WebHowever, excessive negative skew may create a hold-time violation, thereby creating a lower bound on TSkew ( i, f) as described by equation 4.6 and illustrated by l in Figure 4.2. A hold-time violation is a clock hazard or a race condition, also known as double clocking ( Friedman, 1995; Fishburn, 1990 ). WebSkew is the time delta between the actual and expected arrival time of a clock signal. Skew can be either extrinsic or intrinsic. The latter is internal to the driver (generator circuitry) …
