Interface design optimisation for WASP devices

Details of defect and fault tolerance strategies used in the wafer interface blocks of wafer scale integration (WSI) associative string processor (WASP) devices are given. A structured approach to the design and optimization of redundant-path defect- and fault-tolerant signal distribution networks is presented. Monte Carlo simulations are used to analyze the success rate of various WASP signal distribution network topologies in the presence of randomly distributed defects. It is shown that the proposed signal distribution strategy lends itself well to high-speed recovery from in-operation failures.<
