.
Topic 4: PWM-Based Tone Generator
Description: Develop a tone generator using PWM on the audio jack connector of the Nexys A7 FPGA board to produce simple musical tones or melodies. Users will be able to adjust parameters such as frequency and duration using buttons or switches. LEDs will offer visual indication of the currently generated tone.
Topic 5: Implementation of Basic Ciphers
Description: This project aims to demonstrate various simple ciphers, such as the Vernam Cipher, Caesar Cipher, Atbash Cipher, and potentially others, using basic logic gates and flip-flops on the Nexys A7 FPGA board. Each cipher enabling users to input plaintext messages and observe the resulting ciphertext generated by the encryption process. Buttons and switches can serve as input devices for users to input plaintext messages and control the encryption/decryption process. LEDs can provide visual feedback on the status of the encryption/decryption process, indicating ready to receive input, encryption/decryption in progress, and complete. The 7-segment display shows the ciphertext or plaintext output.
Advanced Topic 1: Digital Voltmeter with Voltage Data Logging
Description: This project involves the development of a digital voltmeter using VHDL on the Nexys A7 FPGA board to accurately measure and log voltage levels. The system will interface with analog-to-digital converters (ADC) via the Pmod connectors to sample voltage signals from external sources. The measured voltage will be displayed in real-time on the 7-segment display for user visualization. LEDs will provide visual feedback on the measurement status or indicate voltage thresholds. Additionally, the system can log the voltage data to an external memory device for future analysis.
Advanced Topic 2: VGA Image Rendering and Manipulation
Description: This project involves the development of generating images using VGA output on the Nexys A7 FPGA board. The system will implement algorithms for image rendering and manipulation, enabling the creation of basic shapes, patterns, and color gradients. It will adhere to VGA timing specifications for pixel generation and synchronization, ensuring compatibility with standard VGA displays.
The objective of this group project is to collaborate within small teams of 3-4 students, explore a chosen topic, utilize lab components, develop innovative solutions, simulate and execute these solutions, generate project documentation, and present the final outcomes. Team members are responsible for organizing and assigning roles and tasks among themselves.
-
Students will work on the project in the lab during Weeks 8 to 12 (or 13) of the semester, culminating in a joint presentation.
-
Students must submit a link to their GitHub repository containing the VHDL project, required images, documents, and a descriptive README file. Students use the README file for the presentation.
-
All FPGA code must be written in VHDL and must be implementable on the Nexys A7-50T board using the development tools provided during the semester, specifically Vivado.
-
Use components designed and tested during the semester.
-
Follow ethical rules regarding plagiarism, licensing, and policies for the use of generative artificial intelligence.
-
Provide detailed simulation testbenches for all your new components.
-
Physical implementation on FPGA is necessary, not just computer simulation.
-
Students create an illuatrative video (<1 min.) about their application with explanatory captions and possibly background music. Upload it to YouTube as part of the project. Video is played at the beginning of the presentation. (Video can be used to promote the course on LinkedIn.)
-
Never, ever use
rising_edgeorfalling_edgeto test edges of non-clock signals under any circumstances! -
Use hierarchical design, ie. instances, top-level, several files, etc.
-
Use synchronous entities with rising
clk. -
In a synchronous process, the first thing to do is the test of clock edge, then synchronous reset. The only exception is asynchronous operations (try to avoid them).
-
Use only input
inor outputoutports and notinout. -
Use
waitstatements only in simulations. -
Except Vivado, we encourage the use of other tools as well:
- EDA Playground
- TerosHDL
- ghdl + GtkWave
- ModelSim
- Live Share, a Visual Studio Code plugin for a real-time collaborative development
- other tools

An abstract is a short summary of your project, usually about a paragraph (6-7 sentences, 150-250 words) long. A well-written abstract serves multiple purposes: (a) an abstract lets readers get the gist or essence of your project quickly; (b) an abstract prepares readers to follow the detailed information, description, and results in your report; (c) and, later, an abstract helps readers remember key points from your project.
