Disclosed is an integrated circuit chip test apparatus that has a module test fixture having contact pads that are adapted to make contact with signal input/output pins on an integrated circuit chip being tested. An intermediate banking box is connected to the module text fixture and a tester is connected to the intermediate banking box. The tester includes at least one bank of channels there are more pins on the integrated circuit chip than there are channels in the tester. The intermediate banking box includes switches that are connected between the contact pads and the channels. The switches are adapted to selectively connect a subset of the contact pads to the channels to connect the tester to a subset of pins, thereby allowing the tester to test a portion of the integrated circuit that corresponds to the subset of pins.

Applying parametric test patterns for high pin count ASICs on low pin count testers

An apparatus for translating a series of source words in a first language to a series of target words in a second language. For an input series of source words, at least two target hypotheses, each comprising a series of target words, are generated. Each target word has a context comprising at least one other word in the target hypothesis. For each target hypothesis, a language model match score comprises an estimate of the probability of occurrence of the series of words in the target hypothesis. At least one alignment connecting each source word with at least one target word in the target hypothesis is identified. For each source word and each target hypothesis, a word match score comprises an estimate of the conditional probability of occurrence of the source word, given the target word in the target hypothesis which is connected to the source word and given the context in the target hypothesis of the target word which is connected to the source word. For each target hypothesis, a translation match score comprises a combination of the word match scores for the target hypothesis and the source words in the input series of source words.
