Abstract
A system and method for detecting hold path faults in an integrated circuit is provided in exemplary embodiments. These exemplary embodiments introduce a method of identifying data paths within an integrated circuit with statistically the highest timing slack among the data paths within the integrated circuit that cover the entire process space of the circuit. By identifying these paths (i.e., shortest data paths), a robust test pattern can be generated that directly tests for hold path faults on short data paths within the integrated circuit using one functional clock pulse.
