Abstract
A local clock buffer for improving energy efficiency using a power saving clock buffer for clock grid-based scanning includes a grid node that receives a global clock signal from a global clock grid; a clock enable latch configured to latch a clock enable signal, wherein the clock enable latch is clocked based on the global clock signal; a clock gate configured to output a functional clock signal in dependence upon a latched value of the clock enable signal; a scan clock enable latch configured to latch a scan enable signal, wherein the scan enable latch is a non-clocked latch; and a scan clock gate coupled to the output of the functional clock gate and configured to output a scan clock signal in dependence upon a latched value of the scan enable signal.
