Abstract

This paper presents a divide and conquer approach for the hazard-free realization of combinational networks. The circuit is partitioned into a set of supergates which are individually made hazard-free. Since each supergate has to be implemented in two-level form, the circuit can be implemented as a multilevel network of PLAs. A modified supergate partitioning for multi-output circuits has also been proposed. Experiments to evaluate the testability of the synthesized circuits have been carried out.
