Continuous research and development in the field of particle accelerator detector electronics focusing on Static Random Access Memory (SRAM) Field Programmable Gate Arrays (FPGA) confirmed that the use of fault tolerance techniques is inevitably required for safe operation in radiation susceptible environments. Therefore, several formerly presented research results dealt with the well-known partial configuration scrubbing, especially blind scrubbing, supported by a minority of such devices. Current approaches address techniques on Register-Transfer-Level, especially Hamming based Finite State Machine (FSM) design, in combination with Triple Modular Redundancy (TMR). Due to the fact that commercially available tools which apply global TMR fault tolerance to existing hardware designs are quite expensive and are working on netlists only, manual Hamming FSM designs with TMR have been created and tested in GeV proton particle beam at the COSY accelerator in Juelich, Germany.
