Content: In times of modern computing systems, safety systems are based rather on microcontroller, programmable logic control (PLC), or even relay technology. At first glance this might seem old-fashioned or even anachronistic. In fact, a technical approach is rather conservative by nature. Nevertheless, there is a need for more modern, programmable electronics in the field of safety technology, such as the use of modern integrated circuits. Integrated electronic circuits and their design methodologies indeed have rapidly become more sophisticated in recent years. However, this development leads to ever-growing complexity of integrated circuits, and thus to an increased probability of inherent errors, thus enhancing the challenges for their use within safety-relevant or even safety-critical systems. In particular, the susceptibility of integrated circuits for soft-errors increases with the semiconductor evolution. Nevertheless, due to their programmability and efficiency, FPGAs and ASICs provide a suitable platform for use in safety related systems. Especially SRAM-based FPGAs, which provide a considerable degree of flexibility due to reconfigurability at run-time, present an attractive and yet not fully exploited platform. This dissertation addresses a safety and reliability design of programmable electronic systems using SRAM-based FPGAs.
