Power-Driven Global Routing for Multisupply Voltage Domains

Figure 1

Motivation for power-aware GR.

(a) Shortest-length GR results in overflow (OF)

(b) Wirelength-based GR trades off increase in wirelength (WL) with decrease in OF

(c) Power-aware GR makes the high power consuming net shorter with minimal increase in WL and decrease in OF
