WebTiming analysis done for the DFF and parameters such as Drop-Dead Setup Time (Tsu_dd), Optimal Setup Time (Tsu_opt), Hold Time (Thold) , Clock to Q Time (Tclk-Q) and delay were calculated. WebThold Tsetup FF and Latches have setup and hold times that must be satisfied: If Din arrives before setup time and is stable after the hold time, FF will work; if Din arrives after hold time, it will fail; in between, it may or may not work; FF delays the slowest signal by the setup + clk-q delay in the worst case

WebDec 7, 2024 · Yes. When the setup/hold is large enough, the delay of the flop remains close to the static delay. As setup/hold time reduces, the delay of the cell increases. We accept a delay that remains within 10% of the static delay. The setup/hold point where this occurs is defined as the cell specification.
