Methodology for fault tolerant system state synchronization design and its recovery from faults
 Szurman, Karel ; Fišer, Petr (referee) ; Racek, Stanislav (referee) ; Vlček, Karel (referee) ; Kotásek, Zdeněk (advisor)
In this Ph.D. thesis, a new methodology for the fault tolerant system state synchronization design and its recovery from faults is presented. A state synchronization method designed by means of the proposed methodology allows to repair the state of sequential logic elements implemented in the FPGA application logic, which cannot be repaired by the partial dynamic reconfiguration. The proposed methodology describes possible state synchronization design methods with respect to TMR granularity, dependence of the system function on its previous states and the system architecture. The methodology focuses on coarse-grained TMR architectures and state synchronization in the systems controlled by means of finite state machines or a processor. The use of the methodology is demonstrated on the CAN bus control system and the microcontroller NEO430, for which specific synchronization methods were designed. The systems reliability and new ability of the systems for recovery from faults were verified in the presence of simulated SEU faults. The experimental results and the contribution of this thesis are discussed in the conclusion.
