Secondary-Power-Cell-Aware Detailed Placement in Multiple Power Domain Designs
DescriptionUsing multiple power domains is crucial for power savings in modern designs, but advanced nodes face challenges in powering cross-domain cells due to IR drop constraints and resource competition between secondary power and signal routing. This paper presents a detailed placement method that integrates secondary power routing considerations. Leveraging an integer linear programming (ILP) model and targeted cross-domain cell placement adjustments, our approach optimizes secondary power routing efficiency. Validation with commercial design tools demonstrates improvements in secondary power routing performance by reducing the secondary power distribution network (PDN) wirelength and decreasing PDN constraint violations.
