Top Verification of Low Power System with “Checkerboard” Approach
Low power management is a critical design front for complex wireless systems. Not only different natures of the blocks required different power supplies (1.5V, 2.5V). Blocks are switched on and off sequentially during the duty to save power. A simple connection error can damage or destroy a block. Top level verification of such a complexity is required to guaranty the quality and the robustness of the final product.
