Steering logic

Steering logic includes multiplexers. They are treated in the same fashion as RTL DPUs. The power consumption is based on their RTL power macro-model [1]. The power models play a similar role that power-pattern tables play for wire power estimation. They record the energy consumption figures for different input switchings. By profiling the input trace, we can get the total power consumption by simply counting all different switchings. Just as in the case of wires, the input switching activity of steering logic depends on the output switching activity of functional units and registers, and hence on binding given a schedule.
