On the Selection of Efficient Arithmetic Additive Test Pattern Generators
نویسندگان
چکیده
Built-in self-test (BIST) strategies require the implementation of efficient test pattern generators (TPG) which allow the excitation and observation of potential faults in the circuit. Arithmetic additive TPGs (AdTPG) allow existing internal datapaths to be reused to perform this operation without a penalty in the circuit area. AdTPGs are configured by means of triplets: a combination of seed, increment and number of times the increment is added to the seed. Since the selection of triplets is crucial to the quality of the test vectors obtained and the test resources used, an emerging research interested in the topic is observed. In this paper, a method for generating efficient triplets which enable a reduction of memory requirements and test application time for a given fault coverage (FC) level is presented.

Mental Arithmetic Task Recognition Using Effective Connectivity and Hierarchical Feature Selection From EEG Signals
Introduction: Mental arithmetic analysis based on Electroencephalogram (EEG) signal for monitoring the state of the user’s brain functioning can be helpful for understanding some psychological disorders such as attention deficit hyperactivity disorder, autism spectrum disorder, or dyscalculia where the difficulty in learning or understanding the arithmetic exists. Most mental arithmetic recogni...
متن کاملAdditive generators in interval-valued fuzzy set theory
In this paper we study generators of t-norms on the lattice LI of closed subintervals of the unit interval. Starting from a minimal set of axioms that any addition and multiplication operator on LI must fulfill, we investigate the properties of the additive and multiplicative generators on LI obtained using these arithmetic operators. We also investigate under which conditions the generators on...

In this paper, we studied numerically both kinematic and dynamic models of a biologically inspired mammal-like octopod robot walking with a tetrapod gait. Three different nonlinear oscillators were used to drive the robot’s legs working as central pattern generators. In addition, also a new, relatively simple and efficient model was proposed and investigated. The introduced model of the gait ge...
متن کاملScalable Test Generators for High-Speed Datapath Circuits
This paper explores the design of efficient test sets and test-pattern generators for on-line BIST. The target applications are high-performance, scalable datapath circuits for which fast and complete fault coverage is required. Because of the presence of carry-lookahead, most existing BIST methods are unsuitable for these applications. High-level models are used to identify potential test sets...

Arithmetic additive test pattern generators (AdTPGs) are now being proposed as an alternative to linear feedback shift registers (LFSRs) because of their reduced area overhead impact. As in the case of LFSRs, the compactness of the information required in memory and the test generation time needed to achieve a specified fault coverage level (FC) have a significant impact on the necessary resour...
