“…The delay model assumed in this work is that of unbounded gate and wire delays, as in previous approaches [2,7,5,4]. This is a conservative model, which assumes that inputs in an MIC transition can arrive at any time and in any order, and that gates and wires have unknown delay.…”

“…In [2], a technique was presented to derive single-output multilevel AND-OR gate implementations. The algorithm assumes a fully-specified function and attempts to eliminate hazards even for unspecified transitions, leading to inefficient implementations.…”

This paper addresses the problem of realizing hazard-free singleoutput Boolean functions through a network of customized complex CMOS gates tailored to a given asynchronous controller specification. A customized CMOS gate network can either be a single CMOS gate or a multilevel network of CMOS gates. It is shown that hazard-free requirements for such networks are less restrictive than for simple gate networks. Analysis and efficient synthesis methods to generate such networks under a multiple-input change assumption (MIC) will be presented.

“…The impact of multi-level circuit transformations on hazards is complex, and has been studied in several previous papers [4,9,5,2,1]. A number of transformations have been identified which are hazard-preserving, i.e.…”

“…An initial solution to the multi-level hazard-free existence problem was proposed by Bredeson [2], using a recursive algorithm. However, a highly-restrictive problem formulation was used: the algorithm does not consider or introduce don't-cares, and there are also apparent bugs and missing theorems.…”
