Failsafe Logic Nets
N. Tokura, Tadao Kasami, A. Hashimoto · IEEE Transactions on Computers · 1971
The basic properties and realization of failsafe combinational logic nets and failsafe sequential machines are discussed. The present note concerns totally asymmetric faiiure nets which are composed only of (+) elements and/ or (-) elements, where a (+) element is an asymmetric failure element which never fails to logical zero and a (-) element is defined similarly.
