摘要
This paper describes a new method for exact hazard-free logic minimization of Boolean functions, Given an incompletely-specified Boolean function, the method produces a minimum-cost sum-of-products implementation which is hazard-free for a given set of multiple-input changes, if such a solution exists, The method is a constrained version of the Quine-McCluskey algorithm, It has been automated and applied to a number of examples. Results are compared with results of a comparable non-hazard-free method (espresso-exact [33]). Overhead due to hazard elimination is shown to be negligible.
