Elimination of static and dynamic hazards for multiple input changes in combinational switching circuits

Abstract

This paper deals with hazards on outputs of combinational switching circuits for multiple input changes. Certain types of function hazards are defined and are shown to be impossible to eliminate with any logic realization. Also, an interrelation between static and dynamic function hazards is established. Hazards due to delays in the logic are defined and a method of elimination is given for both the static and dynamic case.
