When a feedback bridging fault occurs in a combinational circuit and it is activated, logical oscillation may occur in the circuit. In this paper, some electrical conditions are proposed to identify whether a feedback bridging fault occurs logical oscillation. Also, it is proposed how to estimate the oscillation frequency. They are based on piece linearlized models and do not require circuit simulation of large size of circuits. They are evaluated by some experiments. In the experiments, all of the feedback bridging faults occurring logical oscillation are identified. Also, oscillation frequencies larger than the ones obtained by SPICE simulation are derived by the proposed estimation method in the experiments. It promises us that the methods will be used for identifying such bridging faults and estimating the oscillation frequencies.
