Detection of the location of the hazard during and after the design of combinational circuits

Abstract

Delay fault and glitch fault cause hazards that are structure hazard and function hazard. During design process we can use many methods to identify and remove structural hazard [1-2],[3]. However, with function hazards, determination and remove much more difficult. In this paper we introduce a new solution to determine the structure hazard by the Truth table - Matrix mathematics M ethod and method for determining function hazard over how to determine crosstalk fault [4-71.
