New AI tool PPAPlace optimizes chip placement for better performance

By PulseAugur Editorial · [1 sources] ·

Researchers have developed PPAPlace, a novel AI-driven system designed to optimize chip placement for improved performance, power, and area (PPA). Unlike traditional methods that focus on half-perimeter wirelength (HPWL), PPAPlace uses a dual-stream predictor that combines graph attention and spatial convolution to predict post-route timing metrics like worst negative slack (WNS) and total negative slack (TNS). This approach allows gradients from these timing metrics to be fed back into the placement process, leading to significant improvements in WNS and TNS compared to existing baselines. AI

IMPACT This research could lead to more efficient chip designs by improving the accuracy of AI-based placement tools in predicting and optimizing critical timing metrics.

    PPAPlace: Differentiable Cross-Stage Objectives for Chip Placement Optimization

    arXiv:2608.13790v1 Announce Type: cross Abstract: Macro placement significantly affects a chip's post-route performance, power, and area (PPA). Most placement methods optimize half-perimeter wirelength (HPWL) as the primary objective. However, recent benchmarking shows a near-zer…
