ISE - How to preserve the routing result of a previous run?

Description

Is there any way to preserve the routing result of an implementation run?

Solution

The following are some possible solutions:.

  1. Use Directed Routing Constraints in FPGA Editor to lock down the routing for selected nets.
     
  2. Use the Design Preservation Flow in PlanAhead.
    Set a module as partition and its preservation level as routing, so that the implementation result of this module can be preserved when this partition is imported.
