The find_routing_path Tcl command can be used to create directed routing constraints. You can then assign the created constraints to the FIXED_ROUTE property of a net to lock down the routing.

For partially routed nets, the nodes can be found associated directly to the net. Refer to the Vivado Design Suite Properties Reference Guide (UG912) for more information on the relationship between these objects.

The find_routing_path command returns one of the following:

  • A list of nodes representing the route path found from the start point to the end point.
  • no path found if the command runs but has no result.
  • An error if the command fails to run.
