Definition
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. The amount of glitch is proportional to the number of operations executed by the SoC, making glitch an important problem to address for artificial intelligence (AI) accelerators, where tiles are executing many operations. Since glitches can cause potential electro-mechanical (EM) and IR drop issues (even in the power grid), they should be suppressed by the designers or via implementation or ECO tools.
