On the synthesis of unidirectional combinational circuits detecting all single faults

Abstract

In this paper authors consider the problem of concurrent error detection (CED) system of combinational circuit with unidirectionally independent outputs design using modulo codes with the summation. Considering of error detection features of modulo codes with the summation allows designing CED systems with reduced complexity comparing with the ones based on the classic Berger code. Authors determine conditions of application of modulo codes with the summation for CED system of combinational circuit with unidirectionally independent outputs design.
