While hold time is the the time taken by the clock to reach the storage element. Now if you see the internal architecture of the Flip Flop, you will find that the path is longer for the data ( have 3 logic element in the path) while for the clk ... NettetHowever, 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 ).
