Issues In Calculating Glitch Power

Which of the growing number of corners must be addressed?


The amount of power consumed by redundant non-functional toggles, or glitch power, can be as high as 35% of total power consumption in a design. What can be done about that? Godwin Maben, low-power architect and scientist at Synopsys, takes a deep dive into the causes of glitch, how it is affected by new process nodes and heterogeneous integration, and the impact of different workloads, higher dynamic power, thermal effects, and aging. The problems are particularly challenging with compute-intensive designs, and solutions are incomplete.
