What is the difference between Glitch power and Glitch power?

In electronics design, glitch refers to unnecessary signal transitions in a combinational circuit, while glitch power refers to the power consumed by glitches. The extra switching activity can lead to up to 40% of additional dynamic power consumption.

Why should glitching be eliminated for low power design?

Glitch power comes under dynamic dissipation in the circuit and is directly proportional to switching activity. Glitch power dissipation is 20%–70% of total power dissipation and hence glitching should be eliminated for low power design. Switching activity occurs due to signal transitions which are of two types: functional transition and a glitch.

What is Glitch power & why is it important?

Glitch power can represent up to 40% of the total power. In addition, due to the symmetric and replicated architecture of AI hardware, it is very important to identify the best possible micro-architecture for glitch early in the design cycle and, ideally, at the system level or RTL level.
