where is the number of terminals, the number of blocks within the chip, the average number of terminals for one block and the Rent exponent. Rent's rule has been widely used to estimate power dissipation in interconnects. In [55], it is used to estimate the number of interconnects. The total interconnect power dissipation is estimated based on that number, average interconnect length and average fanout number for interconnect. In [56], the authors obtained a stochastic distribution of wire length with the assumption that the same and hold for the chip as well as its different parts. They used the distribution to estimate wire power dissipation in [57]. The assumptions made about and , e.g., their values and whether they are constant, render the methodology barely useful for design space exploration. In high-level synthesis, different binding and scheduling algorithms may generate circuits with different and , as illustrated in Fig. 5.
