Area-Driven Decoupling Capacitance Allocation in Noise-Aware Floorplan for Signal Integrity

In this paper, based on a flexible decap estimation model to predict the allocated decap of any circuit module 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.
