Delay calculation is the term used in integrated circuit design for the calculation of the gate delay of a single logic gate and the wires attached to it. By contrast, static timing analysis computes the delays of entire paths, using delay calculation to determine the delay of each gate and wire.
Determining the propagation delay of a combined circuit requires identifying the longest path of propagation delays from input to output, and adding each propagation delay along this path. The difference in propagation delays of logic elements is the major contributor to glitches in asynchronous circuits as a result of race conditions.

The propagation delay of a physical link can be calculated by dividing the distance (the length of the medium) in meter by its propagation speed in m/s. Propagation time = Distance / propagation speed. Example: Ethernet communication over a UTP copper cable with maximum distance of 100 meter between computer and switching node results in:
To calculate the arrival time, delay calculation of all the components in the path will be required. Arrival times, and indeed almost all times in timing analysis, are normally kept as a pair of values - the earliest possible time at which a signal can change, and the latest.
The Electronic Delay Storage Automatic Calculator (EDSAC) was an early British computer. [1] Inspired by John von Neumann's seminal First Draft of a Report on the EDVAC, the machine was constructed by Maurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England.
Elmore delay [1] is a simple approximation to the delay through an RC network in an electronic system. It is often used in applications such as logic synthesis, delay calculation, static timing analysis, placement and routing, since it is simple to compute (especially in tree structured networks, which are the vast majority of signal nets within ICs) and is reasonably accurate.
In radio technology, symmetrical double-sided two-way ranging (SDS-TWR) is a ranging method that uses two delays that naturally occur in signal transmission to determine the range between two stations: [1] Signal propagation delay between two wireless devices; Processing delay of acknowledgements within a wireless device
