Observe these rules during manual routing:

  • The driver and the load require a LOC constraint and a BEL constraint.
  • Branching is not allowed during manual routing, but you can implement branches by starting a new manual route from a branch point.
  • LUT loads must have their pins locked.
  • You must route to loads that are not already connected to a driver.
  • Only complete connections are permitted. Antennas are not allowed.
  • Overlap with existing unfixed routed nets is allowed. Run route_design after manual routing to resolve any conflicts due to overlapping nets.
