Abstract

The stuck-at fault model, which is commonly used with fault simulation, does not adequately evaluate the effects of bridging faults (shorts between adjacent signal lines) in CMOS circuits. Tests for bridging faults can be performed on automatic test equipment, and the test vectors can be evaluated using logic simulation.
