Invited Paper: Accelerating Routability and Timing Optimization with Open-Source AI4EDA Dataset CircuitNet and Heterogeneous Platforms

Routability and timing are two critical metrics for modern VLSI circuits. With increasing design complexity and continuous shrinking of technology nodes, optimizing routability and timing become extremely expensive due to high computational overhead for analysis. It is reported that conventional CPU-based parallelization strategies can no longer scale beyond 8–16 threads. In this talk, we introduce how to accelerate routability and timing optimization leveraging AI-enabled GPU acceleration. To break the inter-stage information dependency in conventional physical design flow, we build AI for EDA models with an open-source dataset, CircuitNet, to enable ultrafast design optimization on GPU. We hope our study can shed lights to future development of EDA tools with AI-enabled heterogenity.
