3.5.1.1. Areas with Routing Congestion

Even if average congestion is not high, the design may have areas where congestion is high in a specific type of routing. You can use the Chip Planner to identify areas of high congestion for specific interconnect types.
  • You can change the connections in your design to reduce routing congestion
  • If the area with routing congestion is in a Logic Lock region or between Logic Lock regions, change or remove the Logic Lock regions and recompile your design.
    • If the routing time remains the same, the time is a characteristic of your design and the placement
    • If the routing time decreases, consider changing the size, location, or contents of Logic Lock regions to reduce congestion and decrease routing time.
