Machine learning (ML) has been applied to many EDA problems in recent years. We can classify these applications into three major categories: Predictor, Optimizer and Generator based on the role of ML played in these applications and the ML techniques used. Ideally one would like to adopt the Optimizer and Generator approaches to solve a hard EDA problem directly with ML, and we call these ML-alone approach. It is very challenging, however, to scale the ML-alone approach to solve real world EDA problems.

High-throughput RTL simulation is critical for verifying today’s highly complex SoCs. Recent research has explored accelerating RTL simulation by leveraging event-driven approaches or partitioning heuristics to speed up simulation on a single stimulus.

In this paper, we present the first Power, Performance, and Area (PPA)-directed, end-to-end placement optimization framework that provides cell clustering constraints as placement guidance to advance commercial placers. Specifically, we formulate PPA metrics as Machine Learning (ML) loss functions, and use graph clustering techniques to optimize them by improving clustering assignments.

Accurate crosstalk-aware timing analysis is critical in nanometer-scale process nodes. While today's VLSI flows rely on static timing analysis (STA) techniques to perform crosstalk-aware timing signoff, these techniques are limited due to their static nature as they use imprecise heuristics such as arbitrary aggressor filtering and simplified delay calculations. This paper proposes XT-PRAGGMA, a tool that uses GPU-accelerated dynamic gate-level simulations and machine learning to eliminate false aggressors and accurately predict crosstalk-induced delta delays.

Unsupervised generation of high-quality multi-view-consistent images and 3D shapes using only collections of single-view 2D photographs has been a long-standing challenge. Existing 3D GANs are either compute-intensive or make approximations that are not 3D-consistent; the former limits quality and resolution of the generated images and the latter adversely affects multi-view consistency and shape quality. In this work, we improve the computational efficiency and image quality of 3D GANs without overly relying on these approximations.

Driver distraction is a serious threat to automotive safety. The visual-manual interfaces in cars are a source of distraction for drivers. Automotive touch-less hand gesture-based user interfaces can help to reduce driver distraction and enhance safety and comfort. The choice of hand gestures in automotive interfaces is central to their success and widespread adoption. In this work we evaluate the recognition accuracy of 25 different gestures for state-of-the-art computer vision-based gesture recognition algorithms and for human observers.

Instance segmentation is a fundamental vision task that aims to recognize and segment each object in an image. However, it requires costly annotations such as bounding boxes and segmentation masks for learning. In this work, we propose a fully unsupervised learning method that learns class-agnostic instance segmentation without any annotations. We present FreeSOLO, a self-supervised instance segmentation framework built on top of the simple instance segmentation method SOLO.

Grouping and recognition are important components of visual scene understanding, e.g., for object detection and semantic segmentation. With end-to-end deep learning systems, grouping of image regions usually happens implicitly via top-down supervision from pixel-level recognition labels. Instead, in this paper, we propose to bring back the grouping mechanism into deep networks, which allows semantic segments to emerge automatically with only text supervision.
