This paper examines architectural techniques for providing concurrent error detection in self-timed VLSI pipelines. Signal pairs from Differential Cascode Voltage Switch Logic are compared with a checker that is composed of a tree of dual-rail (morphic) comparators to detect errors and signal completion. An efficient implementation is shown that compares favorably in speed and area with conventional completion signal generators. A simple pipeline is examined with error checkers at each computation stage and hand-shaking control circuits that are modified to improve error detection. Its error-detecting properties are discussed, and preliminary error simulation results are presented. Based on these studies we have concluded that self-timed logic offers considerable fault-tolerance potential due to its built-in redundancy that can be effectively exploited for error checking. > |
