What is the propagation delay of a flip flop?
The amount of time it takes for the output of the first Flip-Flop to travel to the input of the second Flip-Flop is the Propagation Delay. The further apart those two Flip-Flops are or the more combinational logic in the middle, the longer the propagation delay between the two of them.
What is maximum propagation delay?
The propagation delay tpd is the maximum time from when an input changes until the output or outputs reach their final value. The contamination delay tcd is the minimum time from when an input changes until any output starts to change its value.
How do you calculate max propagation delay?
It can be computed as the ratio between the link length and the propagation speed over the specific medium. Propagation delay is equal to d / s where d is the distance and s is the wave propagation speed. In wireless communication, s=c, i.e. the speed of light.

What is the propagation delay of two flip flops?
In the Figure above, there are two Flip-Flops that are connected together with some logic and routing (wires) between them. The amount of time it takes for the output of the first Flip-Flop to travel to the input of the second Flip-Flop is the Propagation Delay.
How does the propagation delay affect the clock?
The longer the propagation delay, the slower your clock is able to run. The reason for this is that both Flip-Flops use the same clock. The first Flip-Flop drives its output at clock edge 1. The second Flip-Flop does not see the change on the output of the first Flip-Flop until clock edge 2, at which point it drives its output.
How long does it take for a flip flop to travel?
The amount of time it takes for the output of the first Flip-Flop to travel to the input of the second Flip-Flop is the Propagation Delay. The further apart those two Flip-Flops are or the more combinational logic in the middle, the longer the propagation delay between the two of them.
What is the maximum propagation delay of latch I?
Δ dqi: the maximum propagation delay of latch i from the data input to the data output while the clock input is high Finally, define the propagation delays between pairs of latches: Δ ij: the maximum propagation delay through combinational logic between latch i and latch j.
