MAPLE: multilevel adaptive placement for mixed-size designs
TL;DR: A new multilevel framework for large-scale placement called MAPLE is proposed that respects utilization constraints, handles movable macros and guides the transition between global and detailed placement.
Proceedings ArticleDOI
New placement prediction and mitigation techniques for local routing congestion
TL;DR: This work models routing congestion at the placement level in order to apply local congestion mitigation and proposes a local congestion metric that computes a “routing-difficulty” score for every cell in the design library.

Automatic Positioning of Gate Array Circuits in an Integrated Circuit Design
TL;DR: In this article, an automated method and apparatus for positioning gate array circuits in an integrated circuit design is presented, which allows full utilization of any space remaining between the adjacent logic cells by gate array fill circuits.
Proceedings ArticleDOI
DRC Hotspot Prediction at Sub-10nm Process Nodes Using Customized Convolutional Network
TL;DR: A new convolutional neural network technique, J-Net, is introduced for the prediction with mixed resolution features of DRC hotspot prediction, which can improve true positive rate by 37%, 40% and 14% respectively, compared to three recent works, with similar false positive rates.
Proceedings ArticleDOI
