Selecting a small subset of the set of functional vectors for performing IDDQ measurement has previously been .studied for leakage but not f o r bridging faults. Algorithms for this problem for all two line bridging faults, in combinational a n d sequential circuits, along with experimen,tal results are presented.

IDD Q measurement is a time consuming process. Thus, reducing the number of IDDQ measurements have a great impact on the test time. Carefully selecting a few IDDQ measurement points is therefore an important problem. This problem has been studied for detecting leakage faults but not for bridging faults. We present novel algorithms to select IDDQ measurement points to detect bridging faults. Experimental results obtained are very encouraging. The method can also be used: by test generators to compress 1DDQ test sets; and to maximize the fault coverage when a fixed number of measurement points are given.
