A design must contain these enable conditions in order to use and benefit from clock gating. This clock gating process can also save significant die area as well as power, since it removes large numbers of muxes and replaces them with clock-gating logic. This clock-gating logic is generally in the form of "integrated clock gating" (ICG) cells.
The goal of signal gating is to selectively allow or block the transmission of signals through a circuit or system. In signal gating, a gating signal is used to modulate the passage of the main signal. The gating signal acts as a control mechanism, determining when the main signal can pass through the gate and when it is blocked.

Frequency-resolved optical gating (FROG) is a general method for measuring the spectral phase of ultrashort laser pulses, which range from subfemtosecond to about a nanosecond in length. Invented in 1991 by Rick Trebino and Daniel J. Kane, FROG was the first technique to solve this problem, which is difficult because, ordinarily, to measure an ...
Power gating is a technique used in integrated circuit design to reduce power consumption, by shutting off the current to blocks of the circuit that are not in use. In addition to reducing stand-by or leakage power, power gating has the benefit of enabling Iddq testing .

Measuring the ability of a circuit to operate at the specified speed requires an ability to measure, during the design process, its delay at numerous steps. Moreover, delay calculation must be incorporated into the inner loop of timing optimizers at various phases of design, such as logic synthesis , layout ( placement and routing ), and in in ...
A common file format for storing the lookup tables is the Liberty [2] [3] format. A very simple model called the K-factor model is sometimes used. This approximates the delay as a constant plus k times the load capacitance. A more complex model called Delay Calculation Language, [4] or DCL, calls a user-defined program whenever a delay value is ...
