Input/Output-Interlocking for Fault Mitigation in QDI Pipelines

In asynchronous quasi delay-insensitive (QDI) circuits, temporal masking is a serious concern because of their event-driven behavior, which makes them prone to environmental effects: Data acceptance windows, e.g. are defined by transitions (token/acknowledgement) alone, without temporal bounds, therefore a glitch occurring anytime throughout such a window cannot be distinguished from an expected, ...
