The Application of the Boundary-Scan Testing Technology Based on Genetic Algorithms

摘要

The boundary-scan testing technology is proposed in this paper. It can optimize the testing vectors globally with the global optimality of genetic algorithms. Firstly the developing course of boundary-scan testing technology is introduced. Through the analysis of architecture and function of system, it indicates that on the premise of maintaining high fault coverage, to search an optimal interconnected testing aggregate, to improve the testing speed and compress the testing vectors is one of the keys of efficient boundary-scan test in engineering application. Secondly the basic concept, operation steps and the realization of global optimality of genetic algorithms are introduced and analyzed. Thirdly, the project of designing testing vectors of boundary-scan test with genetic algorithms is introduced. Through this project the optimal testing vectors can obtained with less complexity and better categoricalness. Finally a testing circuit board has been designed with the testing designing method. The result of the experiment showed the efficiency of this testing algorithm.
