Fault tolerance in co-evolutionary communication of EHW modules

Evolvable Hardware (EHW) is a new concept that applies evolutionary algorithms to hardware design. Based on previous work on co-evolutionary communication of EHW modules, this paper investigates the new feature of fault tolerance for this model. A fault model is built for the communication line between EHW modules. The experiment demonstrated in the presentation is the simulation of injecting stuck/bridging faults into an EHW-based serial adder that has been previously developed. The outcomes imply an outstanding feature of fault tolerance in this system with 100% fault coverage, which paves the way for bio-inspired approaches to fault tolerant design instead of the classic ones.
