WebHierarchical Approach :: Bottom-Up • Hierarchical approach works best in bottom-up fashion. • Modules are represented as vertices of a graph, while edges represent connectivity. – Modules with high connectivity are clustered together. • Number of modules in each cluster ≤≤≤ d. – An optimal floorplan for each cluster is determined by WebWith the rapid increase in size and complexity of VLSI, it is hard to meet speed and quality requirement of IC physical design. In this paper, we present an efficient model for quick floorplanning in VLSI top-down hierarchical physical design flow using the Active-Logic Reduction Technology. The simplified model replaces some original modules in netlist … normally healthy tongue yellow boxes
