%0 Journal Article %T Modified ATPG method by feeling don¡¯t care bit for optimization of switching activities %A Chetan Sharma %J International Journal of Computer Technology and Applications %D 2011 %I Technopark Publications %X Test power is major issue of current scenario of VLSI testing. There are different test pattern generation techniques for testing of combinational circuits. This paper gives a new advancement in automatic test pattern generation method by feeling don¡¯t care bit of the test vector to optimize the switching activities. Finally this concept produces low power testing. %K ATPG method %K D Routh¡¯s algorithm %K Boolean difference method %K Switching activity %U http://ijcta.com/documents/volumes/vol2issue3/ijcta2011020307.pdf
