power trace issue

  1. i am working on sakura-x( Sasebo GIII) board for side ch attacks. even after changing the AES S-box to some other S-box, i am getting output of original AES(283 irreducible polynomial) S-box.
  2. how can i implement 369-irreducible polynomial in the board for side ch attacks?
  3. is there AES algorithm hardcoded in the board(kintex-7 of sasebo GIII)?
