# AES Crypto Engine ### Authors Alex Pearson, Scott Lawson, Daniel Collins ### Description Parameterized AES encryptor and decryptor written in System Verilog. Supports the three standardized key sizes (128 bits, 192 bits, and 256 bits), chosen at elaboration time. Adheres to the Advanced Encryption Standard (AES) published by the National Institute of Standards and Technology (NIST), AES FIPS PUB 197. Verified using test vectors provided by the standard and produced by the [LibTomCrypt C library](https://github.com/libtom/libtomcrypt). Verification done in simulation with [Mentor Graphics ModelSim®](https://www.mentor.com/products/fv/modelsim/) and emulation on the [Mentor Graphics Veloce®](https://www.mentor.com/products/fv/emulation-systems/). ### Repository Contents | Path | Description |---------------------------|------------ | / | Makefile, README, Veloce config file |   docs/ | Project documentation |    src/ | Documentation source files for editing |    third_party/ | Reference documentation used in the design and verification of this project |   src/ | AES Processor source code |    mem/ | Veloce memory-modeled lookup tables |   test/ | Verification resources |    bench/ | System Verilog testbenches |    gen/ | Source code for C program to generate test vectors, scripts to obtain LibTomCrypt for building |    hvl/ | Top-level System Verilog testbench for Veloce emulation |    vectors/ | Text files containing test vectors for all test benches ### Makefile All of the recipes in the provided Makefile assume the user is on a Linux system that supports ModelSim in both puresim and veloce modes, and that the current working directory is the root of this repository. | Recipe | Action |---------------| ------ | compile | Compiles all source and testbench files | sim_\ | Simulates the specified module using its testbench (note: the recipe names do not exactly match the module names - see Makefile contents for the recipe to run a specific testbench) | all | Compiles all modules for all valid key widths, and runs all testbenches for each key width. All output is tee'd into all.log. After everything is complete, grep is used to search the log file for reported errors and warnings. A note is displayed to inform the user if any warnings or errors are present in the log file. ##### Options **MODE** Specifies the simulation mode. Valid modes are: | Mode | Description | |----------|--- | standard | No Veloce support or dependencies. Cannot run top-level testbench, only sub-module testbenches. | puresim | Veloce simulation | veloce | Veloce emulation (only the top-level testbench is run on the emulator) If simulating for any mode besides puresim, this option must be specified for both compilation and simulation. If unspecified, default is puresim. **INFER_RAM** Specifies whether to infer RAMs for the SBox (KeyExpansion and Subbytes) and GF LUTs (MixColumns). | Infer RAMs | Description | |------------|--- | y | Yes, infer RAMs for the SBox and GFLUT memories. | n | No, do not infer RAMs for the SBox and GFLUT memories. This option is off by default. If it is used, the Transactor must be modified to remove instantiation of the 256-bit encoder and 256-bit decoder. The entire design will not fit on one board, which is all our Veloce has. The design is limited by the crystal chips used when inferring RAMs. ##### Examples # compile all modules, run ExpandKey testbench in puresim mode make compile make sim_expandkey # compile all modules with inferred RAMs, run top level HVL testbench in veloce mode make compile MODE=veloce INFER_RAM=y make sim_encoderdecoder MODE=veloce # compile all modules and testbenches for all key widths and run all testbenches on the Veloce emulator make all MODE=veloce
