An Innovative Simple Test Circuit for Single-Phase Short Circuit Making Test of High-Voltage Switching Devices

Nowadays, high-voltage circuit breakers have reached such high short-circuit capabilities that testing them under the full rated voltage is generally not possible with direct tests, and they are conducted by using the synthetic test methods. Although the phenomena associated with making tests is of particular importance especially in case of load break switches, but making tests are rather d...

Test Access Circuit for Education

In this paper we present our new educational chip. This chip is one of three chips which were designed for educational purposes within the framework of the IST project REASON. Nowadays the Boundary Scan (BS) has become to be a standard for diagnostic access to the circuits, for in-circuit programming and for several other tasks. The Boundary Scan access is sometimes combined with a scan chain o...

Sequential Circuit Test Generationin

|Test generation using deterministic fault-oriented algorithms is highly complex and time-consuming. New approaches are needed to augment the existing techniques, both to reduce execution time and to improve fault coverage. In this work, we describe a genetic algorithm (GA) framework for sequential circuit test generation. The GA evolves candidate test vectors and sequences, using a fault simul...

Application of Simple Genetic Algorithmsto Sequential Circuit Test

In this work we investigate the eeectiveness of genetic algorithms (GAs) in the test generation process. We use simple GAs to generate populations of candidate test vectors and to select the best vector to apply in each time frame. A sequential circuit fault simula-tor is used to evaluate the tness of each candidate vector , allowing the test generator to be used for both com-binational and seq...
