188.8.131.52. 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.
