Clock-skew adjustment and data-path synthesis are simultaneously costed to obtain the best solution for timing, area, power, DRC and routability.

There is no relation b/w insertion delay and clock frequency, but for a subchip it is derived from the top level specification, ideally it is kept as small as possible considering the effects of jitter and dynamic power consumption.

Webb7 aug. 2013 · `Skew = 20ns-5ns = 15ns` The goal of clock tree synthesis is to get the skew in the design to be close to zero. i.e. every clock sink should get the clock at the same time. Power – Clock is a major power consumer in your design. Clock power consumption depends on switching activity and wire length.
