Dummy Fill Insertion

Published:

We present DFI, a fill optimization framework with multiple objectives and constraints.

  • DFI Overview
    • We develop a high-performance framework for dummy fill insertion based on geometric properties instead of tiles.
    • The DFI framework optimizes multiple objectives such as density uniformity, overlay and output file sizes.
    • Experimental results show that our algorithms outperform the top teams by over 10% on ICCAD 2014 DFM contest benchmarks.
