Reliability Evaluation Environment for Exploring Design Space of Coarse-Grained Reconfigurable Architectures

This paper proposes a reliability evaluation environment for coarse-grained reconfigurable architectures. This environment is designed so that it can be easily extended to different target architectures and applications by automating the generation of the simulation inputs such as HDL codes for fault injection and configuration information. This automation enables us to explore a huge design space in order to efficiently analyze area/reliability trade-offs and find the best solution. This paper also shows demonstrative examples of the design space exploration of coarse-grained reconfigurable architectures using the proposed environment. Through the demonstrations, we discuss relationship between coarse-grained architectures and reliability, which has not yet been addressed in existing literatures and show the feasibility of the proposed environment. key words: soft error, TMR, reliability, methodology
