Abstract:
Systems and methods disclosed herein provide for an integrated circuit partitioned into a plurality of regions of a two-dimensional grid, wherein each region of the grid corresponds to similarly located scan flops. The systems and methods also provide for enabling clock gates to scan flops in some regions of the integrated circuit and disabling clock gates to other regions in order to better manage power dissipation during ATPG. Specifically, toggle disabling templates are applied during ATPG in order to enable clock gates in certain regions of the two-dimensional grid.
