Zusammenfassung:To the casual observer, glitches occurring in quasi delay-insensitive logic would appear to cause incorrect operation and render the circuits unusable. This paper presents an informal analysis of the effects of glitches occurring on the long interconnect wires connecting logical units of a network-on-chip (NoC) using quasi delay-insensitive (QDI) techniques. This is followed by the introduction and analysis of a set of techniques to reduce the likelihood and impact of such hazards affecting the circuit. Post layout area and performance impacts are presented for a 90 nm process.
