Abstract: Conventional physical design flow separates the design of power network and signal network. Such a separated approach results in slow design convergence for wire-limited deep sub-micron designs. We present a novel design methodology that simultaneously considers global signal routing and power network design under integrity constraints. The key part to this approach is a simple yet accurate power net estimation formula that decides the minimum number of power nets needed to satisfy both power and signal integ…
