Abstract :
In traditional physical-synthesis methodologies, the placement of flip-flops and latches is problematic, especially for large systems on chips. A next-generation electronic-design-automation methodology improves timing closure through clock-network synthesis and placement of flip-flops and latches to avoid timing disruptions or immediately recover from them. When evaluated on large CPU designs, the methodology saw double-digit improvements in timing, wirelength, and area versus current technology.
