چکیده
This paper addresses the issue of Single-Event Upset (SEU) in quasi delay-insensitive (QDI) asynchronous circuits. We show that an SEU can cause abnormal computations in QDI circuits beside deadlock, and we propose a general method to make QDI circuits SEU-tolerant. We present a simplified SEUtolerant buffer implementations for CMOS technology. Finally, we present a case study of a one-bit comparator and show SPICE-simulation results.

Protecting QDI interconnects from transient faults using delay-insensitive redundant check codes
Asynchronous circuit design is a promising technology for large-scale multi-core systems. As a family of asynchronous circuits, Quasi-delay-insensitive (QDI) circuits have been widely used to build chip-level long interconnects due to their tolerance to delay variations. However, QDI interconnects are vulnerable to faults. Traditional fault-tolerant techniques for synchronous circuits cannot be...

متن کاملModeling and Synthesis of Multi-rail Multi-protocol QDI Circuits
Quasi-Delay-Insensitive (QDI) circuits behave correctly independently of arbitrary delays in gates or wires, which gives them many advantages. However, there are a lot of restrictions for the design of this type of circuits, making them difficult to synthesize automatically. This paper presents a new methodology to model and synthesize QDI asynchronous circuits. The targeted circuits use the mu...
متن کاملQuasi-delay-insensitive Circuits Are Turing-complete
Quasi-delay-insensitive (QDI) circuits are those whose correct operation does not depend on the delays of operators or wires, except for certain wires that form isochronic forks. In this paper we show that quasi-delay-insensitivity, stability and non-interference, and strong connuence are equivalent properties of a computation. In particular, this shows that QDI computations are deterministic. ...
متن کاملMulti-Threshold Asynchronous Circuit Design for Ultra-Low Power
This paper presents an ultra-low power circuit design methodology which combines the MultiThreshold CMOS (MTCMOS) technique with quasi delay-insensitive (QDI) asynchronous logic, in order to solve the three major problems of synchronous MTCMOS circuits: (1) Sleep signal generation, (2) storage element data loss during sleep mode, and (3) sleep transistor sizing. In contrast to most power reduct...
