Evaluating routing congestion based on average global edge congestion histograms

摘要: Receive Globally Routed Netlist. With Global Wiring Assignments For Current Design global edges are handled separately. Global edges near block ages can be skipped to avoid false congestion hotspots. The histogram of the current global routing can be compared to a histogram for a previous global routing to selecta best routing Solution. The histograms can also be used in conjunction with congestion-driven physical synthesis tools.
