With today's advanced integrated circuits (ICs) manufacturing technology in deep submicron (DSM) environment, we can integrate entire electronic systems on a single chip (SoC). However, without careful power supply planning in layout, the design of chips will suffer from mostly signal integrity problems including IR-drop, ΔI noise, and IC reliability. Postroute methodologies in solving signal integrity problem have been applied but they will cause a long turn-around time, which adds costly delays to time-to-market. In this paper, we study the problem of power supply noise avoidance as early as in floorplanning stage. We show that the noise avoidance in power supply planning problem can be formulated as a constrained maximum flow problem and present an efficient yet effective heuristic to handle the problem. Experimental results are encouraging. With slight increase of total wirelength, we achieve almost no-IR-drop requirement violation and 46.6% of improvement on ΔI noise constraint violation compared with a previous approach.
