Abstract:
A 2D scan tree structure for the measurable scan design of low-power IC includes scanning N registers. It features that a 2D array (LXH) composed of H groups of scan chain circuits and L groups of serial scan chain circuits is used to constitute a scan tree, where LXH=N. Its advantages are simple interconnection between registers, ability to constitute local scan chain as required, and low requirement to optimize timer tree.
