An Overview of Different TMR Design Techniques with Comparison to Alternative Fault- Tolerant Design Methods for FPGAs
نویسنده
چکیده
With growing interest in the use of SRAM-based FPGAs in space and other radiation environments, there is a greater need for efficient and effective fault-tolerant design techniques specific to FPGAs. Triple-modular redundancy (TMR) is a common fault mitigation technique for FPGAs and has been successfully demonstrated by several organizations. This technique, however, requires significant hardware resources. This paper evaluates three TMR design techniques that try to mitigate area overhead. These techniques are compared to other fault tolerant design methods in terms of area overhead, latency, and repair mode. .

Effects of radiation on electronic circuits used in extra-terrestrial applications and radiation prone environments need to be corrected. Since FPGAs offer flexibility, the effects of radiation on them need to be studied and robust methods of fault tolerance need to be devised. In this paper a new fault-tolerant design strategy has been presented. This strategy exploits the relation between cha...
