Clock distribution network

Many DPUs are clocked. Such units include controllers, registers and pipelined functional units. In the floorplanner, we increase the communication cost between clocked units in order to place them closer to each other. After floorplanning, an MST is constructed for these clocked units. The power consumption of the MST is estimated using unit-length switched capacitance and the total length of the MST.
