propagation delay

[‚präp·ə′gā·shən di‚lā]
(electronics)
The time required for a signal to pass through a given complete operating circuit; it is generally of the order of nanoseconds, and is of extreme importance in computer circuits.

propagation delay

The time it takes to transmit a signal from one place to another. Propagation delay is dependent solely on distance and two thirds the speed of light. Signals going through a wire or fiber generally travel at two thirds the speed of light. Contrast with nodal processing delay.

As the carry signal propagates only through the single transmission gate, the carry propagation path is minimized leading to a substantial reduction in propagation delay.
Propagation delay skew, tpsK, is an important parameter to consider in parallel data applications where synchronization of signals on parallel data lines is a concern.
If the clock is generated inside one of the chips, then the clock propagation delay to that chip would be zero, while to the other chips it would be based on the on-board routing.
