This work presents a fault-tolerance method able to deal with the combination of open and shortcut faults in SRAM-based FPGA routing connections, which may affect one or more redundant domains of a given protected design. The method is based on duplication of the internal critical connections, creating a local redundancy in the routing whenever needed. Therefore, when the critical connection fails, the redundant routing enforces the propagation of the original value. Preliminary results, performed by fault injection, show the efficiency of this method to improve reliability in the routing
