Advanced Node Solutions Overview
Designing at 22nm and below advanced nodes presents unique challenges due to the intricate interdependence of manufacturing, variability, power, and performance requirements. Components like multiple-patterning technology (MPT), color-aware physical design, layout-dependent effects (LDE), and density-gradient effects (DGE) add complexity. Custom routing, increasing physical design rules, and device variation sensitivity contribute to the intricate nature of designs at these nodes.
