This paper presents a solution to protect FSM implemented on FPGAs from SEU, exploiting the embedded memories available in modern FPGA devices and a Hamming code for error detection and correction. A fault tolerant FSM architecture is presented, along with a generator to automate the FSM implementation. Experimental results show that this solution is particularly suited especially when FSMs with a large number of outputs are present in the target design.
