Abstract

The large size of modern FPGAs has caused researchers to consider deploying hierarchical techniques in their design. In this paper, we consider the floorplanning of FPGAs. We present a two-step approach for the floorplanning of modern FPGAs that we believe is cleaner and more versatile than recent floorplanners. The steps, based on resource-aware fixed outline simulated annealing and constrained floorplanning, are adapted to address the heterogeneous nature of FPGA floorplanning. Experiments demonstrate the viability of our approach.
