(last updated on 2022/12/30)Abstract:
We present a parity-based space compaction technique that eliminates aliasing for any given fault model. The test responses from a circuit under test with a large number of primary outputs are merged into a narrow signature stream using a multiple-output parity tree. The functions realized by the different outputs of the compactor are determined by a procedure that targets the desired fault model. Experimental results for the ISCAS-85 benchmarks show that zero aliasing of single stuck-line faults can be achieved with a two-output parity tree compactor. Our findings corroborate recent results on the fundamental limits of space compaction. © 1998 IEEE.
