WebAug 24, 2015 · The setup time is how long the input data needs to be held fixed before the clock, and hold time is how long it needs to remain fixed after the clock. If either of these specs is violated, then the answer is you don't know what state the output will settle at. Some flipflops have either a 0 setup time or 0 hold time. granitestone diamond 12 inch fry pan

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. WebSTA applies a concept of time borrowing for latch based designs. Whatever data launched from Flip Flop1 at ons it should be reached to Flip Flop2 at next active edge i.e. 10ns (ideal case when setup hold time and skew and clock delay all are zero). If data reaches at Flip Flop2 after 10ns will not be able to capture the correct data.
