CipherX

Project Overview

CipherX is a project aimed at verifying the Advanced Encryption Standard (AES-128) using the Universal Verification Methodology (UVM). It involves using UVM components to ensure the correctness and robustness of AES-128 encryption and decryption functionalities. The project utilizes Verilog, SystemVerilog, and Python to achieve its goals.

SDLC

The Software Development Life Cycle (SDLC) for CipherX includes:

1. Requirements Analysis: Understanding and documenting the requirements for AES-128 verification.
2. Design: Creating system architecture, flowcharts, and detailed design documents for the UVM components and AES-128 verification.
3. Implementation: Coding the UVM components and verification scripts using Verilog, SystemVerilog, and Python.
4. Testing: Conducting simulation and verification tests to ensure the AES-128 implementation meets the required standards.
5. Deployment: Integrating the verification components into a testing environment.
6. Maintenance: Monitoring and updating the verification components based on feedback and new requirements.

Highlight Testing Scripts

Testing is crucial for ensuring the correctness of the AES-128 implementation:

• encrypt.py: Encrypts data using AES-128.
• gen_random.py: Generates random data for encryption tests.
• run.sh: Executes the verification process including running simulations and tests.

Skills Used

• Verilog: For hardware description and verification.
• SystemVerilog: For UVM-based verification components.
• Python: For utility scripts and data handling.
• Shell: For scripting and automation.
