Fixed-outline floorplanning: enabling hierarchical design
Classical floorplanning minimizes a linear combination of area and wirelength. When Simulated Annealing is used, e.g., with the Sequence Pair representation, the typical choice of moves is fairly straightforward. In this work, we study the fixed-outline floorplan formulation that is more relevant to hierarchical design style and is justified for very large ASICs and SoCs. We empirically show th...
متن کاملLarge-Scale Fixed-Outline Floorplanning Design Using Convex Optimization
A two-stage optimization methodology is proposed to solve the fixed-outline floorplanning problem that is a global optimization problem for wirelength minimization. In the first stage, an attractor-repeller convex optimization model provides the relative positions of the modules on the floorplan. The second stage places and sizes the modules using second-order cone optimization. With the relati...
متن کاملOn Objective Functions for Fixed-Outline Floorplanning
-Fixed-outline floorplanning enables multilevel hierarchical design, where aspect ratios and area of floorplans are usually imposed by higher level floorplanning and must be satisfied. Simulated Annealing is widely used in the floorplanning problem. It is well-known that the solution space, solution perturbation, and objective function are very important for Simulated Annealing. In this paper, ...

متن کاملAn iterative merging placement algorithm for the fixed-outline floorplanning
Given a set of rectangular modules with fixed area and variable dimensions, and a fixed rectangular circuit. The placement of Fixed-Outline Floorplanning with Soft Modules (FOFSM) aims to determine the dimensions and position of each module on the circuit. We present a two-stage Iterative Merging Placement (IMP) algorithm for the FOFSM with zero deadspace constraint. The first stage iteratively...
