Researchers from University of Alberta published a technical paper titled “PPAPlace: Differentiable Cross-Stage Objectives for Chip Placement Optimization.” 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-zero correlation between HPWL and post-route timing metrics... » read more The post Predicting Post-Route PPA from Macro and Standard-Cell Placements (U. of Alberta) appeared first on Semiconductor Engineering .
