Cryptographic Accelerator

A modular cryptographic accelerator system with AES encryption, SHA-256 hashing, and memory interface capabilities.

Documentation: https://docs.uwasic.com/doc/cryptographic-accelerator-A3kJhg6Jnn

Architecture

This project implements a cryptographic accelerator with the following modules:

Digital Modules

• AES - AES encryption core with S-box, MixColumns, and key generation
• SHA - SHA-256 hashing with message schedule and padding
• Control - Control logic with FSMs, queues, and arbiter
• IO - Acknowledgment bus arbiter and module interface
• NoC - Network-on-Chip with crossbar, arbiter, and FIFO
• MemInterface - Memory controller with SPI/QSPI interface
• Top - System-level integration module

Each module is self-contained with its own source files, tests, build infrastructure, and documentation.

Quick Start

Environment Setup

# Enter the development environment
# The environment auto-detects project type (digital, analog, or mixed)
./env.sh

Building and Testing

# Lint a specific module
cd digital/<MODULE>/build/lint
make lint

# Run tests for a module
cd digital/<MODULE>/build/verification
make test

# Run synthesis
cd digital/<MODULE>/build/synthesis
make synthesis
