Floorplacement in Dynamic Reconfigurable FPGA-based Systems: An innovative Time-Driven Reconfiguration Aware Floorplanner and Placer
A. Montone · 2009
Nowadays one of the most important design style for Very Large Scale Intergrated (VLSI) circuits is represented by Field Programmable Gate Arrays (FPGA). Since their introduction in the early 90s, FPGAs provided new challenges to the existing VLSI design automation techniques. FPGAs, due to their internal architecture, require new techniques (or improvement to the existing ones) for each step of the design ow. The oorplanning automation for FPGAs is a current research topic, in order to face the new challenges provided by FPGAs. FPGAs presents two new aspects with respect to classical VLSI design automation techniques: Resource Heterogeneity and Reconfigurability. This book focuses on the problem of nding an area assignment for each module, i.e. nd an area where it has to be congured. Aim of this book is to provide a formalization of the problem and an approach (divided in three algorithms) to solve such problems. The innovative contribution of this book consists in facing area assignment problem taking concurrently into account FPGAs heterogeneity and reconguration limits. Furthermore the proposed approach takes into account inter-module communication issues.
