Even when routing fails, the router continues and tries to provide a design that is as complete as possible to aid in debug. If the routing is not complete, you might have to intervene manually.
The router reports routing congestion during Route finalize. The highest congested regions are listed for each direction (North, East, South, and West). For each region, the information includes the dimensions in routing tiles, the routing utilization labeled "Max Cong," and the bounding box coordinates (lower-left corner to upper-right corner). The “INT_xxx” numbers are the coordinates of the interconnecting routing tiles that are visible in the device routing resource view.
|report_route_status||Reports route status for nets|
