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.
