A method is developed for obtaining a highly compressed fault table for two-level combinational circuits. A set of operations is defined through which the minimal The concept of Augmented Boolean Matrices is introduced and the same is used to derive an algorithm to find the Boolean differences, and hence fault detection Examples of such networks include arithmetic, telecommunication and error correcting The fault detection problem of combinational logic circuits is of extremeThis paper proposes and evaluates a logic level fault-tolerant method based on parity for designing combinational circuits. Experimental results on a full adder It is assumed that the response delays of all the gate elements are the same. Figure 1 shows an example of a simple two stage combinational circuit. X1,X2 and X3 are the circuit inputs and X1X2+X2X3 is the fault free response of the circuit. Interconnections between the gates are numbered. Fault diagnosis for circuit of figure 3.7. . . 53 classes: 1) Class 0 refers to combinational logic where detection of a fault, the observed output may be analyzed.
