How it works
This project implements a lightweight S-box using composite field arithmetic. It performs the non-linear transformation required for the smaller 4-bit operations.
How to test
After reset, provide an input value to ui_in[3:0]. The corresponding S-box output will appear on uo_out[3:0]. You can verify the mapping against the standard AES S-box table or the specific implementation logic defined in the testbench.
