T1  - Highly efficient test response compaction using a hierarchical x-masking technique
JF  - IEEE transactions on computer-aided design of integrated circuits and systems
N2  - This paper presents a highly effective compactor architecture for processing test responses with a high percentage of x-values. The key component is a hierarchical configurable masking register, which allows the compactor to dynamically adapt to and provide excellent performance over a wide range of x-densities. A major contribution of this paper is a technique that enables the efficient loading of the x-masking data into the masking logic in a parallel fashion using the scan chains. A method for eliminating the requirement for dedicated mask control signals using automated test equipment timing flexibility is also presented. The proposed compactor is especially suited to multisite testing. Experiments with industrial designs show that the proposed compactor enables compaction ratios exceeding 200x.

T1  - X-tolerant test data compaction with accelerated shift registers
N2  - Using the timing flexibility of modern automatic test equipment (ATE) test response data can be compacted without the need for additional X-masking logic. In this article the test response is compacted by several multiple input shift registers without feedback (NF-MISR). The shift registers are running on a k-times higher clock frequency than the test clock. For each test clock cycle only one out of the k outputs of each shift register is evaluated by the ATE. The impact of consecutive X values within the scan chains is reduced by a periodic permutation of the NF-MISR inputs. As a result, no additional external control signals or test set dependent control logic is required. The benefits of the proposed method are shown by the example of an implementation on a Verigy ATE. Experiments on three industrial circuits demonstrate the effectiveness of the proposed approach in comparison to a commercial DFT solution.

T1  - Interpreting resultative sentences in German
BT  - stages in L1 acquisition
JF  - Linguistics : an interdisciplinary journal of the language sciences
N2  - This article presents the results of a study on the interpretation and acceptance of adjectival resultatives of German children between 6 and 9 years of age and adults. These results brought to light significant differences, due to age, in the interpretation and acceptance of these resultatives, that is to say, sentences with an adjective in the final position. The youngest participants were prone to accept ungrammatical sentences by assigning a resultative meaning. The ungrammaticality of the sentences in question was not due to semantic inconsistencies but to violations of the selectional properties of verbs, as for instance in *die Kinder erschrecken die Katze angstlich 'the children frighten the cat scared'. In contrast, the adults rejected or amended those sentences. The conclusion is (a) that the children seemed to rely on the sentence structure as a primary cue to compute the meaning of an utterance and (b) that, in contrast with adults, the youngest children in particular had not yet learned the relevant semantic properties of verbs that determine the selectional restrictions and thus the syntactic options of verbs. This means that differences in interpretation and acceptance of sentences are due to differences in knowledge of semantic verb properties between adults and children. The relevant semantic knowledge increases in gradual stages during language acquisition.
