Area-driven decoupling capacitance allocation based on space sensitivity analysis for signal integrity

In this paper, based on the space sensitivity for the decoupling capacitor to release the IR-drop constraint and to minimize the final floorplan area in a given floorplan, an area-driven allocation approach is proposed to integrate the decap estimation and allocation to assign feasible decaps around or near all the circuit modules to release all the IR-drop noises in the floorplan. The experimental results show that our proposed area-driven allocation approach obtains very promising timing and area results for MCNC benchmark circuits.
