WebThen New hold time (Thold new) = Thold - Tcomb = 2ns - 1 ns =1ns (positive hold time) If Tcomb = 2ns Thold new = Thold – Tcomb = 2ns – 2ns = 0 ns (zero hold time) If the comb logic is equal to internal clock delay then our hold time will be zero if hold time is zero it means no need to hold the data after the clock edge has arrived. If ... WebOct 6, 2016 · For this particular part, the minimum hold time required is 3nsec. This is the minimum amount of time the input must be stable behind the clock for guaranteed performance (i.e. D is transferred to Q) Any transition of the input after this is effectively ignored by the device.

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. foam sheets for soundproofing

WebOct 27, 2024 · You will need to add delays to the clock and/or data signal to the specific flip-flop in question. Adding delay to the data input increases the effective setup time, while adding delay to the internal clock signal increases the effective hold time. The clock-to-q delay is controlled by delays added to the input clock as well as to the output q.
