AN EFFICIENT ALGORITHM OF SEGMENT OVERHEAD FOR TOLERATING CELL IN SRAM-BASED FPGAs

Hanchek F et al．proposed techniques utilizing the principle of node-covering to tolerate cell faults in SRAM-Based FPGAs．A routing discipline is developed that allows each cell to cover——to be able to replace——its neighbor in a row ，but some segment overhead in the method are redundant．This paper proposes an improved method which can guarantee no redundant segment overhead in the fault-tolerant routing．
