In this paper, we analyze the problems of conventional and previous method on delay test architecture and test procedure in IEEE 1149.1. To solve them, we propose two kinds of delay test architecture, and one common test procedure. Previous method has an inefficient test procedure, and hardware overheads on the rate of the number of CUT(circuit under test)s signal lines. The first architecture ARCH-I, we proposed, is to detect the delay defect of 0.5 Ttck size, and have a fixed small amount of hardware overhead. And first method is to test as 2 more faster than previous. Seconde architecture ARCH-II is to detect the delay defect of 1 Ttck size, 2 times faster than the ARCH-I, and also have a fixed small amount of hardware overhead. The simulation results ascertain the correct operation and effectiveness of the proposed architectures and test procedure. |
