Development and Optimization of Multiple Supply Voltage Floorplanning Algorithms for Modern ICs

Abstract

The objective of this research is to a develop floorplanning algorithm that facilitates newlinethe physical design methodologies for integrated circuit (IC) designs using Multiple newlineSupply Voltages (MSV) and implementing in various design stages to evaluate the improvements newlinein the performance. newlineFloorplanning in MSV ICs is one of the last challenges in back-end process as it newlinerequires compatibility in satisfying voltage island and fixed outline constraints. First, a newlinemodified floorplanning technique for MSV designs is developed. Next, the algorithm newlineis implemented to a commercial EDA environment under various fixed aspect ratios, newlinealong with a study on how the proposed algorithm mitigate to satisfy voltage island newlineconstraints. Finally, the algorithm is performed to satisfy both fixed outline and voltage newlineisland constraints. newlineVoltage drop reduction in the power ground network has become a challenging problem newlinein the modern multiple supply voltage designs. An effective P/G network design newlineand floorplanning of modules produce a quality power plan in the layout. Hence, this newlineresearch proposes an iterative MSV floorplanning methodology that performs modifications newlinein the skewed binary tree representation to satisfy the voltage island constraint newlineand produce an IR drop-aware quality layout newline
