Ripple: an effective routability-driven placer by iterative cell movement
TL;DR: Experimental results show that Ripple is very effective in improving routability and can further improve the overflow by 38% while reduce the runtime is reduced by 54%.
Proceedings ArticleDOI
Ripple 2.0: high quality routability-driven placement via global router integration
TL;DR: This paper presents a high quality placer Ripple 2.0 to solve the routability-driven placement problem and proposes several techniques, including lookahead routing analysis with pin density consideration, routing path-based cell inflation and spreading and robust optimization on congested cluster.
Proceedings ArticleDOI
Cell density-driven detailed placement with displacement constraint
TL;DR: This paper proposes a detailed placement algorithm for minimizing wire-length, while preserving the global placement solution by cell displacement constraint and target cell density objective.
Journal ArticleDOI
Ripple: A Robust and Effective Routability-Driven Placer
TL;DR: A routability-driven placer called Ripple is described, which can obtain the smallest overflow and half-perimeter wirelength on average, while the congestion hot spots are also distributed sparsely in Ripple.
Proceedings ArticleDOI
SRP: simultaneous routing and placement for congestion refinement
TL;DR: An effective simultaneous routing and placement refinement tool called SRP is proposed for routability improvement, independent of any placer and global router, and can reduce the overflow effectively.
