초록
Due to the serial nature of scan chains, the use of the boundary scan chain leads the high application costs. And with 3-state net, it is important to avoid enabling the two drivers in a net. In this paper, the new test method for 3-state nets in the multiple boundary scan chains is presented. This method configures the boundary scan cells as multiple scan chains and the test application time can be reduced. Also three efficient algorithms are proposed for testing the interconnects in a board without the collision of the test data in 3-state nets.
