AES

Features

• Pipelined AES core supporting 128, 192, and 256-bit keys.
• AES-CTR mode for encryption/decryption.
• AES-GCM mode for authenticated encryption/decryption with associated data.

Prerequisites

• GNU Make
• Simulator: Synopsys VCS or Mentor Graphics ModelSim.

Run Simulation

You can run simulations using either VCS or ModelSim. The default key length is 128 bits.

Using VCS:

# Run AES core test
make test_aes.vcs

# Run with specific key length (e.g., 256 bits)
make test_aes.vcs KEY_LENGTH=256

Using ModelSim:

# Run AES core test
make test_aes.vsim

# Run with specific key length
make test_aes.vsim KEY_LENGTH=256

Python Reference Tests

To verify the Python implementation against test vectors:

pytest
