DeFer: deferred decision making enabled fixed-outline floorplanner
In this paper, we present DeFer -- a fast, high-quality and nonstochastic fixed-outline floorplanning algorithm. DeFer generates a non-slicing floorplan by compacting a slicing fl...

RQL: Global Placement via Relaxed Quadratic Spreading and Linearization
This paper describes a simple and effective quadratic placement algorithm called RQL. We show that a good quadratic placement, followed by local wirelength-driven spreading can pr...

An Integer Linear Programming Based Routing Algorithm for Flip-Chip Design
The flip-chip package provides a high chip-density solution to the demand for more I/O pads of VLSI designs. In this paper, we present the first routing algorithm in the literatur...

MP-trees: A Packing-Based Macro Placement Algorithm for Mixed-Size Designs
In this paper, we present a new multi-packing tree (MP-tree) representation for macro placement to handle mixed-size designs. Based on binary trees, the MP-tree is very efficient,...
