One is Cone Partitioning technique which is used to divide the circuit into number of sub- circuits and other one is Reduced Ordered Binary Decision Diagram (ROBBD) to generate the test pattern. In the proposed scheme, to overcome the issue in the existing system two Algorithms are used which are applied for both feedback bridging fault and non-feedback bridging fault. This controller design supports important features such as real time fault detection, fail safeness and. In the existing system, testing of bridging fault covers only non- feedback fault that causes Oscillations which is difficult to detect the fault. architecture for synchronous sequential circuits. The differential amplifier is a voltage subtractor circuit which produces an output voltage proportional to the voltage difference of two input signals. The bridging fault is divided into feedback bridging fault and non-feedback bridging fault. There are various types of fault such as transition fault, delay fault and bridging fault. Detection of fault is more difficult in Sequential circuits than Combinational circuits. Novelty detection and known faults classification are commonly treated as two different problems and trained as two separate models and then applied in sequence. Digital circuit can be classified into Combinational and Sequential circuits. Fault Diagnosis Digital System Fault Simulation Sequential Circuit Combinational Circuit.
