Modern circuits become harder to route with the ever decreasing design features. Previous routability-driven placement techniques are usually tightly coupled with the underlying placers. So usually they cannot be easily integrated into various placement tools. In this paper, we propose a tool called CROP (Congestion Refinement of Placement) for mixed-size placement solutions. CROP is independent of any placer. It takes a legalized placement solution and then relocates the modules to improve… CONTINUE READING
