1.5.1. Step 1: Create a Project Revision

Follow these steps to create a new project revision for import of the preserved partition:
  1. From the tutorial_base directory, copy the following files into the tutorial_impl directory:
    • top.qsf—to include the partition and Logic Lock settings in the new revision of the project.
    • root_partition.qdb—to apply the final snapshot .qdb as the root partition of the new revision.
  2. In top.qsf, remove the following line: 
    set_instance_assignment -name EXPORT_PARTITION_SNAPSHOT_FINAL \
     root_partition.qdb -to | -entity top
  3. Save top.qsf.
