I think it means glitch-free with the worst-case device delay skew in the transition window like switching PLL clocks in a CPU. Pessimism means worst case. Getting rid of it means the transition window must be wider the skew of parts so there is no glitch. Last edited: Oct 23, 2024 Upvote 0 Downvote
