  text: 'The test for small delay faults is of major importance for predicting potential
    early life failures or wearout problems. Typically, a faster-than-at-speed test
    (FAST) with sev¬eral different frequencies is used to detect also hidden small
    delays, which can only be propagated over short paths. But then the outputs at
    the end of long paths may no longer reach their stable values at the nominal observation
    time and must be considered as unknown (X-values). Thus, test response compaction
    for FAST must be extremely flexible to cope with high X-rates, which also vary
    with the test frequencies. Stochastic compaction introduced by Mitra et al. is
    controlled by weighted pseudo-random signals allowing for easy adaptation to varying
    conditions. As demonstrated in previous work, the pseudo-random control can be
    optimized for high fault efficiency or X-reduction, but a given target in fault
    efficiency cannot be guaranteed. To close this gap, a hybrid space compactor is
    introduced in this paper. It is based on the observation that many faults are
    lost in the compaction of relatively few critical test patterns. For these critical
    patterns a deterministic compaction phase is added to the test, where the existing
    compactor structure is re-used, but controlled by specifically determined control
    vectors. '
