Testability Improvements Based on the Combination of Analytical and Evolutionary Approaches at RT Level
نویسندگان
چکیده
In the paper a new heuristic approach to the RTL testability analysis is presented. It is shown how the values of controllability/observability factors reflecting the structure of the circuit and other factors can be utilised to find solutions which are sub-optimal but still acceptable for the designer. The goal of the methodology is to enable the identification of such testability solutions which satisfy concrete requirements in terms of the number of registers included into the scan chain, the area overhead and the test application time as a result of RTL testability analysis. The approach is based on the combination of analytical and evolutionary approaches at the RT level.

Proposing a Novel Cost Sensitive Imbalanced Classification Method based on Hybrid of New Fuzzy Cost Assigning Approaches, Fuzzy Clustering and Evolutionary Algorithms
In this paper, a new hybrid methodology is introduced to design a cost-sensitive fuzzy rule-based classification system. A novel cost metric is proposed based on the combination of three different concepts: Entropy, Gini index and DKM criterion. In order to calculate the effective cost of patterns, a hybrid of fuzzy c-means clustering and particle swarm optimization algorithm is utilized. This ...

متن کاملNew Method of Testability Calculation to Guide RT-Level Test Generation
There have been a number of approaches to high-level testability proposed over the recent years. The known methods have been implemented in test synthesis and in guiding gate-level test generation. However, works on application of testability measures to guide high-level test generation are missing. The main aim of this paper is to fill this gap. We propose a new method for calculating testabil...

With current new urban developments, no balance can be found between green spaces and open areas present within urban networks and natural land patterns since urban networks are dominating ecological networks. Accordingly, one of the major tasks of urban and regional planners is the optimal land use allocation to urban green spaces. Therefore, to achieve this goal in this research, locations of...
