WebAug 18, 2012 · The most effective way to test the scan chains, and to detect any broken scan chains, is using a dedicated ‘chain test pattern’ or ‘chain flush’ pattern. A chain test simply shifts a sequence, typically … WebNov 24, 2024 · The scan is inserted at the block level. When the blocks are assembled at the top level, the chains can be connected in one of two ways: concatenated or direct to I/O. In the concatenated scan chain approach, scan chains from one block are concatenated with chains from another block. Advantages/disadvantages of Hierarchical DFT:
