The previous chapter examined methods for creating sensitized paths in combinational logic extending from stuck-at faults on logic gates to observable outputs. We now attempt to create tests for sequential circuits where the outputs are a function not just of present inputs but of past inputs as well. The objective will be the same: to create a sensitized path from the point where a fault occurs to an observable output. However, there are new factors that must be taken into consideration.
Test strategies described in previous chapters relied on two concepts: controllability and observability (C/O). Good controllability makes it easier to drive a circuit into a desired state, thus making it easier to sensitize a targeted fault. Good observability makes it easier to monitor the effects of a fault. Solutions for solving C/O problems include scan path and various ad-hoc methods. Scan path reduces C/O to a combinational logic problem which, as explained in Chapter 4, is a solved problem (theoretically, at least)....

Digital Systems Design and Prototyping: Using Field Programmable Logic and Hardware Description Languages, Second Edition covers the subject of digital systems design using two important technologies: Field Programmable Logic Devices (FPLDs) and Hardware Description Languages (HDLs). These two technologies are combined to aid in the design, prototyping, and implementation of a whole range of digital systems from very simple ones replacing traditional glue logic to very complex ones customized as the applications require.
This book is about the digital logic design of microprocessors. It is intended to provide both an understanding of
the basic principles of digital logic design, and how these fundamental principles are applied in the building of
complex microprocessor circuits using current technologies. Although the basic principles of digital logic design
have not changed, the design process, and the implementation of the circuits have changed.
Chapter 7 focused on methods for integrating design and test activities by capturing veriﬁcation suites written by logic designers and converting them to test programs. For some ICs, especially those with reasonably high yield, test programs derived from a thorough design veriﬁcation suite, combined with an IDDQ test (cf. Chapter 11), may produce quality levels that meet or exceed corporate requirements.
The ﬁrst ﬁve chapters provided a survey of algorithms for logic simulation, fault simulation, and automatic test pattern generation. That was followed by a brief survey of tester architectures and strategies to maximize tester effectiveness while minimizing overall test cost. We now turn our attention to methods for combining the various algorithms and testers in ways that make it possible to achieve quality levels consistent with product requirements and design methodologies.
Thus far simulation has been considered within the context of design veriﬁcation. The purpose was to determine whether or not the design was correct. Were all the key control signals of the design checked out? What about the data paths, were all the “corners” or endpoints checked out? Are we conﬁdent that all likely combinations of events have been simulated and that the circuit model responded correctly? Is the design ready to be taped out? We now turn our attention to simulation as it relates to manufacturing test.
The standard set of rules deﬁned in Combinatory Categorial Grammar (CCG) fails to provide satisfactory analyses for a number of syntactic structures found in natural languages. These structures can be analyzed elegantly by augmenting CCG with a class of rules based on the combinator D (Curry and Feys, 1958). We show two ways to derive the D rules: one based on unary composition and the other based on a logical characterization of CCG’s rule base (Baldridge, 2002).
This paper proposes a knowledge representation model and a logic proving setting with axioms on demand successfully used for recognizing textual entailments. It also details a lexical inference system which boosts the performance of the deep semantic oriented approach on the RTE data. The linear combination of two slightly different logical systems with the third lexical inference system achieves 73.75% accuracy on the RTE 2006 data.
Parametric polymorphism has been combined with inclusional polymorphism to provide natural type systems for Prolog (DH88), HiLog (YFS92), and coristraint resolution languages (Smo89), and, in linguistics, by HPSG-like grammars to classify lists and sets of linguistic objects (PS94), and by phonologists in representations of hierarchical structure (Kle91).
In this document, we present a language which associates type construction principles to constraint logic programming. We show that it is very appropriate for language processing, providing more uniform, expressive and efficient tools and treatments. We introduce three kinds of constraints, that we exemplify by motivational examples. Finally, we give the procedural semantics of our language, combining type construction with SLDresolution.
The present paper proposes a method by which to translate outputs of a robust HPSG parser into semantic representations of Typed Dynamic Logic (TDL), a dynamic plural semantics defined in typed lambda calculus. With its higher-order representations of contexts, TDL analyzes and describes the inherently inter-sentential nature of quantification and anaphora in a strictly lexicalized and compositional manner. The present study shows that the proposed translation method successfully combines robustness and descriptive adequacy of contemporary semantics. ...

Mạch số thường được chia làm hai loại: mạch tổ hợp (combinational circuit) và mạch tuần tự (sequential circuit).
Mạch tổ hợp là mạch mà các ngõ ra chỉ phụ thuộc vào các mức logic của các ngõ vào tại thời điểm đó. Mạch tổ hợp không có thuộc tính nhớ. Trong mạch tổ hợp không có bất kỳ vòng hồi tiếp nào.
